What if your next Shinkansen journey started with dessert?

Tokyo Station is always bustling as a major travel hub—but did you know that, in the short moments before boarding the Shinkansen, you can pick up the perfect companion for your journey?

On the Shinkansen platforms for Lines 20 and 21, right next to the ekiben shop, stands a bright yellow frozen sweets vending machine. Inside, you’ll find Komeko Roll, a rice flour roll cake delivered directly from Tokamachi City in Niigata Prefecture.

Experience the evolution of Japanese sweets!
The first-ever frozen Komeko Roll (Rice Flour Roll Cake) vending machine has arrived at Tokyo Station’s Shinkansen Platforms 20 and 21.

*Premium Quality
Made with 100% Uonuma Koshikari rice flour from Niigata, Komeko Roll is a delicious choice for those pursuing a gluten‑free lifestyle.

*Fully Cashless
No coins?
No problem. Simply tap your IC card or smartphone (Suica, etc.) for a seamless purchase.

*Frozen Delight
Enjoy it right away like an ice‑cream cake, or let it thaw into a fluffy masterpiece during your ride.

Since the cake is dispensed frozen, it’s a little firm right after purchase—but that’s all part of the plan.
As you settle into your seat on the Shinkansen and pick up a freshly brewed coffee from the nearby BECK’S COFFEE vending machine, the cake slowly begins to thaw, reaching its ideal texture just in time to enjoy.

Komeko Roll is a unique frozen dessert that changes in texture and flavor depending on when you eat it.
Perfect for enjoying during your Shinkansen journey—choose your favorite moment and style.
