How many people fit on a Hozugawa River boat?
What "leaves when full" actually means
On main-season weekends and holidays there is no hourly clock. The pier loads a boat, and when that boat is full it goes. In practice you queue, you are pointed at a boat, and you sit where there is room on the bench. On weekdays the hourly departures between 09:00 and 15:00 run regardless, so a quiet Tuesday boat can be noticeably emptier than a Sunday one. The season timetable is on the timetable page.
Groups, and having the boat to yourself
Groups of nine or fewer can book online. Ten or more are asked to phone ahead, which is the clearest signal that ten is where a party stops fitting neatly into the normal loading. If you want the boat itself, a private charter runs ¥144,000 to ¥162,000 depending on the season. That is the whole boat, not a per-person fare, and it is the only way to control who is sitting next to you. There are also small-group tour days on the water, though that listing is recent enough, and thin enough on history, that I would call it untested. Both routes are laid out on private tours and charter boats.
If sharing a bench with strangers for a hundred minutes is the sticking point, look at a small-group tour before you look at a charter. The price gap between them is enormous, and the boat is the same boat.
Frequently asked questions
How many passengers are on a Hozugawa boat?
The operator does not publish a fixed figure and I am not going to invent one. The boats are shared, the seating is bench style, and on weekends they leave when full.
How many boatmen are there?
Three to five per boat. They swap between the bamboo pole, the oars and the rudder as the water changes. See what to expect on board.
Can I book a whole boat?
Yes, as a private charter at ¥144,000 to ¥162,000 depending on season. Details on the private tours page.
