Naito Togarashi × NIGICHA "Edo Sweet & Spicy Cheese Musubi"

"Edo Sweet & Spicy Cheese Musubi" was born from a collaboration between Shinjuku's own "Naito Togarashi" and NIGICHA. Edo sweet miso from "Abumata Miso" in Nakano, Tokyo is paired with Kiri® cream cheese and finished with walnuts. The spicy kick of Naito Togarashi, the gentle sweetness of Edo sweet miso and the mellow richness of cream cheese are accented by the aroma and texture of walnuts, creating an onigiri with real depth of flavor. Following its warm reception at the Shinjuku Gyoen 120th anniversary event, it is now on sale at our Shinjuku Gyoenmae store, and is also entered in the "Gotochi Onigiri Grand Prix 2026." Edo flavors, in today's onigiri. Please enjoy this onigiri that combines Shinjuku's food culture with NIGICHA's fresh ideas.
