Iwase: the Kitamae-bune street岩瀬・北前船の廻船問屋街
Iwase was the port that sent rice and sake north and brought kelp home on the Kitamae-bune merchant ships, and the shipping agents' street still stands: long narrow plots, deep eaves, storehouses behind. Walking it takes 20–30 minutes. Baba House 旧馬場家住宅 costs ¥100 (9:00–17:00, last entry 16:30, cash only), and the Mori house is closed for earthquake repairs until at least fiscal 2027.
Saseki 沙石, the standing bar of the Masuizumi brewery, opens at 10:00 and closes on Tuesdays; a glass is ¥200–500. The driver should not taste (see Snow and roads), but a bottle of Masuizumi is a good thing to carry home. The lanes are narrow, so leave the car in a car park and walk. More in the Iwase guide.
