On March 11, 2007 when the tourists calmed down, 'Sannan-ki (memorial service for Sannan)' was held to mourn Keisuke SANNAN in the neighborhood of the former Maekawa residence, and a memorial event was held where offering of incense was made in the room where Keisuke SANNAN committed Seppuku.
それら人手も落ち着いた2007年の3月11日、旧前川邸界隈にて山南敬助を弔う「山南忌」が行われ、山南敬助が切腹した一室での焼香などの記念行事が催された。
