Is it true that is a no-no in japan to pick up your rice or miso soup bowl and hold under chin keep stuff from falling?

In formal settings, it's considered rude to pick up your rice bowl. The proper way to eat rice in Japan is to use chopsticks to take small bites and leave some rice in the bowl.

Holding the bowl under your chin to prevent spills is considered even ruder. It's seen as messy and unrefined.

However, in casual settings, especially at home or with close friends, it's perfectly acceptable to pick up your rice bowl. It's seen as a more efficient way to eat, especially for larger portions.

Regarding miso soup, it's generally not considered rude to hold the bowl. You can pick it up and drink the soup directly from the bowl. However, be mindful of slurping, which is generally considered rude in Japan.

In short, whether holding your rice bowl is acceptable depends on the setting and the people you're dining with. It's always best to err on the side of caution in formal settings and avoid holding the bowl.
