If you want to feel intuitively, you can watch Japanese dramas. Recommend "Food Detective King" starring Dongshan. There are two movies in total, and each episode introduces very delicious Japanese food. Lively and fragrant, most of them are eaten every day, which is very convenient to eat and the price is not high. I will also introduce some common sense of food and cooking. More practical.
As for sushi, personally, rolling sushi is better than holding sushi. You can watch the sushi prince starring KOICHI DOMOTO.
