It depends on the food but almost every Japanese food need chopsticks. However, if you ask the restaurant, they may have folks, knives, and spoons.
Below are examples of Japanese food that do not need chopsticks:
- sushi (it is okay to use your hands to eat sushi)
- onigiri (rice ball)
- street food such as taiyaki
- wagashi (Japanese sweets, we usually use a tool like toothpicks)
- curry rice (eaten with a spoon)
