Hidden among the cedar-covered mountains of Wakayama Prefecture, Koyasan (Mt. Koya) is one of Japan’s most fascinating spiritual destinations. Home to over 100 temples, ancient pilgrimage routes, and the sacred resting place of Kobo Daishi, the founder of Shingon Buddhism, Koyasan offers visitors a chance to experience a quieter and more traditional side of Japan.
Located approximately 800 metres above sea level, the temple town has served as an important religious centre for more than 1,200 years. Today, visitors can stay overnight in Buddhist temples, enjoy traditional vegetarian cuisine, explore centuries-old religious sites, and walk through one of Japan’s most atmospheric cemeteries.
Part of the UNESCO-listed Sacred Sites and Pilgrimage Routes in the Kii Mountain Range, Koyasan remains an active place of worship while welcoming travellers from around the world.

Things to Do in Koyasan
Most visitors spend their time exploring temples, walking through forested paths, attending Buddhist ceremonies, and enjoying the peaceful mountain atmosphere.
Okunoin Cemetery: The Most Important Site in Koyasan
The most famous and spiritually significant site in Koyasan is Okunoin Cemetery.
Stretching for approximately two kilometres through a cedar forest, it is Japan’s largest cemetery and contains more than 200,000 graves and memorials. As you walk along the stone pathway, you will pass monuments belonging to samurai families, feudal lords, monks, and even modern corporations.
The atmosphere is remarkably peaceful, particularly in the early morning and evening.
At the end of the path lies the mausoleum of Kobo Daishi. Followers believe that he remains in eternal meditation rather than having died. Before reaching the mausoleum, visitors cross Gobyo Bridge, where photography, eating, and drinking are prohibited out of respect.
Nearby is the Torodo, or Hall of Lanterns, where thousands of lanterns illuminate the darkness. Some are believed to have been burning continuously for centuries.
Kongobu-ji Temple
Kongobu-ji serves as the head temple of Shingon Buddhism and is one of Koyasan’s most important religious sites.
Visitors can explore beautifully preserved temple rooms decorated with painted sliding doors depicting scenes from nature. The temple’s peaceful atmosphere provides an excellent introduction to the aesthetics of Japanese Buddhism.
One of the highlights is the Banryutei Rock Garden, the largest rock garden in Japan. Its carefully arranged stones are said to represent dragons emerging from clouds.
Danjo Garan
Danjo Garan is considered the spiritual heart of Koyasan and was among the first temple complexes established by Kobo Daishi.
The most recognisable structure is the striking Konpon Daito, a large vermilion pagoda that symbolises the central teachings of Shingon Buddhism. Nearby stands the Kondo Hall, where many important religious ceremonies are held.
The layout of Danjo Garan reflects Kobo Daishi’s original vision for Koyasan as a sacred centre for Buddhist learning and practice.
Daimon Gate
The impressive Daimon Gate marks the traditional entrance to Koyasan.
Standing approximately 25 metres tall, it forms a symbolic boundary between the sacred mountain and the outside world. Two imposing guardian statues stand within the gate, protecting the temple town from evil spirits.
The area around Daimon also offers some of the best views in Koyasan, especially around sunset.
Reihokan Museum
For those interested in Buddhist art and history, the Reihokan Museum is well worth a visit.
Its collection includes Buddhist statues, paintings, mandalas, and religious artefacts gathered from temples throughout Koyasan. Many of these pieces are designated cultural treasures and provide valuable insight into the history of Shingon Buddhism.
Tokugawa Mausoleum
Often overlooked by visitors, the Tokugawa Mausoleum honours Tokugawa Ieyasu and his son Tokugawa Hidetada.
The ornate carvings and decorative architecture differ noticeably from the simpler style found elsewhere in Koyasan, making it a fascinating stop for history enthusiasts.
Staying at a Temple (Shukubo)
One of the most memorable experiences in Koyasan is staying overnight in a temple, known as a shukubo.
Around 50 temples offer accommodation to visitors, providing a unique opportunity to experience daily life within a Buddhist temple community.
A typical stay includes:
- Traditional tatami room
- Futon bedding
- Shared bathing facilities
- Shojin ryori dinner and breakfast
- Access to temple grounds
- Morning prayer ceremonies
Many temples also offer cultural activities such as:
- Ajikan meditation
- Sutra copying (shakyo)
- Guided temple tours
Participation is usually optional, although attending the morning prayers is highly recommended.
Popular temples for visitors include:
Staying overnight allows you to experience Koyasan after most day-trippers have departed, creating a much quieter and more atmospheric experience.
What to Eat in Koyasan
Shojin Ryori
Koyasan is famous for shojin ryori, the vegetarian cuisine traditionally eaten by Buddhist monks.
Rather than relying on meat or fish, the dishes focus on seasonal vegetables, tofu, mountain plants, and carefully balanced flavours.
Common dishes include:
- Sesame tofu (goma dofu)
- Seasonal vegetable tempura
- Simmered mountain vegetables
- Miso-based dishes
- Pickled vegetables
Goma dofu is considered a local speciality and is one of the foods most associated with Koyasan.
Even visitors who are not vegetarian are often impressed by the quality and variety of the cuisine.
Hiking to Koyasan
Choishi Michi Pilgrimage Trail
Long before railways reached Koyasan, pilgrims travelled on foot using mountain routes leading to the sacred site.
The most famous of these is the Choishi Michi Trail, a historic pilgrimage route beginning near Kudoyama.
The trail stretches approximately 22 kilometres and follows a series of stone markers known as choishi, which guided pilgrims to Koyasan for centuries.
Today, the trail offers hikers a rewarding way to experience both the natural beauty and religious history of the region.
