On Ise Kadoya Beer’s official Instagram (`@isekadoyabrewery_official`), it shared spring IPA set information under "🌸 The Spring IPA Festival is ready! 🌸". The post states that it is a 6-bottle set combining the popular neko series, the latest "Brain-Melting Ultra Heaven 3xIPA," and the much-talked-about "Another Cut."

On the special page for the official online shop, "Spring IPA Festival 2026", the set contents are listed as the following six beers.

- Hop Nyaon 11th Fleet (DDH Hazy IPA)
- Neko Sanbiki (TDH Opaque Triple IPA)
- Neko Nihiki (Hazy Double IPA)
- Neko Shika Shinjirarenai (DDH Opaque DIPA)
- Brain-Melting Ultra Heaven 3xIPA (American Style Triple IPA)
- Another Cut (Hazy IPA)

The page lists the price at 5,500 yen (tax included). Alcohol content ranges from 6.5% to 10.0%, and IBU ranges from 35 to 88, making it a lineup that lets drinkers compare IPA-derived styles such as hazy, double, and triple.

Ise Kadoya Beer is a craft brewery based in Mie that also describes itself on its official website as "top-level by global standards." This spring campaign is a seasonal proposal that lets drinkers experience the breadth of its hop expression in one box, making it approachable not only for existing fans but also for IPA beginners.
