# Thirteen Buddhas

The Thirteen Buddhas (十三仏, Jūsanbutsu) is a Japanese grouping of Buddhist deities, particularly in the Shingon and Tendai sects of Buddhism. The deities are, in fact, not only Buddhas, but also include bodhisattvas. In Shingon services, lay followers recite a devotional mantra to each figure, though in Shingon practice, disciples will typically devote themselves to only one, depending on what the teacher assigns. The chanting of the mantras of the Thirteen Buddhas is a basic practice followed by Shingon and Tendai lay followers. They are also important in funeral and apotropaic / protective rituals.

## Funeral rituals

The Thirteen Buddhas are also an important part of a traditional Japanese Buddhist funeral service, with each deity having a corresponding memorial service for the deceased. The names of the thirteen figures are given below in Japanese and Sanskrit and the corresponding date of their service after the death:
* Fudō (Acala), 7th day
* Shaka (Sakyamuni), 14th day
* Monju (Manjushri), 21st day
* Fugen (Samantabhadra), 28th day
* Jizō (Ksitigarbha), 35th day
* Miroku (Maitreya), 42nd day
* Yakushi (Bhaisajyaguru), 49th day
* Kannon (Avalokitesvara), 100th day
* Seishi (Mahasthamaprapta), 1st anniversary
* Amida (Amitabha), 2nd anniversary
* Ashuku (Akshobhya), 6th anniversary
* Dainichi (Vairocana), 12th anniversary
* Kokūzō (Akasagarbha), 32nd anniversary

## Mantras

While the thirteen figures have several mantras associated to each respectively, those listed below pertain to the standard formula used in Japanese ritual. The Shingon and Tendai schools each use a different method of transliteration of the original Sanskrit. Bhaisajyaguru is the only figure whose mantra fundamentally differs between traditions.
