Virtual Singer × Traditional Craft: Hatsune Miku x Koshuinden Collab Lands January

There's something oddly perfect about pairing the world's most famous virtual idol with a leather craft that's been around for centuries.

Hatsune Miku is teaming up with Koshuinden (甲州印伝), the traditional stamped-leather craft from Yamanashi, for a new line of leather goods dropping in January 2027 from Kato Shogi (加藤商会).

Two Designs, Four Everyday Pieces

Each item comes in one of two original patterns that capture both sides of Miku's appeal:

• Future (未来) — Miku's signature pop-futuristic vibe
• Tradition (伝統) — classic Koshuinden motifs that only get richer with age

The line-up leans practical: a key case, pen case, card case, and multi case, all crafted in deer-skin leather that'll develop its own patina the more you use it.

The Fans' Favorites Come Back Too

Alongside the brand-new pieces, the collab re-releases two fan-favorites that sold out fast the first time around: the long wallet and the business-card holder.

The Details

• Prices: key cases ¥5,500, pen cases ¥6,599, card cases ¥9,999 (all tax-included)
• Main visual by popular illustrator omutsu (おむたつ) — a cool, Japanese-dress-clad Miku
• Pre-orders are live on Anime Store.JP until September 16

It's the kind of collab built to be carried every day rather than displayed on a shelf — and a Miku × traditional-craft mashup is exactly the kind of mashup I'd reach for my wallet over.
