Oshi-Katsu Meets Bookstores and Stationery: Shelves, Fairs and Bonus-Card Chaos in Japan

Some bookstores and stationery makers now stock products made for oshi-katsu, such as binders for trading cards and protective supplies for goods. Alongside books and conventional stationery, they are building sales floors around what fans need to collect and store.

Stocking stationery and general goods also brings in revenue beyond books. At the same time, selling limited-edition bonuses raises the problem of hoarding. Drawing on cases from September 2025 onward, this article looks at product lineups and floor design.

Bookstores Are Becoming Places to Stay

According to the credit-research firm Teikoku Databank’s report on bookstore bankruptcies (in Japanese), published June 3, 2025, there was one bookstore bankruptcy from January to May 2025, sharply down from 11 in the same period a year earlier. Yet 58.3% of companies saw their results worsen, and 34.4% were in the red. The decline in bankruptcies came against a backdrop of efforts to create revenue sources beyond book sales. As a survival strategy, the report points to a shift toward “places to stay,” including bigger stationery and general-goods corners.

Oshi-katsu was one destination for that shift. According to an article on 2026 keywords to watch (in Japanese) by Kyodo Printing’s HintClip, which analyzed PR TIMES data, mentions of “oshi-katsu” in press releases have kept rising: 46 in 2021, 891 in 2024 and 1,337 in 2025. That works out to companies using the word about 29 times as often within four years.

The market side backs this up. The third oshi-katsu fact-finding survey (in Japanese), released on January 30, 2026 by the Oshi-Katsu Research Institute (CDG and Oshicoco), covered 23,125 men and women aged 15 to 69 between January 15 and 22. It estimated that the market had grown from about ¥3.5 trillion (roughly $23 billion) the year before to about ¥4.1 trillion (roughly $27 billion), with about 19.4 million oshi-katsu participants, or 24.0% of the total.

Average annual spending, meanwhile, fell to ¥209,716 from ¥255,035 the year before, and the median was about ¥40,000.

So the number of people is up while spending per person is down, a shape that favors bookstores and stationery. Within a median of ¥40,000, a ¥1,760 planner or a binder costing a few hundred yen fits comfortably.

Bookstore Floor Design, Through Cases

CCC’s “IP Bookstore”: Copying a Flagship Format Nationwide

On April 25, 2024, CCC, the company behind the TSUTAYA chain, opened an “IP Bookstore” on the sixth floor of SHIBUYA TSUTAYA, gathering comics, figures and goods in one place. It has three areas: monthly-changing pop-ups, “IP100,” which introduces 100 2D franchises, and “Gallery,” which allows large displays. In December that year the concept expanded to TSUTAYA EBISUBASHI in Osaka. Then on April 10, 2025, CCC announced the rollout of the “IP Bookstore Satellite Store” (in Japanese), which places the same content as a shop-in-shop inside group stores nationwide. The first one opened on April 24 at Fukuoka Tenjin Tsutaya Books.

• Aim: Bring curation once possible only at a large flagship to regional stores
• Approach: Rather than developing a floor from scratch, transplant an established format
• The Oshi Lab’s view: The key was pointing the Shibuya success toward “small copies” rather than “an even bigger flagship.” The hard parts of an oshi-katsu floor are not drawing customers but negotiating with publishers and managing stock. Headquarters takes those on and the stores just provide the space, a structure other industries could borrow

Miraiya Shoten’s “Character Spot”: Permanent Shelves in 17 Stores

On June 17, 2026, the bookstore chain Miraiya Shoten announced that it had opened permanent shelves for anime, comic and game goods, “Character Spot” (in Japanese), in 17 stores nationwide. They carry acrylic stands and pin badges, and the featured titles rotate irregularly, three at a time. The first three were the mobile game Pokémon Masters EX, the manga and anime My Hero Academia and Taishiro-kun, Kimi tte Yatsu wa.

• Aim: Build oshi-katsu goods into the floor as a permanent source of revenue rather than a limited-time one
• Approach: Keep the shelf fixed and rotate only the IP inside, with no run of dates
• The Oshi Lab’s view: The value of a permanent shelf lies less in sales than in the reason to visit: it’s there whenever you go. When a pop-up’s run ends, so does the reason, but the shelf stays. Rotation does mean constantly tracking the renewal cycles of publisher contracts, though, and that doesn’t run without a headquarters function

Kinokuniya Shinjuku Main Store: Keep Hitting Every Month

The Shinjuku Main Store of the bookstore chain Kinokuniya keeps running monthly-changing pop-up stores for anime and manga franchises. From July 30 to August 11, 2025 it was Akuyaku Reijo no Nakano Hito, from August 13 to 24 Kyukyoku Choujin R, and from February 3 to March 4, 2026 Kirarin Revolution in Tokyo and Osaka. The event list (in Japanese) has no gaps.

The aim is for one bookstore to become known as a place that always has some franchise’s pop-up running. In the lab’s view, the payoff of this format depends not on any single run but on whether a habit forms: “if I go, there’ll be something.” Judge it by the return on each run and it won’t last.

Stationery Makers’ Product Design, Through Cases

MARK’S “funlog”: Making Record-Keeping the Brand

On July 15, 2025, the stationery maker MARK’S announced a new brand for enjoying life logging, “funlog” (in Japanese), and released its 2026 life-log planner on August 7. The lineup includes an undated log diary, a weekly block planner, mesh pouches, pen cases and stickers, and it names oshi-katsu, trips to see your oshi and goods management as uses for record-keeping. On June 24, 2026, the brand won an Excellence Award in the Trend category of the 35th Japan Stationery Awards 2026.

• Aim: As an existing planner and general-goods maker, create a dedicated brand for enjoying record-keeping itself
• Approach: Don’t team up with a specific IP; fit the product category to how oshi-katsu actually works
• Award: An Excellence Award in the Japan Stationery Awards’ Trend category (the Grand Prize went to a different product)
• The Oshi Lab’s view: For a company without an IP, fitting products to the behavior is a realistic way into the oshi-katsu market. It needs no license fees or supervision, and it can sell to fans of any genre. In exchange, you have to keep explaining through function why this product exists

Impress’s “Oshi-Katsu Life Planner 2026”: Turning Annual Updates Into a Series

On September 4, 2025, the publisher Impress released the Oshi-Katsu Life Planner 2026 (in Japanese), a B6-size planner priced at ¥1,760 including tax. It has space for reports on 24 live events, records of 88 impressions, goods and ticket management, a monthly layout that lets you write separately for several oshi, and a dedicated “Trip” page for ensei, traveling to see your oshi. As a bonus, buyers also got PDF covers in 10 colors matched to oshi colors.

• Aim: Specialize the planner, a staple bookstore category, for oshi-katsu demand and create yearly repurchase demand
• Approach: Design concrete writing spaces, such as the number of shows and impressions, and support multiple oshi
• The Oshi Lab’s view: A planner is one of the few products where renewal is a given, since it has to be replaced when the year changes. Most oshi-katsu goods end with a single purchase, but repeat buying is built into this one. Handing out the cover in 10 colors as a PDF is also a way to match oshi colors without printing costs

KOKUYO and KING JIM: Balancing “Show” and “Protect”

In an article on the frontline of “oshi-katsu stationery” (in Japanese), published on GoodsPress Web on March 6, 2026, a representative of the stationery maker KING JIM says that usability and ease of customization are prized in stationery for hobbies and oshi-katsu, while a representative of KOKUYO says that oshi-katsu stationery is expected to be both displayable and protective. The trend follows the “favluv” collection binder that KING JIM released in May 2023 and the “Peeplite” pen case that KOKUYO released that June.

What makes oshi-katsu stationery sell is not a printed character. It is that a trading card goes in without bending its corners, that a hard case doesn’t sun-fade, and that pin badges don’t shift inside an ita-bag. Practicality comes first; decoration comes after. We also cover display ideas in storage ideas for oshi goods.

Protect

Keep it safe

• Trading cards go in without bent corners
• Hard cases don't sun-fade
• Pin badges don't shift in an ita-bag

Show

Let it be seen

• Customization and adaptability
• Displays fans can rearrange

Record

Keep the memory

• Planners for shows, trips and goods
• Space for several oshi

A character print alone does not make a product an oshi-katsu product.

When Bonus-Card Hoarding Breaks the Sales Floor

The heaviest problem for bookstore oshi-katsu floors right now is how limited bonuses get handed out.

In “Natsu Comi 2026,” a comics fair that the publisher Shueisha began on July 1, 2026, 22 kinds of newly drawn metallic-foil cards were given out, covering titles such as ONE PIECE, SAKAMOTO DAYS and Kingdom. According to Sirabee’s July 6 report on conditions in stores (in Japanese), stores fell into disorder, with volumes of comics reportedly seen dropping off the shelves right after opening, and Imai Shoten’s Ota store canceled the bonus giveaway altogether. Eyewitnesses reported about 15 people lined up at the register while only two staff members struggled to cope. That same July, hoarding hit the ONE PIECE card bonus in the July 13, 2026 issue of Weekly Shonen Jump, leaving readers who wanted to see the finale of a series that ended in that issue unable to get a copy.

The point to hold onto is that this is not the fault of a particular bookstore or publisher but a result of how the promotion was designed. The moment a limited-quantity bonus is judged more valuable than the main product, buying becomes a competition. It is the problem long seen with random goods and bonuses (tokuten), replayed at the bookstore counter. Bookstores have few register staff, movable shelves that collapse easily, and items that are hard to identify at a glance, so the same design does heavier damage there.

1. 01Limited bonusJudged more valuable than the book
2. 02Buying turns competitiveBulk purchases begin
3. 03Floor strainFew registers, shelves fall
4. 04Distribution canceledOr stock runs out
5. 05Readers leave empty-handedTrust in the store suffers

A design problem, not the fault of one store or publisher.

Patterns That Work and Patterns to Watch For

In every stumbling case the cause is a hole in operations, not the appeal of the product. Bonus distribution is the clearest example: the planning department sets the conditions and the store absorbs them, so where decisions are made and where the burden lands are out of step. Even posting signs that let staff and shoppers identify qualifying books reduces friction at the register.

For Corporate Teams: Steps for Designing Floors and Products

1. Decide first whether it’s permanent or limited-time: Permanent shelves create a reason to visit but require constant management of publisher contracts; pop-ups draw crowds but create workload with every run. If you do both, divide the roles between headquarters and stores first
2. Write oshi-katsu stationery from the functional specs: Card size, pin-badge thickness, fading, losing shape. Settle the real dimensions of what you’re protecting before you start on design
3. Have one product that gets replaced: Planners, refills, sleeves that wear out. One-off goods alone leave nothing to build on next year
4. Check the bonus conditions from the store’s point of view: Write into the plan whether staff can identify a qualifying item in three seconds and how many people one register can handle
5. Announce per-person limits from day one, and allocate stock by store size: Adding limits later leaves the complaint that “you should have done this from the start,” and concentrating stock in big urban stores leaves regional customers empty-handed

Pre-Planning Checklist

• Decided permanent or limited-time, and named who runs each
• Put the per-person cap on purchases and receipts in the announcement
• Decided extra register staffing for day one and the recovery steps when shelves are disturbed
• Have a way to measure store visits and in-store burden, not just sales

Notes From The Oshi Lab: What Bookstores Sell Is a Way to Keep Your Oshi

Explaining the growth of oshi-katsu stationery as a kind of character merchandise isn’t accurate. Neither MARK’S funlog nor Impress’s Oshi-Katsu Life Planner carries a specific IP. They sell because they are tools for preserving oshi-katsu memories. The live show ends, the run of dates is over, goods multiply and run out of places to live. What remains is a page with space for 24 shows and a binder that won’t fade.

We think bookstores are strong in this area because they were always places that dealt in recorded words. Neither the IP bookstore nor the permanent shelf simply puts goods next to books. They gather information and tools about your oshi in one place. Someone who buys a comic picks up a binder and a planner on the way out. How natural that path feels is the bookstore’s asset.

But that asset can be damaged in a single day, as the bonus-card incident showed. Books fall from shelves, and readers who came for the book they wanted go home empty-handed. What is lost is not that day’s sales but trust in the bookstore. What the lab is watching is not which IP comes next, but whether the day comes when in-store operations are written into the blueprint for the bonus.
