Kobo Daishi, Kukai (774–835), brought the orthodox transmission of esoteric Buddhism from Tang China and founded the Shingon school in Japan. He entered meditation at Mount Koya in 835, and in the Shingon school he is revered as remaining even now in deep meditation at the Okunoin, watching over us.
A memorial (onki) is a great rite held every fifty years. The year 2034 marks 1,200 years since the Daishi entered meditation. A 1,200th memorial comes but once in many generations: an occasion to honour the Daishi’s virtue, and to carry his teaching and his temple to the next generation.
In recent years, several anniversaries connected with the Daishi have come in succession: the 1,200th year of the founding of Mount Koya (2015), and the 1,250th year of his birth (2023). Yet where these celebrate a founding or a birth, the memorial is of another kind. It is the great rite of gratitude offered to the Daishi, who remains even now in meditation at the Okunoin. Held once in fifty years with the whole strength of the school, it is the most revered of all, the foremost observance of Shingon.
Toward this great juncture, Byodoji is restoring its precinct as a single undertaking.
