A 10-minute walk north of Kumamoto Castle, this 300-year-old samurai mansion was built by a subsidiary member of the Hosokawa clan, Lord Gyobu, and was enlarged in the 1800s. Guided tours (often available in English) lasting 15 minutes take visitors through 24 rooms, including the lord's study and reception room, teahouse, kitchen, and servants' quarters. You'll see Edo-Era furnishings and personal items including an Edo clock, a suitcase, clothing, games, a woman's cosmetic case, lacquerware, a kimono chest, and more, giving you a good idea of how feudal lords lived during the Edo Period.
