Every so often a piece of anime merchandise crosses my desk that instantly transports me back to a specific moment in the source material — and this USJ Limited Edition wrist anesthesia gun watch from Detective Conan is exactly that kind of object. For fans who grew up watching Conan Edogawa fire tranquilizer darts at unsuspecting criminals before pushing Kogoro Mouri into deductive glory, this wearable prop replica is more than a novelty; it is a piece of narrative apparatus. Released as part of Universal Studios Japan’s Detective Conan collaboration in 2023, it sits in that increasingly narrow category of theme-park-exclusive collectibles that never see a wide retail release.
Japanese Goods & Accessories occupy a distinct tier in the collectibles world. Compared to international licensed merchandise, Japan-market items tend to prioritize screen-accurate detailing, higher-grade plastics, and packaging that treats the product as archival. USJ event exclusives in particular are famously short-run — often produced in tightly controlled quantities to match park attendance projections — which means they disappear from shelves within weeks and rarely resurface outside the domestic secondary market.
About This Item
This is the Detective Conan Wrist Anesthesia Gun Watch, produced as an official Universal Studios Japan limited edition tied to the 2023 “Detective Conan The World” event run. Modeled directly on the wrist-mounted tranquilizer gadget invented by Professor Agasa and used by Conan throughout the manga and anime, the watch faithfully replicates the analog dial face, the button-triggered firing mechanism silhouette, and the compact strap design seen in the series. The 2023 USJ collaboration was one of the most anticipated tie-ins of the year, coinciding with the release of the theatrical film “Black Iron Submarine,” and merchandise was manufactured specifically for park distribution by USJ’s licensed partners under supervision from Shogakukan and TMS Entertainment.
What sets this piece apart from generic Conan watches sold at regular retail is the USJ event branding, the exclusive packaging design, and the fact that it was only sold within the Osaka park during the collaboration period. We have handled several pieces from this event line, and the finish quality on the wrist unit is notably heavier and more detailed than mass-market equivalents from prior years. This unit is offered in pre-owned condition, carefully inspected, and shipped from Japan.

The Detective Franchise: Why Collectors Care
Detective Conan, created by Gosho Aoyama and first serialized in Weekly Shonen Sunday in 1994, has grown into one of the longest-running and highest-grossing manga franchises in Japanese publishing history. According to Shogakukan’s official series page (https://websunday.net/), the manga has surpassed over 100 tankobon volumes with cumulative sales exceeding 270 million copies worldwide. The anime adaptation, produced by TMS Entertainment since 1996, remains a weekly fixture on Japanese television, and the annual theatrical films have consistently broken domestic box office records — with the 2023 entry “Black Iron Submarine” earning over 13 billion yen as reported by Toho’s official box office disclosures.
The wrist anesthesia gun is arguably the most iconic gadget in the entire series, appearing in the very first chapter as the plot device that allows the shrunken Shinichi Kudo (now Conan) to solve cases without exposing his true identity. Its cultural weight inside the fandom is difficult to overstate.
Rarity and Value Factors
USJ event merchandise operates under a scarcity model that differs sharply from standard retail. Items are typically produced in a single manufacturing run sized to expected event attendance, and once the collaboration period ends — usually three to five months — no restocks are issued. According to collector forums tracking the 2023 Detective Conan event, several signature items sold out within the first month of the run. Condition scarcity compounds this: because the watch was designed to be worn around the park, many surviving units show strap wear or scuffed dial faces. Sealed, unworn examples with the original USJ tag intact command significant premiums on the Japanese secondary market, particularly among completionist collectors targeting the full 2023 event lineup.

Collector’s Guide: What to Look For
When evaluating a pre-owned USJ Detective Conan wrist watch, the inspection process matters more than with mass-produced merchandise because there are no reissues to fall back on. In my experience handling event-exclusive wearables, the strap and the dial face are the two components most likely to show honest wear. We inspected this piece for hairline cracks near the strap pin, for adhesive lift on the dial decal, and for oxidation on any metallic trim — all of which are common failure points on watches that were worn during park visits rather than kept sealed. The firing mechanism is decorative rather than functional, but the button should still depress cleanly without sticking.
Original packaging and the USJ-exclusive hangtag dramatically affect long-term value. Because the event branding on the packaging is what distinguishes this from generic Conan watches, a loose piece without box or tag loses a substantial portion of its collector premium.

Condition Checklist
- Strap Integrity: Check for cracks, stretched holes, or discoloration on the band, especially near the buckle
- Dial Face: Inspect for scratches, decal lift, or fading of the printed Conan-themed graphics
- Firing Mechanism Button: Confirm the button depresses and returns cleanly without sticking
- Movement (if applicable): Verify the watch keeps time and the second hand sweeps without hesitation
- Packaging: Original USJ box, exclusive hangtag, and any insert cards are critical to value retention
Price Guide
Based on tracked auction data across major Japanese secondary markets during 2024, pre-owned examples of this specific USJ 2023 wrist watch typically fall into the following bands. Loose, worn condition without box: roughly $60–$95. Good condition with box and moderate wear: $110–$160. Mint or near-mint with all packaging, hangtag, and inserts: $180–$260, with sealed examples occasionally exceeding that ceiling at specialist auctions. The single largest price driver is packaging completeness — a mint watch without the USJ box loses roughly 40% of its collector value, since the event provenance is what separates this from generic Conan merchandise.
Similar Items Worth Exploring
Collectors drawn to this piece typically also pursue other Detective Conan gadget replicas and USJ 2023 event exclusives. The bow tie voice changer replica — another Agasa invention — is a natural companion piece, as is the turbo-engine skateboard prop from earlier merchandise waves. From the same 2023 USJ event, the Kaito Kid card gun keychain and the APTX 4869 pill capsule pin badges round out a coherent thematic collection. For those focused on wearable items specifically, Bandai’s Character Watch line has released several standard-retail Conan timepieces over the years, though none carry the event-exclusive premium of the USJ variant. Movie-tie-in figures from the “Black Iron Submarine” release period also share the same production window and complement this watch nicely in a display case.
Why Buy Japanese Collectibles from Japan?
Japanese collector culture places exceptional emphasis on preservation. Boxes are kept, tags remain attached, and items are frequently stored in climate-controlled conditions from the moment of purchase. Theme park exclusives like USJ event merchandise are, by definition, unavailable through international retail channels — the only reliable sourcing path is the Japanese secondary market. Buying from Japan-based specialists also means the item’s provenance can be verified against known event production runs, reducing exposure to unlicensed reproductions that occasionally surface overseas. Contact our team if you have questions about authenticity, and refer to our returns policy for inspection guarantees on pre-owned event merchandise.
Summary
The USJ 2023 Detective Conan Wrist Anesthesia Gun Watch is one of those rare collectibles that combines narrative significance, wearable design, and event-exclusive scarcity into a single object. For long-time Conan fans, it represents the most iconic gadget from a franchise now approaching its fourth decade. For collectors of Japanese theme park exclusives, it is a discrete, well-documented artifact from a specific 2023 event window that will not be reproduced. Last reviewed: March 2024.
