A singing boatman,
then eel in a box.

The canals are pretty. The reason 237 reviewers put this top of everything in Yanagawa is the man with the pole.

A donkobune is a flat wooden punt, poled rather than rowed, carrying a dozen or so passengers low on the water through a moat network the Tachibana clan dug around their castle town. The route runs the 'seven bends, seven turns' from Shimohyakucho toward Ohana, and it takes about an hour. The boatman narrates, jokes and sings folk songs as he works — reviewers describe the hour as stepping back in time, and the trip rates 4.2 on TripAdvisor across 237 reviews, the top-rated thing to do in the town. Nobody complains about the price.

The honest complaints, all real and all survivable: several bridges are low enough that you genuinely have to fold yourself flat as the boat passes under, some stretches of water sit still and green in summer, and heavy rain raises the level enough to disrupt service. Umbrellas are banned on board for obvious reasons; free ponchos are handed out in rain and free sun hats in summer. From 1 December to 28 February the boats run with kotatsu — a heated table under a blanket — which is the single most charming version of this trip and the reason to consider a winter visit.

Timing quirks worth knowing before you commit a date. In February the sluices are lowered for maintenance, which forces the shortened U-turn course at ¥1,800 / ¥900 (~$12 / $6) and roughly 30 minutes instead of 60. A summer-only route operates July to September. Several operators run near-identical services at near-identical prices, so there is no comparison shopping to do — turn up, buy, board within half an hour.

Yanagawa's dish is unagi seiro-mushi: eel grilled over charcoal, laid on rice already seasoned with the sauce, then the whole bamboo box steamed so the flavour goes all the way down. It is not the Tokyo kabayaki you may have had — the rice is the point as much as the fish. The two canonical houses are Ganso Motoyoshiya, founded in 1681, and Wakamatsuya; Tsugumi, Fuji-ya and Tanaka are the everyday alternatives. Expect roughly ¥3,000–5,000 (~$20–33) for a set, with premium and large portions pushing past ¥6,000 (~$40).

Every price on this page was checked in early August 2026 against official or primary sources. Japanese attraction prices move and English sources go stale fast; where we couldn't verify a number, we say so instead of guessing.

On that last point, plainly: the eel houses publish menus on paper and on their walls, not on the open web, so treat the ¥3,000–5,000 band as the market rate rather than a quoted price. Nishitetsu also sells a 'Yanagawa Tokumori' ticket bundling rail, the boat and an eel meal — we could not confirm its 2026 price, so we're not printing one. Ask at the Nishitetsu Tenjin ticket counter; if it's running at a sane number it's the one-transaction answer to the whole day.

The queue is real: 11:30 to 13:30 is when every boat that launched at 10:00 arrives hungry at the same six restaurants. Eat at 11:00 before your boat or after 14:00 following it, and you'll walk in. While you're waiting, Ohana — the Tachibana family villa with a Meiji-era Western wing and the Shoto-en pine-and-pond garden, a designated Place of Scenic Beauty — is the sensible filler at around ¥1,000 (~$6.65), a figure worth confirming at the gate.
