Only a limited run of Nama Kuri Mushi Yokan is available at Okashi no Taiyo in Sosa, Chiba. The chestnut-filled steamed yokan returns on October 8, 2026, following strong demand for the shop’s autumn seasonal sweet.
The product will be sold in limited quantities from October 8 until supplies run out at all Okashi no Taiyo stores. Customers can also order it through the shop’s Rakuten online store, with shipping beginning October 8. In-store and telephone reservations are available.
Each yokan uses 13 large chestnuts: eight arranged across the top and the equivalent of five more pieces mixed into the yokan. The store price is ¥2,500 (tax included), while the Rakuten price is ¥3,200 (tax included). The product has a 10-day best-before period.
About Okashi no Taiyo’s Chestnut Yokan
Nama Kuri Mushi Yokan is made with carefully selected large chestnuts simmered in syrup and a steamed yokan base made from smooth red-bean paste. Rather than setting the sweet with the firm texture associated with traditional neriyokan, Okashi no Taiyo slowly steams the mixture in a wooden steamer, creating a moist, chewy texture that pairs with the chestnuts’ soft, crumbly bite.

The dramatic chestnut topping is the first thing customers notice, but the filling also contains chopped large chestnuts, so nearly every cut reveals more of the autumn ingredient. The balance of chestnut sweetness and deep red-bean flavor is designed to be enjoyed with hot green tea.
Okashi no Taiyo has continued making this steamed yokan as an autumn seasonal wagashi. The shop traditionally sold it only during the autumn equinox period, but favorable demand led to this unusual additional production. For customers who missed the earlier release, the October 8 return offers another chance to try the chestnut-heavy sweet before the limited supply is gone.
