As autumn arrives with the evening breeze, it gently makes its presence known. The cool, tranquil climate of autumn is perfect for heading to the Kii Peninsula in southern Kansai, Japan. Immerse yourself in the breathtaking sea views and natural cave hot springs crafted by nature, while also visiting World Heritage sites. Slowly savor the beauty of Japan’s nature and architecture.

Indulge in Imperial-Style Hot Springs at Shima Onsen Urashima Hotel

Located in Shirahama Bay along the southern coast of the Kii Peninsula in Nachikatsuura Town, southeastern Wakayama Prefecture, Shima Onsen is one of Wakayama’s most representative hot spring resorts, with numerous hot spring hotels in the area. Among them, the Urashima Onsen Hotel, which blends Western and traditional Japanese hotel styles, features six unique types of hot spring baths, including the famous “Oami-no-Yu” cave hot spring. Formed naturally by years of erosion from wind and waves, this open-air hot spring faces the Pacific Ocean, offering sweeping views of the vast sea. While soaking, you can enjoy the gentle sound of flowing hot spring water accompanied by the powerful roar of ocean waves—like listening to a symphony—making for an incredibly relaxing natural spa experience.

Pilgrimage to the World Heritage Kumano Ancient Trail for a Touch of Nostalgia

The Kumano Sanzan includes three grand shrines: Kumano Hongu Taisha, Kumano Hayatama Taisha, and Kumano Nachi Taisha. This region is often described as a spiritually rich and slightly mysterious place, revered by the Japanese as a “sacred land where the gods reside.” Since the 10th century, both Japanese royalty and commoners have come here to worship. The Kumano Ancient Trail is the mountain path that leads to this earthly paradise, often referred to as the “Ant Pilgrimage to Kumano” due to the endless streams of visitors.

This over 1,200-year-old sacred site masterfully blends traditional Japanese Shinto and Buddhism, preserving the long-standing spiritual traditions of these sacred mountains. In 2004, it was inscribed as one of only two pilgrimage routes listed as UNESCO World Heritage Sites. Walking along this ancient trail, sunlight filters through ancient trees, as if divine light is descending, purifying both the soul and the noise of the world.

Enjoy Maple Leaves and Unique Rocks on a Pichi Gorge Boat Cruise

The Pichi Gorge, a 31-kilometer-long tributary of the Kumano River within the Yoshino-Kumano National Park, is a valley formed by the erosion of slate and sandstone by river water. Taking a boat ride through this area and immersing oneself in the wilderness is a truly delightful experience. Especially captivating is the lower section of the gorge, also known as Pichi Hachicho, which has been designated as a national natural monument. Stretching about 1.2 kilometers, the canyon features steep cliffs on both sides, with massive rocks and peculiar stones lining the area. Along the way, you’ll encounter unique sights such as the “Donten Gate,” “Husband and Wife Rocks,” “Turtle Rock,” “Folding Screen Rock,” “Cold Spring Cave,” “Falling Rock,” “Heavenly Pillar Rock,” “Tosaka Rock” (cock’s comb), “Daikoku Rock,” and “Cold Jade Drift.” Looking up, you’ll see rugged cliffs and oddly shaped rocks; looking down, you’ll see the blue flowing waters. The scenery of the gorge is incredibly diverse. Especially during the autumn foliage season, the canyon is painted in vibrant reds by various maple trees, creating a breathtaking spectacle.

Kongobuji Temple on Mount Koya: A Sacred Site for Spiritual Cultivation

In the 9th century, Kobo Daishi (Kukai) obtained permission from Emperor Kanmu to travel to Chang’an (modern-day Xi’an), China, to study Buddhism. Two years later, upon returning to Japan, he actively sought a place to carry out his activities and spiritual practice. The Kii Mountain Range, located around 1,000 meters above sea level in Koya Town, Ito District, Wakayama Prefecture, resembled a lotus petal encircled by eight peaks—an ideal location. He requested Emperor Saga to designate it as the head temple of Shingon Buddhism. Kongobuji Temple is the head temple of the Koyasan Shingon sect, and many other temples were built around it. Later, it became part of the “Sacred Sites and Pilgrimage Routes in the Kii Mountain Range,” registered as a UNESCO World Heritage Site.

The current Kongobuji Temple complex was formed in 1869 through the merger of two temples: Seiganji and Ankokuji. Seiganji was built by Toyotomi Hideyoshi in memory of his deceased mother. Among its structures, the Fudō Hall, dedicated to Fudō Myōō (the Immovable One), was constructed by one of Emperor Toba’s consorts. With its uniquely feminine and elegant design, it is the oldest building in the temple complex and has been designated as a national treasure. Another distinctive feature of Kongobuji Temple’s architecture is the placement of rainwater barrels on the eaves of the Hinoki-bark-roofed building. These barrels not only store rainwater but can also help suppress fires in case of emergencies, showcasing the ingenuity and thoughtfulness of its designers.

Whether for soaking in hot springs, admiring spectacular scenery, or spiritual rejuvenation, the Kii Peninsula in southern Kansai is always an excellent choice.
