What this is
The Ace of Diamond Act II -Second Season- POP UP SHOP 2026 is a limited-run official merchandise event celebrating the popular baseball manga and TV anime series Ace of Diamond. Running from July 3 to July 12, 2026 at Shinjuku Marui Men's 8th floor event space, the shop features newly commissioned illustrations themed around 'watching a baseball game' and 'shopping.' Fans can purchase exclusive goods featuring these fresh illustrations in advance of wider release. The event also includes standee panel displays and a purchase lottery held on-site, making it a destination for collectors and dedicated fans of the series.
Who should go
This event is ideal for fans of the Ace of Diamond anime and manga series, as well as collectors of anime merchandise and limited-edition goods. The atmosphere will be enthusiastic and community-driven, drawing dedicated fans eager to snap up exclusive items before they sell out. Casual anime fans and those curious about Japanese pop-up culture will also find the event visually engaging thanks to the standee displays. Arrive early in the day, especially on weekends, as popular items and lottery slots tend to go quickly at events like this.
Good to know
Entry to the event space is free, but popular limited-edition goods can sell out quickly — especially on opening day and weekends. Shinjuku Marui Men is a well-known fashion and lifestyle department store in Shinjuku, and the 8F event space is a compact but dedicated pop-up venue regularly used for anime and character goods events. Payment methods at pop-up shops within Marui stores typically include major credit cards and IC cards, but it's wise to carry some cash as a backup. The on-site purchase lottery means buying certain items requires entering a draw rather than purchasing directly — lottery details and eligibility rules will be posted at the venue. Foreign visitors should note that some lottery prizes or limited goods may require a Japanese address for shipping if not collected on the day.
