Onigiri
Hand-pressed rice balls wrapped in nori, often hiding a piece of salted salmon, pickled plum, or bonito flakes — Japan's portable lunch for twelve centuries.
Salt on the hands, not in the rice.
Onigiri is shaped by hand from still-warm rice, palms wetted with salt water. The salt seasons the surface of the ball where it meets the eater's lips; the inside stays plain rice. This is what makes onigiri taste cleaner than a salted-rice ball — the salt is a frame, not a filling.

Onigiri
Hand-pressed rice balls wrapped in nori, often hiding a piece of salted salmon, pickled plum, or bonito flakes — Japan's portable lunch for twelve centuries.
The dish older than sushi. Onigiri (also omusubi) appears in 8th-century Japanese texts — Heian-period nobles took rice balls on travels, samurai armies carried them as field rations, and farming households packed them for working in the fields. The shape, the salt-seasoning, and the nori wrapper have been stable for over a thousand years. Modern convenience-store onigiri is the latest iteration of one of the oldest continuously-made dishes in the Japanese repertoire.
The fillings are a small atlas of Japanese seasoning. Umeboshi — pickled red plum — is the conservative choice and the longest-keeping filling (the salt and acid in the plum function as preservation). Okaka — bonito flakes with a splash of soy — is the umami choice. Sake (grilled salted salmon flaked into pieces) is the everyday choice. Tuna mayo and spicy cod roe are modern additions.
Triangle, round, or cylinder.
The Tokyo default is the triangle (*sankaku*) — the shape pressed into the hand against the thumb, optimised for stacking. Round (*tawara* or *taru*) is the Kyoto tradition. Cylinder (*omochi*) is rarer, more often in rural areas. Each works; the triangle is what every Japanese 7-Eleven cooler stocks.
