What this is
A limited-edition confectionery collaboration between The Idolmaster SideM character Pierre and Nagoya's historic Aoyagi Sohonke wagashi shop, sold exclusively at their Osu main store from August through September 2026. Part of the ongoing 'Dera Masu' project, it reimagines the shop's signature Frog Manju (Kaeru Manju) with special anime-themed packaging and an original bonus item. The box itself doubles as a photo prop — the back panel folds into a papercraft piece designed for taking pictures alongside the manju.
Who should go
Idolmaster SideM fans visiting Nagoya, particularly those following Pierre or the Dera Masu project. Anime merchandise collectors who enjoy food-based collaborations will find this a neat regional pickup.
Good to know
This is a retail sales collaboration, not a ticketed event — no reservation is needed, just visit the Aoyagi Sohonke Osu Main Store during opening hours within the sales period. Payment is likely cash or card at the shop counter; confirm card acceptance on arrival as smaller traditional wagashi shops sometimes prefer cash. Stock of limited-edition packaging and bonus items may sell out before the September 16 end date, so don't leave it to the last week. The Osu area is a great base for anime and retro goods shopping more broadly, with many related stores nearby.
