A cooking experience of Japanese dishes

Have you made a rice ball called 'Onigiri'? It is like sandwiches in Western countries, a popular food in Japan.
You put a pickled plum and salted salmon in the center of 'Onigiri' and wrap it with a dried seaweed sheet, 'Nori'. Also, you can eat a Japanese omelet and clear soup made from dried bonito and soy sauce.
