Sawara Historic District

**Boat ride:** Small wooden boats (sappa-bune) run 30-minute cruises on the Ono River, departing every 30 minutes from 10:00-16:00 at the Ino Tadataka Museum dock (¥1,500). The narration is Japanese-only but the visuals are the point: passing under willow branches, ducking beneath 300-year-old stone bridges, gliding past machiya with wooden docks where merchants used to load rice onto boats. Early morning (10:00) and late afternoon (15:00) give you the best reflections on the water. Skip it if the river looks muddy after rain. **Ino Tadataka's house:** Sawara's most famous resident, Ino Tadataka (1745-1818), spent 17 years walking the entire coast of Japan to create the first accurate national map. His former residence is now a museum showing his surveying tools — wooden quadrants, measuring chains, star charts — and the massive hand-drawn maps he produced. His measurements were accurate to within 0.2%, using nothing but Edo-period instruments and patient triangulation. The precision is staggering. Entry ¥500, combined with the boat dock. **Sake brewery:** Terada Honke has been brewing since 1673, and they still use kimoto fermentation — the traditional method where wild yeast ferments the rice naturally instead of adding commercial yeast. The result is earthy, funky sake with more complexity than modern styles. Tastings cost ¥500 for five small cups poured in their Edo-period kura warehouse. Their Gonin Musume junmai is the flagship bottle (¥2,500 for 720ml), sold only at the brewery and specialist Tokyo shops. The building itself is worth seeing: massive wooden beams, clay walls, dim lighting, the smell of fermenting rice. **Festival timing:** The Sawara Grand Festival runs twice yearly: July 14-16 (Yasaka Shrine) and October 12-14 (Suwa Shrine). Massive three-story wooden floats (dashi) get pulled through the narrow streets by teams of 50+ people, accompanied by flutes and drums. The floats carry mechanical ningyo dolls that move their heads and arms — Edo-period animatronics powered by hidden pulleys. The procession dates to 1700 and hasn't changed much since. Streets are packed; arrive early for viewing positions.
