Shiruko Sando is a long-running hit from Matsunaga Seika in Nagoya: two thin, crisp biscuits with a layer of shiruko (sweetened azuki red-bean) inside, with a subtle savory edge that keeps it from being too sweet. It's nostalgic, moreish, and one of Nagoya's signature snacks.
At a glance
The 3 flavors in this autumn set
Fresh (Nama) 生しるこサンド
A softer, moister "nama" take — chewier and richer than the crisp original.
Chestnut しるこサンド栗
Autumn chestnut folded into the red-bean filling — nutty and seasonal.
Sweet Potato しるこサンドさつまいも
Mellow roasted-sweet-potato flavor, another autumn favorite.
Why try it
- A genuine Nagoya icon — Shiruko Sando has been a regional staple for decades; this is real local snack culture, not a tourist gimmick.
- Autumn-only flavors — chestnut and sweet potato are seasonal twists you can't get year-round.
- Individually wrapped & shelf-stable — easy to share, gift, and carry; keeps at room temperature.
- Red bean, approachable — a gentle, biscuit-forward intro to Japanese anko (sweet red bean) if you're new to it.
