Nanatsuya Shinobu no Houseki Bako, Tomoko Ninomiya’s ongoing manga in Kodansha’s Kiss magazine, is getting a TV anime. It is set to air in 2027. A teaser visual and teaser trailer went live alongside the announcement, and the official website and official X account are now open.
Tomoko Ninomiya is, of course, the author of Nodame Cantabile. On top of that, Chiaki Kon, who directed the second season Nodame Cantabile: Paris Chapter and the third season Nodame Cantabile: Finale, is directing. Plenty of readers took one look at that pairing and immediately understood exactly what kind of atmosphere this adaptation is aiming for.
The story unfolds in a long-established pawnshop in Tokyo’s old downtown. Jewelry and a pawnshop make for a genuinely unusual pairing as anime subject matter. This article walks through the staff list that was revealed, the shape of the series itself, and even the industry-association comments that came with the announcement.
What kind of story is Nanatsuya Shinobu no Houseki Bako?
It is a story built around jewelry and pawnbroking, set in a long-running pawnshop in Tokyo’s old downtown. The protagonist is Shinobu Kurata, a young woman who can sense the “energy” inside gemstones. The other pillar of the cast is Akisada Kitakami, the son of a distinguished family who works at an established high-end jewelry store.
There is no shortage of manga about gemstones, but one set inside a pawnshop is rare. The shop functions as the story’s engine: a place where value is appraised, items are held in trust, and goods move on. That setting is exactly what lets the series depict not only the beauty of the stones but the circumstances of the people who owned them.
| Item | Details |
|---|---|
| Original manga | Tomoko Ninomiya (serialized in Kodansha’s Kiss) |
| Director | Chiaki Kon |
| Series composition | Seishi Minakami |
| Character design | Mai Furuki |
| Animation production | J.C.STAFF |
| Broadcast | 2027 |
Director Chiaki Kon handled both Nodame Cantabile: Paris Chapter and Nodame Cantabile: Finale. Having someone who already worked on an anime from the same mangaka step straight into the new adaptation matters enormously for pacing and comic timing. Animation production is at J.C.STAFF.
How much was revealed at the announcement?
Four things: the teaser visual, the teaser trailer, the core staff, and the broadcast year. Cast and broadcast network have not been officially announced as of November 2026.
A celebratory illustration from Tomoko Ninomiya herself was also published. It is being turned into a postcard and given away to five people chosen by lottery. Five winners is exactly the kind of tightly limited giveaway you expect from a campaign run out of a manga magazine.
Comments from industry associations make this announcement unusual
The detail that stood out here was the row of comments from the jewelry and pawnbroking industry associations. Three figures weighed in: Hisao Kato, chairman of the National Gemstone Wholesalers Cooperative Association; Masahiro Kadono, president of the National Federation of Pawnbrokers Associations; and Shokun Sai, chairman of the National Pawnshop Brand Goods Association.
Kato noted that the birthstone list was revised in 2022, adding ten stones for a total of 29. Sai pointed out that pawnbroking has more than 700 years of history behind it. When an anime announcement arrives bundled with a primer on the industry, that tells you how specialized the subject matter is. And honestly, I had no idea the birthstone count had climbed to 29 either.
What should you catch up on before the 2027 broadcast?
Two things: the serialized Kiss chapters, and the teaser trailer that is already out. The series airs in 2027, so neither the season nor the network is known yet.
Here is my honest concern. A story about gemstones lives or dies on how the texture of those stones reads on screen. If the stones do not catch the light inside a cut, the core of this series dies with them. How J.C.STAFF and character designer Mai Furuki handle that is what I want to see beyond the teaser.
Flip it around, though, and having Chiaki Kon, who knows the Nodame Cantabile staging inside out, in the director’s chair makes the character-drama side fairly easy to predict. Where the balance lands between showcasing the jewelry and the human drama is worth the wait on its own.

Summary: Nanatsuya Shinobu no Houseki Bako airs in 2027 with Chiaki Kon directing
Nanatsuya Shinobu no Houseki Bako, Tomoko Ninomiya’s series running in Kodansha’s Kiss, will air as a TV anime in 2027. Chiaki Kon directs, Seishi Minakami handles series composition, Mai Furuki is on character design, and J.C.STAFF is producing the animation.
As of the announcement, the teaser visual, teaser trailer, core staff, and broadcast year are public. Cast and network remain unannounced as of November 2026. The author’s celebratory illustration is being given away as a postcard to five lottery winners.
Jewelry and a pawnshop as subject matter, with Chiaki Kon, who directed the Nodame Cantabile anime, taking the director’s chair. That alone earns this a slot on your 2027 watchlist. An announcement carrying comments from three industry associations is a rarity too, and the sheer specialization of the material should turn into one of the series’ real strengths.
No cast yet. Whoever ends up voicing Shinobu Kurata and Akisada Kitakami will push the hype up another notch.
