Our take
18 March 2026 is the day before the one-year mark to opening day, 19 March 2027. The first collaboration appeared in September 2025, in the closing weeks of Expo 2025 Osaka, and sold out; the restock lands on the one-year countdown. Why Myaku-Myaku goods continue after the Osaka Expo closed in October 2025 is explained in where Myaku-Myaku went.
Six new items from 880 to 1,980 yen, split between things to use (a knapsack, pouches) and things to display (a mini banner, a medal). Four restocked items, clear files and stickers, at 520 to 770 yen. Keep the sold-out basics cheap, lift the average with new items.
Stock by store is not listed in the release. The official store inside Maruzen Marunouchi sits by Tokyo Station, where people change between the Shinkansen and local lines, which makes it a place to buy before you ever reach Yokohama.
Tips for visitors
- On sale from 18 March in stages. The official store at Maruzen Marunouchi and the online store start on 20 March.
- The cheapest options are the four restocked items (520 to 770 yen). New items run 880 to 1,980 yen. Stock by store is not published, so check in person.
- More collaborations follow. See our round-up and, for the character after the Expo, where Myaku-Myaku went.

Our take
A restock five months after the Osaka Expo closed, with a clear aim of carrying its popularity over to Yokohama. The four restocked items cost 520 to 770 yen, an easy souvenir before opening day. The Maruzen Marunouchi store is right outside Tokyo Station, handy on a Shinkansen transfer.
