In an Instagram post from Okayoshi Shoten dated March 14, 2026, the shop announced a thanksgiving celebration to mark the third anniversary of its renewal, along with preparations for a limited-edition can beer by DD4D Brewing. The post says the anniversary event will run for five days: Sunday, March 15; Wednesday, March 18; Thursday, March 19; Friday, March 20; and Saturday, March 21. During the period, visitors will be welcomed with "special-value menu items."

This beer is the "Okayoshi Limited Can," created to celebrate the third anniversary. The can design uses an original illustration by junsato_official, who is also known for wall displays at Okayoshi Shoten, making it something to enjoy visually as well as in flavor. The post also expresses thanks to seri_run_beer as the person who helped bridge the collaboration, showing that this is a beer born from local community connections.

DD4D Brewing is a craft brewery based in Ehime. On its official website, it describes a concept of "enjoying dedication and sharing culture," combining its background in select-shop operations with craft beer brewing. It has many collaboration projects with retailers and food and beverage businesses outside the prefecture, and this limited can also appears to be an extension of DD4D's cross-border approach.

With the spring scenery along the Kandagawa River in view, opening a commemorative can sounds like the perfect way to celebrate. This is a collaboration beer fans will want to check out, offering both the excitement of an anniversary event and the individuality of craft beer at the same time.
