At the site of Ryogen's old residence, called Joshinbo, in Yokawa on Mt. Hiei, there is a Shiki Kodo (Four Seasons Lecture Hall) (it is so named because a lecture of Hoke-kyo Sutra (Lotus Sutra) was conducted at this hall once every four seasons) and it is called 'Gansandaishi-do' as Ryogen's image is enshrined in it.
比叡山横川（よかわ）にあった良源の住房・定心房跡には四季講堂（春夏秋冬に法華経の講義を行ったことからこの名がある）が建ち、良源像を祀ることから「元三大師堂」とも呼ばれている。
