Shimai Soshitsu, a wealthy Hakata merchant and tea master, lived at this residence. On June 2, 1582, he was staying at Honno-ji Temple, having been invited to a tea gathering hosted by Oda Nobunaga. That very night, Akechi Mitsuhide's rebellion erupted—the Honno-ji Incident. Soshitsu escaped carrying a calligraphy scroll by Kukai, becoming a rare witness to Nobunaga's final night.
