What is Japan without sushi or (in the case of me, a poor student) kaiten or conveyor belt sushi, where you pick your favorite portions as they come from the kitchen. In case you are lucky enough to be dining with a Japanese-savvy person, you can also order items from the menu, and they will be delivered to your table. Even though your nihongo is not that strong, pointing at the sushi plate pictures is efficient way to get your favorites, too.
In Beppu I have found 2 kaiten sushi places so far, one in You Me town and the other one is where the pictures are from. Unfortunately I have no clue what the name is, but it is located near Beacon Plaza (also known as the diving tower).
Reasons why I like kaiten-sushi:
It is cheaper than going to a sushi restaurant (in Beppu, two pieces of ebi, salmon, unagi and other more common nigiri cost 105y, as well as most of the gunkan-maki and 4 pcs of maki. More expensive sushi are approx. 300y, which is around 3€)
It is fun to watch the conveyor belt and different kinds of sushi
You can eat various kinds of sushi, as much as you want (which can lead to an unpleasant surprise as the plates keep on piling up)
Unlimited green tea, gari (pickled ginger) and wasabi
