Mangan (completion of a vow) (満願)
Mangan refers to completion of the period determined to be spent praying for Shinto or Buddhist deities or to practice asceticism.
It also refers to the final day as in 'the day of Mangan.'
Fulfillment of the wish prayed for Shinto or Buddhist deities is called Mangan joju. The period of the prayer or practice is separated into three parts; Kaibyaku (literally, to start from zero), Chugan (literally, the middle of term of a vow; also called Chunichi) and Kechigan (literally, expiration of term of a vow). The final day of Kechigan is called Mangan.
