My husband is interesting in Chushingura.
He wanted to go to Sengaku-ji.
Chūshingura is the name for fictionalized accounts of the historical revenge by the Forty-seven Ronin of the death of their master, Asano Naganori. Including the early Kanadehon Chūshingura, the story has been told in kabuki, bunraku, stage plays, films, novels, television shows and other media. With ten different television productions in the years 1997–2007 alone, the Chūshingura ranks among the most familiar of all stories in Japan.
Sengakuji is a Soto Zen Buddhist temple located in the Takanawa neighborhood of Minato-ku, near Shinagawa Station, Tokyo, Japan.
The graves of Asano Takumi no Kami Naganori and the Forty-seven Ronin are there.
