If you’re traveling to Japan in 2026 with any intention of supporting your favorite K-pop idols, anime characters, or J-pop groups, you need to know about oshikatsu (the act of supporting your "oshi" or favorite). Foreign travelers often make the rookie mistake of buying all their protective sleeves, display cases, and concert fan kits at premium specialty stores like Animate or Tower Records. That is a massive waste of your travel budget.
In Japan, the absolute best, most innovative oshikatsu supplies are found at 100 yen shops—specifically Daiso and Seria. For just ¥110 (~$0.75 USD), you can find custom acrylic stand (akusuta) pouches, holograph toploader deco stickers, and concert-regulation uchiwa (fan) kits. But not every 100 yen shop carries these, and the inventory varies wildly between the utilitarian Daiso and the hyper-aesthetic Seria.
This guide strips away the generic tourist advice to give you exact store locations, 2026 prices, and the hard truth about which 100 yen shop products actually protect your expensive merchandise, and which ones will ruin it.

Daiso vs. Seria: The 2026 Oshikatsu Landscape
If you walk into a random convenience store or small local 100 yen shop, you won't find these goods. You need to target specific brands and store sizes.
Seria is the undisputed king of otaku aesthetics. They were the first to realize that fans want cute, color-coordinated items. Their "Ota-Katsu" line features pastel, gothic, and retro themes tailored for customized photocard decoration. Daiso, on the other hand, excels at heavy-duty storage, large binders, and bulk displays. While Seria focuses on making your one favorite photocard look amazing, Daiso focuses on how to cleanly store your collection of 500 cards.
Brand Comparison at a Glance
| Feature/Item | Daiso (ダイソー) | Seria (セリア) |
|---|---|---|
| Best For | Large binders, display racks, clear ita-bags | Toploader deco, plushie clothes, acrylic cases |
| Aesthetic | Minimalist, clear, functional, basic colors | Frilly, lace, gothic, pastel, highly stylized |
| Photocard Sleeves | Bulk packs (100 sleeves for ¥110 / ~$0.75 USD) | Hard PVC toploaders with foil stamps |
| Standard Price | ¥110 to ¥550 (~$0.75 - ~$3.70 USD) | Strictly ¥110 (~$0.75 USD) |
| Plushie Goods | Clear carrying pouches (¥330 / ~$2.25 USD) | Mini capes, hats, and sunglasses for nui (plushies) |
Acrylic Stand (Akusuta) Cases & Storage
Acrylic stands (akusuta) are the undisputed most popular merchandise in Japan right now. Carrying them around to take photos at cafes is a core oshikatsu activity.
Seria's Akusuta Pouches
Seria dominates the portable case market. Their ¥110 (~$0.75 USD) EVA zipper pouches come with pre-cut binder rings and soft insert sheets. In 2026, their newest releases include "quilted" fake leather cases in 9 different "member colors" (red, blue, green, etc., to match your idol).
Daiso's Display Cases
If you want to display your stands at your hotel or take them home, head to Daiso. They sell stackable, stepped acrylic risers (¥110 to ¥330 / ~$0.75 to $2.25 USD) that rival the ¥2,000 ($13.50 USD) versions sold at Muji.
Honest Local Tip: Tourists often buy the Daiso "clear ita-bag totes" (the bags with a clear window to show off badges and stands) for ¥550 (~$3.75 USD). Do not buy these. The PVC window is extremely cheap, fogs up quickly, and cracks easily in cold airplane cargo holds or winter weather. If you want a real ita-bag, go to WEGO in Harajuku (around ¥4,500 / ~$30 USD) and just use the 100 yen shops for the inserts that go inside the bag.
Uchiwa Kits & Concert Gear
If you are attending a concert (especially for K-Pop or Starto Entertainment/former Johnny's groups), handmade jumbo uchiwa (fans) are mandatory.
Buying pre-made fan kits at Tower Records will cost you ¥800 to ¥1,500 (~$5.40 - $10.00 USD). Daiso and Seria sell the exact same blank jumbo fans for ¥110 ($0.75 USD). More importantly, 100 yen shop fans are strictly manufactured to be 29.5cm x 28.5cm—which is the maximum legal size allowed by strict Japanese idol agency concert regulations.
- Uchiwa Covers: Seria sells heavy-duty zippered uchiwa covers that protect your fan from rain while queuing for merch.
- Deco Stickers: Both stores sell high-visibility neon and holographic sticker sheets (¥110 / ~$0.75 USD) pre-cut into Japanese phrases like "Point at me!" (指さして) or "Shoot me a peace sign!" (ピースして).
Top 100 Yen Shops for Otaku in Tokyo
Do not waste your time at tiny neighborhood branches. You must go to "Mega" (大型店) locations.
1. Daiso Ikebukuro Tobu Store (6th Floor)
- Location: Connected directly to Ikebukuro Station West Exit, inside the Tobu Department Store, Floor 6.
- Why it's elite: Ikebukuro is the female-oriented otaku capital of Tokyo. This Daiso spans a massive floor plan and dedicates two entire aisles exclusively to oshikatsu. It has the best stock of trading card binders in the city.
- Search best hotels in Japan on Booking.com (Staying in Ikebukuro is highly recommended for otaku travelers).
2. Seria Shinjuku Marui Annex (3rd Floor)
- Location: Shinjuku San-chome Station, Exit C4. 3-minute walk to Marui Annex.
- Why it's elite: The Marui Annex is a known otaku hub (Surugaya is on a higher floor). This Seria is intentionally stocked for collectors. If a new cute B8 toploader goes viral on Japanese X (Twitter), this store will have a dedicated endcap for it within days.
3. Daiso Global Flagship Ginza (Marronnier Gate 6F)
- Location: 3-minute walk from Yurakucho Station Central Exit.
- Why it's elite: While Ginza isn't an otaku hub, this flagship store is so massive that it carries the entire Daiso catalog, making it a reliable backup if Ikebukuro is sold out of a specific item.

Deco Stickers & B8 Toploaders

Customizing photocards is a religion in the 2026 oshikatsu scene. The standard photocard (K-pop album cards or Cheki polaroids) fits in a B8 size sleeve (64 x 91 mm).
The Tourist Mistake: Buying cheap, soft "OPP sleeves" from Daiso and thinking they provide enough protection for international travel. They don't. Your cards will bend in your luggage.
The Solution: You must buy Hard Toploaders (硬質ケース). Seria is famous for selling B8 hard toploaders that come pre-decorated with holographic foil stamping—featuring lace, butterfly, or gothic frame designs. You get a pack of 2 to 4 hard decorated loaders for ¥110 ($0.75 USD). At an anime shop, a single decorated hard case costs ¥400+ ($2.70+ USD).
Price Reality Check: 100 Yen Shop vs. Specialty Store
| Oshikatsu Item | 100 Yen Shop (Daiso/Seria) | Premium Specialty Store | Savings |

Frequently Asked Questions
Q: How much do oshikatsu supplies cost at 100 yen shops in 2026?
The vast majority of oshikatsu supplies at Seria are strictly ¥110 (which includes the 10% consumption tax), making them roughly equivalent to $0.75 USD depending on the current 2026 exchange rate. Daiso operates slightly differently; while their basic sleeves, uchiwa fans, and stickers are ¥110, they also offer premium tiered items. For example, Daiso's large multi-ring display binders or their plushie carrying bags will usually run you ¥220 ($1.50 USD) or ¥330 ($2.25 USD). Even at the ¥330 tier, you are saving enormous amounts of money compared to specialty otaku stores where similar binders easily cost over $15 USD.
Q: Does Daiso or Seria have better photocard holders?
Without a doubt, Seria has the better photocard holders if you care about aesthetics and customization. Seria's dedicated "MyFave" line focuses heavily on B8-sized hard toploaders that are embellished with holographic foil, lace patterns, and framing designs that perfectly highlight a K-pop photocard or instax cheki. They also stock keychain photocard holders in various pastel shapes. Daiso, conversely, is the better option if you just need sheer volume. If you have 400 Pokemon cards or idol trading cards to store, Daiso's massive packs of 100 utilitarian clear sleeves and high-capacity binder pages are vastly superior.
Q: Are these supplies suitable for K-Pop photocards or only Japanese anime goods?
They are absolutely perfect for K-Pop photocards. Due to the massive, sustained popularity of K-pop groups like Seventeen, Stray Kids, and NewJeans in Japan, the Japanese 100 yen shops have entirely adapted their sizing to fit the K-pop market. Standard K-pop photocards are roughly 55x85mm. When browsing Seria or Daiso, simply look for the prominently displayed "B8" sizing on the packaging, which perfectly fits these cards with just enough room for a penny sleeve. Standard Japanese anime trading cards (like Pokemon or Weiss Schwarz) are slightly larger (63x88mm), so ensure you check the label before buying.
Q: What is the biggest 100 yen shop in Tokyo for idol merchandise?
For idol merchandise specifically, the absolute best location is the Daiso located on the 6th floor of the Tobu Department Store in Ikebukuro (connected to the Ikebukuro Station West Exit). Because Ikebukuro is Tokyo's primary hub for female otaku and idol fans, this specific Daiso allocates massive floor space to oshikatsu supplies, trading card accessories, and ita-bag components. Another phenomenal option is the Seria located on the 3rd floor of the Shinjuku Marui Annex. Since the Marui Annex hosts numerous anime pop-up shops, this Seria caters directly to the collectors shopping in the very same building.
Q: Why can't I find oshikatsu goods at small neighborhood 100 yen shops?
Small neighborhood branches of Daiso and Seria operate on very limited square footage. Their inventory management algorithms prioritize daily survival necessities for local residents—think laundry detergent, basic kitchen sponges, and cheap groceries. They simply do not have the shelf space to dedicate an aisle to holographic sticker sheets and concert fans. To find the goods mentioned in this guide, you must seek out stores classified as "Large-scale stores" (大型店 - Chogata-ten) on the official Japanese store locator websites. Shopping in major commercial wards like Shinjuku, Shibuya, or Ikebukuro guarantees you are hitting these larger footprint stores.
Bottom Line
If you are an idol fan or anime collector traveling to Japan in 2026, skipping the 100 yen shop oshikatsu aisles is leaving money on the table. Seria is your undisputed destination for cute, aesthetic photocard toploaders and acrylic stand pouches, while Daiso remains king for bulk storage and heavy-duty binders. Both stores offer unmatched value for concert uchiwa kits, keeping you strictly within Japanese venue regulations for just ¥110 (~$0.75 USD). However, this guide is not for collectors looking for premium, genuine leather display cases, UV-resistant museum-grade acrylics, or high-end apparel bags—for those, you will still need to visit specialty otaku boutiques or department stores. But for everyday cafe hopping and photocard trading, Daiso and Seria are the only supply stops you need.
