A Day as Royalty: A Stroll Through Marunouchi

The Hotel Built in the Sky %sTHE TOKYO STATION HOTEL

It’s not walking on clouds, nor is it a skyscraper slicing the skyline—not an imagined or promotional “city in the sky.” The Tokyo Station Hotel, THE TOKYO STATION HOTEL, is truly a hotel built in the sky. “The Marunouchi Station Building itself is an important national cultural property, which generally qualifies for government subsidies. But this time, the restoration work and interior renovation were entirely funded by us. So we sold the sky to restore the station building’s exterior and renovate the hotel interior,” said Public Relations Manager Ms. Hamashunako. Because the Marunouchi Station Building is a government-designated historic site, regulations limit the height of surrounding buildings to maintain urban harmony and preserve heritage. What Ms. Hamashunako refers to is how Tokyo Station transferred the air rights above the station to a consortium, lifting height restrictions for nearby commercial buildings. The funds gained from this transfer became the capital that restored the Marunouchi Station Building and the Tokyo Station Hotel within it to their former glory. Thus, the Tokyo Station Hotel is the world’s one and only hotel built in the sky. Neither close to the sky, nor entirely abstract—it’s very real.

Classical Elegance, Modern Expression

Losing the skyline, Tokyo Station gained the favor of time. The Tokyo Station Hotel within the Marunouchi Station Building reinterprets the demeanor of a refined commoner with a brand-new look. A hotel integrated with the station often carries the stereotype of existing solely for convenience, but the Tokyo Station Hotel has always been Tokyo’s gateway—and even the face of royalty. Whether in its original British-style charm at opening or its modern-classical makeover today, the Tokyo Station Hotel is both a reflection and embodiment of the spirit of the times.

Stepping into the Tokyo Station Hotel requires shifting into another pace. While the adjacent station entrance buzzes with noise all day, here there is a low-key elegance akin to a boutique hotel. The lobby, like those in rare-room boutique hotels abroad, is simple and grand in beige tones, accented with custom-designed furnishings and lighting. A discreet counter waits quietly for guests, while staff and visitors move as if by unspoken agreement—with light footsteps and hushed voices. The space is small but exquisitely private; understated yet naturally shielding visitors from the bustling crowds, harmonious and graceful, luxurious without being ostentatious.

Turn right, and you’ll find the spacious Lounge. “This used to be a waiting room and has now been renovated into a lounge serving snacks and drinks. The space is completely different now, but many older guests still remember how it used to be and come here specifically to relive the old times,” says Ms. Hamashunako. A century ago, waiting rooms might have offered only cheap boxed meals, amid the noise of children, cigarette smoke, and the bittersweet sorrow of parting. Today’s Lounge exudes the elegance of an English afternoon tea—rows of tall windows, geometric-patterned carpets, and furniture in rich colors of navy, burgundy, and beige, composing a picture so vivid it stands out even in black and white. Past 10 a.m., during high tea, the Lounge fills with guests, though this time they’re not in a rush to depart, instead savoring this first stop filled with a century’s worth of shared joy.

A Bar of Shared Memories

If you’re seeking a quiet place to be alone, Bar Oak and Camella are sanctuaries for all weariness and solitude. Step into Bar Oak, where bronze leather sofas and boxy tables are veritable antiques, their luster honed by countless visitors over time, glowing with true character. The reddish-brick wall above is exposed stonework revealed during renovation, radiating gentle nostalgia under warm lighting, preserving a century of Tokyo’s time.

The long bar and cabinets display a variety of spirits. Over fifty years ago when it first opened, this was one of the few upscale gentleman’s bars in Tokyo, where many iconic cocktails were born and trends were set. But none of that compares to the legendary bartender Mr. Koichi Sugimoto, 73, presiding over Bar Oak. “Marunouchi is home to many in finance. After work, office workers would stop by for a drink, chat about their day with the bartender, and enjoy their own ‘healing time.’ That’s a shared memory for many. During the closure for renovation, hotel staff were reassigned to affiliate companies, and Mr. Sugimoto was temporarily loaned to another nearby hotel. Before reopening, the general manager asked if he’d like to return—and he did, bringing back the classics of the past,” says Ms. Hamashunako. Many guests return specifically for Mr. Sugimoto, perhaps just to chat like old times about work, family, and memories. There are even patrons who’ve known him for 40 years. Word-of-mouth drew such crowds in the months before reopening that people lined up daily just to try his exclusive cocktail, “Tokyo Station.” “A bartender serving at the same bar for 50 years—that’s truly one of a kind,” Ms. Hamashunako adds.

Another bar, Camella, faces the pristine white exterior of the newly opened KITTE complex. Sitting at the bar and gazing out at Marunouchi as night falls, nothing has changed in 60 years. Surrounded by muted bronze tones, seated on a plush velvet sofa in red-gray, you may feel as if you’ve slipped into the time and space of The Godfather. The engraved “STATION HOTEL” logo above the bar has been Camella’s sign since opening, and even after more than sixty years, it remains a companion to the weariness of travelers.

Flipping Tokyo Upside Down: A Hidden Dome-Level Amusement Park

Underground Sanctuary for Atheists %sMetropolitan Area Outer Underground Discharge Channel

Near W? (a placeholder for location), we heard stories and arrived at the facility. Just ten minutes away, the city quickly fades from view, and the scenery shifts: residential areas, rivers, parks, then small and medium enterprises, and industrial zones. Taking a taxi, across the open horizon, rivers carve gently rolling hills. This is W?, known as the “underground cathedral,” supporting Japan’s industrial development. In the latter half of the Showa era to Heisei 14 (about 20 years from the 1980s), the Naka River and Ayase River basin frequently flooded. Low elevation and overdevelopment were fatal flaws. The area, home to industrial zones that rose as Tokyo’s satellite cities, faced threats not only to lives but also, in the long run, to entire industrial supply chains. So they thought—let’s dig a river.

Not a Tourist Spot

“During the major floods in Thailand in July 2011, Japanese companies with factories there were also severely impacted. According to statistics from Japanese insurance companies, the total claims sought by Japanese businesses from domestic insurers amounted to 800 billion yen, while the total construction cost of the Metropolitan Area Outer Underground Discharge Channel was 230 billion yen,” said Takashi Komiyama, Director of the Management Branch of the Metropolitan Area Outer Underground Discharge Channel.

The online sensation known as the “Tokyo Underground Temple” is actually the Metropolitan Area Outer Underground Discharge Channel, spanning six rivers in Saitama Prefecture, including the Naka and Ayase Rivers. Comprising vertical shafts, drainage tunnels, pressure-regulating water tanks, and discharge sites, it essentially channels water from the basin into several deep vertical shafts about 70 meters deep and over 30 meters in diameter. These are connected by drainage tunnels, functioning like subterranean rivers. Water from the shafts is directed to pressure-regulating tanks for control before being discharged into the Edogawa River, achieving instant flood mitigation. The Naka and Ayase River basin, which flows into Tokyo Bay, suffered severe flooding from the late Showa era to Heisei 14 (approximately 20 years starting in the 1980s). Low elevation and excessive development were the root causes. The area, home to industrial zones that emerged as Tokyo’s satellite cities, faced life-threatening disasters and, in the long term, risks to the entire industrial chain. So they decided—let’s dig a river.

In fact, the Ministry of Land, Infrastructure, Transport and Tourism once considered digging a horizontal flood discharge channel on land, but abandoned the idea due to the complexity of land acquisition. “So the government passed a special law exempting public structures below 50 meters underground from property rights acquisition, solving our issue,” said Mr. Komiyama. Even so, the 230-billion-yen price tag for an invisible structure drew criticism, which is why public tours were initiated—to remind forgetful modern society of the hardships of floods, understand the importance of flood prevention, and witness the silent efforts of people working behind the scenes. “For regional safety and to prevent industrial relocation, this is something the nation must do.” The Thai floods made Japan rethink the fundamental issues of industrial relocation. “800 billion vs. 230 billion—think about which is the better deal.”

The tour begins with a video and model presentation, followed by an expert explanation of the discharge channel’s principles and functions. Visitors observe operations in the central control room, then head to the rooftop to survey the surrounding terrain, culminating in the highlight—descending underground. Since the vertical shafts and drainage tunnels are in constant use, they can’t be visited. The only accessible sight is the underground temple—the pressure-regulating water tank. Measuring 7 meters wide, 2 meters deep, and 18 meters high, it is supported by 59 concrete pillars, each weighing 500 metric tons. Surrounded and overlain by groundwater layers, and with the tank experiencing immense water pressure when full and rapid drainage at a rate equivalent to emptying a 25-meter standard short pool per second, the structure is awe-inspiring in its sheer massiveness. The air is filled with an oddly dry, secretive scent, deep and mysterious, as if stretching into infinity. The more vast and hollow it feels, the more one wonders—behind its grandeur, how many secrets lie dormant, ready to burst forth.

Behind the pressure-regulating water tank lies the side of the first vertical shaft. Looking through the drainage gate, you see a massive curved concrete wall, as if standing on the boarding platform of a space fortress. At the end, Mr. Komiyama, for our benefit, takes us to see the inner walkway of the vertical shaft and the giant pumps at the discharge site—areas normally off-limits. After navigating the vertigo-inducing inner walkway, Mr. Komiyama shows us the jet engines installed in the pumps. “To instantly drain the water from the pressure-regulating tank, you need jet-fighter-grade engines. But they also want to protect their cutting-edge tech, so even now, the most classified parts remain sealed and must be sent back to the U.S. for maintenance!”

Underground, it’s truly full of secrets.

Happy Tables with Attitude: A Sky-Market on the Boutique Boulevard

Healing Bites %sMinoru Shokudo

If you ask older folks about their impression of Tokyo, chances are more than nine out of ten will mention Ginza.

In the eyes of the older generation, whether in Japan or Taiwan, Ginza represents the pinnacle of luxury, an imagined life of the elite. If you tell these elders that you’re going to Ginza to eat small-scale farmer produce instead of Matsusaka beef or fugu sashimi, they’d probably think you’ve lost your mind.

Located on the terrace of the 9th floor of Mitsukoshi Department Store in Ginza, MinoruShitang (Minoru) is a small-farmers' canteen planned by Japan’s JA-Zenchu (National Federation of Agricultural Cooperative Associations).Outside the window is the bustling streets of Ginza, the prime battleground of high-end fashion. To old-time Tokyo residents, Ginza is the true social arena of the upper class; tourists walking the streets and sharply dressed doormen standing in front of luxury stores represent visible flows of wealth. But hidden in the alleys you might not notice are Michelin three-star restaurants. Ginza is a symbol of “living well.”

Backed by JA-Zenchu, MinoruShitang emphasizes seasonal and local concepts—all ingredients come from friendly-farming producers in the Tokyo suburbs, delivered fresh every morning and menu-designed based on what’s in season.Dining at Minoru gives you the exhilarating feeling of swinging for the fences: the ingredients are fresh and natural, the food simple and unpretentious, the flavors blending the heartiness of European country cooking with the gentleness of Japanese home-style dishes. It's not just the freshness of the vegetables that automatically triggers associations with a healthy lifestyle—it’s the color, aroma, and taste that are deeply soothing.

Positioning itself as an “exchange space between producers and urban dwellers,” MinoruShitang hopes that through food, city folk can choose a more natural way of life.Overcooking and heavy seasoning take a backseat, letting the ingredients speak for themselves. Especially when large chunks of simply simmered vegetables and aged bacon (gently bubbling vegetables and aged bacon) are served in a cast iron pot, the savory aroma of the vegetables mingles with the rich umami of the bacon—the softness of the vegetables complements the saltiness of the meat, each bite releasing bursts of earthy flavor and warmth.The aftertaste lingers softly yet follows a clear rhythm. You may unknowingly find yourself reflecting on your own values.

With its high ceilings, floor-to-ceiling windows, wooden and sage-green interiors, and a large terrace outside the window filled with greenery and sunbathing visitors, the pendant lights hanging in the evening resemble an orrery. A basket of fresh produce on the open kitchen counter tempts your appetite. Amidst the bustle of Ginza, there exists another way to “live well.”

A Journey Through a Vintage Space to Rediscover Childlike Wonder

The Artisan Space Beneath the Overpass: %s2k540 AKI-OKA ARTISAN

“Take out your phone,” urged Mr. Toyota Hirohiro, president of Creative Kaleidoscope, “watch the Up closely—that’s our secret technique!” He placed the phone on the table, set it to front-camera mode, then overlaid the kaleidoscope’s viewing window onto the lens.Both the lens and the window were tiny, making alignment tricky and the process rather frustrating—but suddenly, as if the frequencies had synced, the phone screen, which had been reflecting the ceiling, erupted into a dazzling burst of jewel-toned blocks. Geometric patterns tumbled and spun like Transformers within that tiny space, bursting forth in fireworks-like flashes. They floated unstably yet followed a distinct rhythm, vibrant and colorful. Just as the Japanese often say, “ichigo ichie”—a once-in-a-lifetime encounter in a specific time and mindset, never to be repeated—so too must it be cherished. Isn’t the beauty of a kaleidoscope just like that? Fleeting, and therefore all the more captivating. Perhaps it’s this cultural depth that draws such eccentrics, hiding beneath overpasses, to meticulously craft moments of beauty that can never be replicated.

Tokyo, the Town of Artisans

Walking south from Ueno Station and weaving through crowds of tourists, we searched for the arts space beneath the overpass. The elevated tracks above blocked most of the daylight, signs hung haphazardly, and the sounds of vendors and in-store music blended chaotically. We could’ve gotten to Okachimachi Station faster, but when it comes to overpasses, one naturally thinks of Ueno Station—the crisscrossing railways overhead evoked an old-school sci-fi atmosphere.

As a JR train sped overhead across the elevated tracks, the surrounding area grew quieter, though the disarray and worn-down feel—so unlike Tokyo—remained. The bleak landscape beneath overpasses seems to have no borders. Then we spotted whitewashed walls and design-savvy signage below the bridge—we had arrived at 2k540.

The full name of 2k540, or 2k540 AKI-OKA ARTISAN, carries many layers of meaning. “2K540” comes from railway terminology, representing the distance from Tokyo Station, i.e., 2 kilometers and 540 meters. “AKIOKA” refers to Akihabara Station and Okachimachi Station on the JR Yamanote Line, indicating its location beneath the overpass connecting these two stations. “ARTISAN” is French for “craftsman.” Typically, spaces beneath overpasses are repurposed as parking lots or warehouses, and even in older neighborhoods like Okachimachi, numerous food stalls hide under the bridges, often giving off a run-down impression. However, Okachimachi, where 2k540 is located, was once a hub for artisans, with many traditional craft workshops still in operation today, also attracting jewelry and leather workshops. JR East Urban Development Corporation, a subsidiary of East Japan Railway Company, sought to revitalize unused spaces and created 2k540—an arts and culture space beneath the overpass—with the concept of continuing the culture of the “town of artisans.”

Opening Dialogues Within the Space

But more than merely showcasing or selling handicrafts, 2k540 hopes to become a community exchange hub. Traditional workshops, with their focus on custom orders, have always played strong roles in communication and skill transmission. 2k540 takes inspiration from that. Among its roughly 50 workshops and shops, more than half feature artists and artisans working on-site, performing demonstrations, or even offering hands-on workshops. 2k540 also welcomes visitors to chat directly with the craftspeople. As an underutilized space, it had lost opportunities for interaction. To effectively use the space, bring people back, and create a place where creators and audiences meet, 2k540 formed a space that encourages gathering and dialogue. What 2k540 aims to explore is how much untapped potential can emerge from human interaction. Utilizing a space isn’t about stuffing it full, but about enabling conversations—and that’s the unique concept 2k540 has developed as a revitalized space.

It’s a town of artisans, so it gathers handmade and design goods; it transformed from an overpass into a new public space, so it attracts artisans and artists eager to speak directly to customers and let their works be heard; and due to the clustering effect, traditional custom commissions have become a platform for new generations to express their individuality. Various unique crafts converge beneath this short stretch of overpass, and wandering through the shops, you might stumble upon the most unexpected things.

Three-dimensional postcards that capture the charm of old neighborhoods, ceramic bowls with interior gradients of silver sand, wooden handmade keyboards, matte leather pouches—all winning points for craftsmanship, ingenuity, texture, and sense of daily life. But with so much beauty, how can you possibly take it all home? Then just take the stories. One such story comes from the kaleidoscope artisan, Mr. Toyota Hirohiro.

The Story of the Kaleidoscope

“My kaleidoscopes are not toys—they are artworks,” said Mr. Toyota. “You might throw away a toy or give it away, but you wouldn’t… ” Mr. Toyota Hirohiro, president of Creative Kaleidoscope, put aside his work and began sharing his journey with kaleidoscopes. From traditional ukiyo-e patterns to various shapes and materials, his kaleidoscopes have long transcended their role as mere toys, reaching the realm of fine craftsmanship. Retro aesthetics have always been a classic source of inspiration—classic, elegant designs with minimalist Japanese beauty that require no external validation. “Don’t just hand over a piece lightly. Keep it with you at all times, pick it up whenever you want, and create your own personal healing moment each day. Gradually, this object will form a connection with you, an emotional bond. Isn’t that what art is all about?” Setting down the kaleidoscope he was crafting, Mr. Toyota opened up to us, who had stumbled in by chance.

Stepping into Creative Kaleidoscope truly opened our eyes—we who had thought of kaleidoscopes as mere toys. Various shapes, materials, and modes of play, each piece encapsulates a tiny universe born purely from geometric patterns. “Traditional Japanese patterns and the geometry of kaleidoscopes are very similar—both are created by stacking, arranging, and repeating a single motif, so Japanese people are especially suited to this craft. Moreover, Japanese kaleidoscopes have moved beyond simply imitating Western techniques and aesthetics, merging traditional Japanese craftsmanship with cutting-edge industrial technology to develop truly unique pieces,” said Mr. Toyota.

Creative Kaleidoscope’s products are not only unique in design—their metal tubes use aerospace technology, some bases slide horizontally like test tubes, and others are even crafted from wine barrel wood. Holding the oak-grain wood, one wonders if the wine-red parts are truly polished by vintage wine? “There are so many ways to play with kaleidoscopes—different lighting, front-lit or back-lit, fast or slow spinning, and varying materials—all these variables create endless possibilities.” Mr. Toyota picked up one of their original products, aligned the base toward the light. The base held transparent oil with pattern-making materials floating inside. When turned, the patterns split and merged like cells. Changing the angle altered the interplay of light and shadow, producing completely different images.

So there we were, an old man and a young one, holding kaleidoscopes, tilting them up and down, darting around the shop, and having the time of our lives. If interpreting text is a form of recreation, then playing with a kaleidoscope must count as a form of creative participation.

All of Creative Kaleidoscope’s products come from the company’s artisans and independent makers, brimming with infinite interpretations of this two-hundred-year-old craft. Using existing materials and symbols to create new styles, redefining the old. Tiny variations spark maximum creativity, ultimately transforming the mundane into something entirely new. This is true for Creative Kaleidoscope’s kaleidoscopes, and for the 2k540 space itself. They’ve always been here—what brings them back to life is always someone with a story to tell.
