Top Attractions at Mount Koya

Kōyasan is the center of the Shingon school of Buddhism, founded by Kōbō Daishi (also known as Kūkai), who built the main temple, Kongōbu-ji, at the summit of Kōyasan.

He later established the Garan temple complex, which has since developed into over 100 temples. Among these, the most significant are the main temple, Kongōbu-ji, and the mausoleum of Kōbō Daishi located in the sacred site of Okunoin.

Kongobu-ji: the Head Monastery on Kōyasan

Kongobu-ji is a site for important religious ceremonies and rituals. The main hall features exquisite screens painted in the 16th century.

There, you could learn about Kōbō Daishi's experiences in China and the story of how Kōyasan was established.

You should not miss one of the largest Japanese rock gardens in the temple, which combines Zen philosophy with natural aesthetics, making it an excellent place for quiet reflection and meditation.

Okunoin Temple: a Walk-Through Spiritual Journey

Okunoin Temple is home to over 200,000 graves, including those of Kōbō Daishi and other notable figures from Japanese history, such as samurai and nobility. It is one of Japan's three major sacred sites.

You could walk along the 2-kilometer (1 mile) pilgrimage path, which is flanked by ancient cedar trees and illuminated by countless lanterns at dusk, along with hundreds of stone lanterns and statues. Monks chant softly in the evening.

An important daily ceremony occurs at 6am and 10:30am at Gōbyō Bridge, where monks recite sutras and offer meals to Kōbō Daishi, a tradition upheld for centuries, regardless of the weather.

Please note that photography is prohibited after crossing Gōbyō Bridge.

Garan: Koyasan' s Central Temple Complex

The two most prominent structures in the temple complex are the Kondo Hall and the massive Konpon Daito Pagoda. The Kondo Hall is a large wooden temple hall primarily used for significant ceremonies, dedicated to the Buddha of Medicine and Healing, Yakushi Nyorai.

Next to the Kondo Hall stands the striking red Konpon Daito Pagoda, a 45-meter (148-foot) tall treasure pagoda, which houses a central statue of Dainichi Nyorai.

If you're interested in Buddhist culture, you shouldn't miss the three-dimensional representation of the Buddhist mandala in the Konpon Daito Pagoda, which showcases the esoteric view of the universe. When illuminated at night, it takes on an even more mysterious ambiance.

Reihokan Museum: a Treasure Trove of Koyasan

The museum's collection contains over a thousand religious artifacts, with permanent exhibitions showcasing Buddhist art, including statues, ritual implements, and scriptures.

Additionally, there are historical artifacts and relics related to the founder, Kobo Daishi (Kukai), providing insights into his life and achievements, along with various other religious tools and paintings.

Top Things to Do on Mount Koya

In the serene and natural surroundings of Mount Koya, you could explore the pilgrimage path, experience daily life as a monk, and savor Buddhist vegetarian cuisine.

1. Experience a Koyasan Temple Stay as a Monk

Staying at a temple is the most recommended experience on Koyasan. You could enjoy shojin ryori (Buddhist vegetarian cuisine) and participate in morning prayers, sutra copying, and Ajikan meditation.

The Koyasan Shukubo Association is the official website of Koyasan, featuring introductions and photos of various temples. Popular choices include Eko-in, Fukuchi-in, and Shojoshin-in.

Prices for temple stays vary depending on the room, meals, and season. Most accommodations do not have air-conditioning but offer heating; during the hotter months, fans are usually provided.

2. Walk on a Pilgrimage Trek in Okunoin

The Okunoin pilgrimage path is worth experiencing. As you walk through the towering cedar trees, you could explore the famous tombstones in detail, immersing yourself in the tranquility and spirit of nature.

Arriving at Gobyō Bridge, you could listen to monks chanting sutras and participate in the Kōbō Daishi's meal offering ceremony, a tradition that has been practiced for over a thousand years.

When you finish the trek in Okunoin, you should walk along the same trail to go back to the entrance of Okunoin and take the bus to return.

3. Enjoy a Night Tour Illuminated by Stone Lanterns

Okunoin hosts nighttime pilgrimage events, where you are guided by monks along the path illuminated by stone lanterns. Immerse yourself in a unique religious atmosphere.

During this approximately 1 to 1½-hour experience, you would learn about Shingon Buddhism, basic Buddhist teachings, and captivating stories about Okunoin.

Additionally, this guided tour is the best way to ensure your safety while walking in the mountainous region at night.

For the night tour, it is recommended to join the guided tour at Eko-in, led by a monk who provides in-depth explanations in English.

4. Taste Shojin Ryori (Buddhist Vegetarian Cuisine)

Experience the vegetarian cuisine of Japanese Buddhism by trying shojin ryori, which varies with each temple offering its own unique dishes. This fully vegetarian meal primarily features seasonal fresh vegetables, tofu, seaweed, and rice, allowing you to appreciate the philosophy of Buddhism and the significance of life through food.

Dining etiquette is important, so be sure to follow Japanese table manners and be mindful of the meal times set by the temple's schedule. Reservations are typically required 1–2 days in advance. If you do not wish to stay overnight, you could make a reservation for meals separately.

After November, temperatures gradually drop to just a few degrees. There is a significant temperature difference between day and night so warm winter clothing is necessary for the early mornings and evenings.

Visiting Mount Koya in Winter

Winter brings cold temperatures but the snow-covered temples and forests are incredibly serene and worth experiencing mindfully.

Hanabishi

• Address: Koyasan 769, Koya-cho, Ito-gun, Wakayama Prefecture

Tonkatsu-tei

• Address: Koyasan 49-48, Koya-cho, Ito-gun, Wakayama Prefecture

Is Mount Koya Worth Visiting?

If you're looking for self-discovery, inner peace, or a break from life's pressures, staying at a temple on Mount Kōya could be a meaningful experience.

However, this journey needs careful thought: the remote location means a long travel time and the temple accommodations are quite basic compared to similarly priced city hotels.

Meals are strictly vegetarian and winter could be tough — it' s cold since you couldn' t wear shoes inside the temple.

This isn' t a typical tourist trip; it' s more like a spiritual retreat focused on reflection rather than comfort.

Tips for Visiting Mount Koya

• If you plan to join the night tour of Okunoin, consider staying at Eko-in as the tour departs from its entrance, making it convenient to dine and then explore.
• If you stay at other temples, you could take a bus back to their accommodation after the night tour. When selecting a temple for your stay, try to choose one that is located on the main road for easier access to public transport.
• Please note that most temple accommodations do not accept credit cards, so be sure to prepare cash.
