Ryokeiji Temple used to be located in Hachiohji Hill near Oshida, and belonged to Tendai School. However, it was burnt down (perhaps by war flames) and moved to the present site Oshida more than 400 years ago. Actually the temple long owned a few lots of land in Hachiohji Hill until the hill was demolished and leveled down to become a residential area． ,
The temple priest Jonen at that time was converted to Shin Buddhism by
Ven. Zensho, 12th chief abbot of Goshoji Main Temple at Gobuichi (4km from
Oshida) and was given a scroll of Namuamidabutsu (right-hand picture),
which has been preserved as a temple treasure.
He also changed part of his name then; the first character was changed from short “Jo” meaing Help to long "Jo" meaning Pure which implies Pure Land. Therefore the Dharma names of all the descending generations begin with “Jo.”
The 10th temple priest Jo'en, who was born in Hirabayashi, a village 2km from Gobuichi, was a disciple of Ven. Zensho, 20th chief abbot of Goshoji and was appointed to preside Ryokeiji. He built the present temple hall.
The 11th generation Joken is said to have traced his descent from Ven. Zensho. Thus the present temple family is of lineage from Goshoji.
The 12th generation Josen was a priest of deep shinjin (faith) and his Dharma words were cherished by his followers.
Ven. Zenge, 24th chief abbot of Goshoji honorably brush-wrote Josen's Dharma phrase as follows:
"You should say the Nembutsu, since this is Amida Buddha's Original Vow. In this, every arrangement is done to save you. Believing in this is defined as entrusting yourselves to Amida Buddha."
The 13th generation Jokan was a scholar and obtained The Taisho Great Collection of Sutras and other valuable Buddhist works, which are now stored in the sutra house named "Fukanzo" after his Ingo title "Fukan-in."
The 14th generation Joshin had a shorter period of activity as he was
killed in the war at the age of 39.
