Onigiri, which is inevitably sold out, is "Salt Musubi" without ingredients- "Tsukiji Aji Kitakai"
What do you like about rice balls? There are a wide variety of plums, cod roe, cod roe, and so on, but the only way to truly enjoy the deliciousness of rice is with salted cod roe! I tried the salted musubi, which is inevitably sold out at "Tsukiji Aji Kitakai".
