Osamu Miya, Haikyuu’s Culinary Twin, and the Jirori Line

Osamu Miya Haikyuu Jirori Trading Acrylic Keychain

A Trading Keychain from Japan’s Anime Goods Scene

This is a trading acrylic keychain — known in Japan by the shorthand torekie — from the official Haikyuu!! merchandise range. The format is simple: a small acrylic disc printed with a character illustration and fitted with a silver split ring. What makes the “trading” designation significant is the packaging: these keychains are sold blind, meaning the buyer cannot see which character is inside until the package is opened. The full series spans multiple characters, and any given purchase is random. That structure — deliberate uncertainty built into the product — is a cornerstone of how Japanese anime collectibles work. Fans who want a specific character either keep buying until they land it or find it through trading and secondary channels. Obtaining a single character like Osamu Miya requires either luck or targeted effort.

Osamu Miya: The Cooking Twin Behind the Glasses

Haikyuu!! is a high school volleyball manga by Haruichi Furudate, serialized in Weekly Shonen Jump from 2012 to 2020 across 45 collected volumes. The TV anime, produced by Production I.G, ran for four seasons beginning in 2014. A two-part theatrical conclusion produced by MAPPA followed in 2024, bringing the series to a full close. The manga and anime have developed a broad international following, with global streaming through platforms such as Crunchyroll and Netflix.

Osamu Miya is a middle blocker for the Inarizaki High volleyball team, wearing number 11. He appears inseparably alongside his twin brother Atsumu — a setter, number 1 — and the two together form one of the series’ most distinctive character pairings. Osamu is typically portrayed as the cooler, more measured twin; he wears glasses and, notably, has a deep interest in food and cooking. The manga suggests that he eventually pursues a culinary career after his high school years. That combination of sibling contrast, quiet personality, and an unexpected backstory detail has earned him genuine popularity on his own terms, not just as half of the Miya duo. Inarizaki High’s major story arc falls in the portion of the anime adapted in Season 4 (2020), and Osamu’s merchandise presence expanded meaningfully from that period onward.

Jirori’s Chibi Style and What It Means for Collectors

The “Jirori” name identifies a specific art direction within the official Haikyuu!! goods lineup. Rather than drawing on the manga’s standard character designs, the Jirori series uses a super-deformed, chibi-style illustration — a compact, round-headed visual approach common in Japanese anime merchandise. This gives pieces in the Jirori line a distinctly different look from other licensed Haikyuu!! products, and collectors who follow a single character across different merchandise lines will treat the Jirori style as its own category worth acquiring separately.

The copyright notice on the item — © HF/S,HP,M — points to Furudate (HF), Shueisha (S), the Haikyuu!! production committee (HP), and MBS broadcaster (M), confirming it as a formally licensed product connected to the anime’s broadcast run. The precise manufacturer is not identifiable from the packaging information alone; multiple licensed producers have released official Haikyuu!! goods over the years. What the copyright does confirm is that this is an authorized piece, not a reproduction. For international fans who follow the series through streaming and want to connect with the Japanese merchandise side of the fandom, that official licensing is a meaningful distinction.
