Yakatabune

Speaking of Hita's night-time river is a 「Yakatabune」.
Yakatabune is a kind of Japanese style ship.　I enjoy having banquets and meals on board.
While feeling the river's breeze, enjoying alcohol and cooking will be a temporary time of bliss to heal the tiredness of the trip.
Also, if you are lucky you may be able to see the "Ukai" traditional Japanese fishing method
(Ukai is a fishing method that captures fish by manipulating multiple birds)
Why do not you try getting on board once?
