A “Yakata bune” is a type of Japanese boat that is mainly used for banquet parties and meals on board, and features a roof and seating area.

The meals offered on a yakata bune are not only Japanese, but also Western food, monja-yaki, Barbecue that is also popular with children, and so on.
You should be able to find a meal that suits your tastes.
The seating is also not limited to just tatami rooms, so if your feet hurt from sitting on tatami for a long period of time, sunken kotatsu rooms or conventional table seating may be preferable.

There are a few things to keep in mind to further enhance your enjoyment.
While you can surely already imagine there will be good food, good drinks, and beautiful seasonal scenery, there is also karaoke.
Karaoke performed in an unusual, special atmosphere will surely be fun.
Why not take the opportunity to sing one of the songs you can perform best?

It is a basic rule, but be sure to be on time for the departure. For a yakata bune, all passengers are boarding the same boat, so just one person being late can delay the departure time for everyone.

It is also a good idea to pay attention to your outfit. High heels or other slippery shoes are not a good idea, since you will be sailing close to water. Also, the wind can be stronger than you’d expect, so skirts that billow easily could be a problem.

You might worry if there is a toilet or not, but relax- yakata bune generally are equipped with toilet facilities, so even if you find yourself drinking a lot, it isn’t a problem.

Besides the above, all that’s left is to be sure to enjoy yourself.
And be careful not to drink too much!
