Located in Wakayama Prefecture, Mount Koya (Koyasan) boasts a history of more than 1,200 years. This sacred religious town, surrounded by tranquility and a mystical atmosphere, is one of the destinations you should definitely consider visiting while traveling in Osaka or Kyoto.

In this article, we will introduce Mount Koya, where nature and spiritual devotion exist in harmony, allowing visitors to experience the depth of Japanese culture.

Koyasan was founded in 816 by the Buddhist monk Kukai, also known as Kobo Daishi, as the sacred center of Shingon Buddhism. It is located on a mountain basin at an elevation of about 800 meters in the northeastern part of Wakayama Prefecture.

Today, the area is home to 117 temples, around 50 of which welcome visitors for overnight stays and temple experiences. In 2004, Koyasan was registered as part of the Sacred Sites and Pilgrimage Routes in the Kii Mountain Range, attracting many visitors from across Japan and around the world.

Because Koyasan is located at a high elevation, temperatures are usually 5–10°C lower than in lowland cities such as Osaka. Summers are pleasantly cool, while winters can become very cold, with snow sometimes accumulating.

Recommended Clothing and Items

■ Comfortable walking shoes
There are many gravel paths and stone-paved roads, so sneakers are the best choice. From late December to late February, snow may accumulate, so shoes with good grip are recommended.

■ Warm clothing or a light jacket
Even in summer, mornings and evenings can be chilly, so bringing a light jacket you can easily put on is a good idea. In winter, be sure to dress warmly.

■ Rain gear
Mountain weather can change quickly, so carrying a folding umbrella is recommended.

Although Koyasan is so vast that it’s impossible to see everything in a single day, here are some must-visit spots that are especially recommended for a day trip or a one-night stay.

This is the most sacred site in Koyasan, where Kukai is believed to continue meditating even today. Along the approximately 2-km approach stand towering cedar trees that are hundreds to over a thousand years old. About 200,000 gravestones, memorials, and monuments—including those of famous feudal lords—line the path, creating a deeply spiritual atmosphere.

Estimated visit time:

• About 1.5–2 hours on foot from Ichinohashi Bus Stop
• About 1 hour on foot from Okunoin Bus Stop

Standing at the entrance to Koyasan, this massive vermilion gate is 25.1 meters tall. It was rebuilt in 1705 after being destroyed by fires and lightning strikes. The powerful Niō guardian statues standing on each side are truly impressive. The sunset viewed from Daimon Gate is also known as one of the most beautiful sights in Koyasan.

Estimated visit time: about 10–15 minutes

This temple complex was the first place developed by Kukai when he established Koyasan and remains the spiritual center of Shingon Buddhism. Located near the center of Koyasan, it is packed with highlights such as Kondo Hall, the main hall of Koyasan; Konpon Daito, a striking vermilion pagoda symbolizing esoteric Buddhism; and Miedo Hall, where Kobo Daishi once lived.

Estimated visit time: about 30–40 minutes

Located near the center of Koyasan, this temple serves as the head temple of the Koyasan Shingon sect, overseeing the administration of the entire complex. It is about a 5-minute walk from Danjo Garan. The temple is also home to one of Japan’s largest rock gardens, whose scale and beauty are truly breathtaking.

Estimated visit time: about 30–45 minutes

Situated at the foot of Koyasan, this temple is believed to be where Kukai’s mother once stayed. It has long been popular with female worshippers and is known for prayers related to safe childbirth and nursing.

Estimated visit time: about 20–30 minutes

If you visit Koyasan, one experience you should definitely try is staying at a temple lodging (shukubo). Shukubo are accommodations originally created for monks and pilgrims. Guests can enjoy traditional Buddhist vegetarian cuisine and experience aspects of temple life such as morning prayers, sutra copying, and meditation.However, since shukubo operate differently from regular hotels, it’s important to keep the following points in mind:

■ Morning prayers (Gongyo)
Around 6:00 a.m., a Buddhist chanting ceremony takes place. Participation—such as listening to the sutra chanting or offering incense—is often optional, but joining is highly recommended to start your day in a peaceful atmosphere.

■ Facilities
Because many temples are historic buildings, toilets and baths may be shared rather than located inside guest rooms. Recently, more shukubo offer private facilities, but it’s best to confirm when making your reservation.

■ Meals
Meals typically consist of shojin ryori, a traditional Buddhist cuisine that does not use meat or fish. The dishes highlight vegetables, tofu, and other plant-based ingredients, offering delicate and refined flavors.

■ Curfew and lights-out
Many temple lodgings have a curfew (usually around 9:00 p.m.) and set bathing hours.

Although there are special rules, they are part of what makes staying at a shukubo so unique. Spending a night surrounded by the calm and dignified atmosphere of the temple will surely become an unforgettable experience.

The pure air at an elevation of about 800 meters, the striking colors of Danjo Garan, and the deep tranquility of Okunoin—Koyasan offers a truly extraordinary experience that you should not miss.

In particular, staying at a temple lodging provides a kind of “luxury for the soul” that is quite different from the convenience of a hotel. The delicious cuisine, a traditional Buddhist cuisine made without meat or fish, and the crisp, solemn atmosphere of the early morning prayers create a deeply memorable experience unlike everyday life.
