Japanese etiquette you need to be aware of.
Tatebashi is what it's called when chopsticks are placed in a bowl of rice standing up. In Japanese Buddhist funerals, rice is offered to the deceased with the chopsticks standing straight in the bowl. Since it has this funeral connection, it's also a breach of manners to do it in daily life. When you're eating and you want to put your chopsticks down, please use a chopstick rest.
