Sengaku-ji Temple was founded by Tokugawa Ieyasu. It was destroyed by the great fire in 1641 (the eighteenth year of Kan'ei) and relocated to Takanawa and it was five daimyo (Mori, Asano, Kutsuki, Niwa and Mizutani) that worked hard for the relocation of the temple. A stone pagoda was built there for Asano Takuminokami Naganori and his masterless, 47 ex-Akō retainers, who was involved in the Ako Incident.
