What this is
This is an official pop-up store for the TV anime 'Mob Psycho 100 III,' held at the iconic Kinokuniya Bookstore in Shinjuku from June 18 to July 1, 2026. The event celebrates the series with a 'Rainy Season' theme, featuring newly illustrated mini-character artwork of beloved characters including Kageyama Shigeo (Mob), Reigen Arataka, Kageyama Ritsu, Hanazawa Teruki, and Ekubo. Alongside the seasonal collection, new merchandise marking the 10th anniversary of the Mob Psycho 100 franchise will also be released. The merchandise lineup includes puddle acrylic stands, aurora acrylic keychains, trading umbrella markers, and A4 clear file sets — all exclusive to this limited-time event.
Who should go
This event is ideal for fans of Mob Psycho 100 and anime merchandise collectors who want to pick up limited-edition, theme-specific goods unavailable elsewhere. The rainy season aesthetic and 10th anniversary items make it especially appealing to long-time followers of the series. Casual anime fans browsing Shinjuku will also find it a fun stop given its central, accessible location inside a major bookstore. Arrive early in the event run — popular trading items and random giveaways tend to sell out quickly at pop-ups like this.
Good to know
Entry to the pop-up area is free, but merchandise purchases are the main draw — budget accordingly if you plan to collect multiple items or chase all 8 Weather Fortune Card designs. Kinokuniya Shinjuku Main Store generally accepts major credit cards including foreign-issued Visa and Mastercard, making it convenient for international visitors. The 1F THE ENTRANCE area is a high-traffic zone near the store's main entrance, so expect it to be busy, especially on weekends and during the opening days. Pop-up stores at Kinokuniya Shinjuku typically run during regular store hours (roughly 10:00–21:00), though confirm exact hours via the official event website. Stock of limited trading items can deplete quickly, so weekday morning visits are your best bet for full selection.
