A Mystery Game You Can Only Play on a Moving Shinkansen
The campaign's full title is JR Central "Oshi-Tabi" x Detective Conan: Tokaido o Kakeru Nazotoki Shinkansen (Bullet Train), roughly "a puzzle-solving bullet train racing down the Tokaido." It works like this: riders board a Tokaido Shinkansen train, access the campaign site from their seats, and answer a short survey. That unlocks a round of five randomly drawn mystery puzzles, pulled from a pool of 50 questions that includes campaign exclusives. Every puzzle comes with a hint, and the whole set is supervised by Detective Conan Zemi, the franchise's educational service for elementary school students, so the difficulty is pitched at children and adults alike.
According to the Oricon News report, players can obtain one boarding proof per person per day, no matter how many rounds they clear.
Oshi-Tabi (the name roughly means "a trip for your fave") is JR Central's fan-travel program, which pairs Tokaido Shinkansen trips with anime and game franchises and has previously run tie-ups with titles like Spy x Family.
Keychains Featuring Kaito Kid and Toru Amuro
Riders who answer all five puzzles correctly earn an original-illustration acrylic keychain, redeemable at the Sanseido Bookstore Nagoya main store on the 8th floor of Takashimaya Gate Tower Mall, directly connected to JR Nagoya Station. The designs rotate with the calendar: the first half of the campaign (August 10 to September 18) and the second half (September 19 to November 9) each feature three different designs, handed out at random, one per person per day, while supplies last. Oricon's photo gallery confirms fan favorites Kaito Kid and Toru Amuro are among the illustrations.
Every ride also unlocks all 10 AR photo frame designs featuring the campaign's original artwork. Each frame stays usable until 11:59 p.m. the day after it is claimed, or until the end of the day on the campaign's final date.
A Lottery-Only Railway Tour, With Conan in Attendance
The biggest prize is not merchandise. Twenty-five pairs of winners, drawn by lottery, will be invited to a campaign-original "Railway Work Experience Tour" at the JR Central General Training Center in Mishima, where participants get to study and try out various railway jobs. Conan himself makes an appearance on the day for commemorative photos. Entries are limited to once per day, and full tour details will be posted to the campaign site at a later date.
Looking Ahead
The campaign kicks off August 10 and runs through November 9, 2026, and playing requires actually being aboard a Tokaido Shinkansen. That makes this one squarely aimed at fans in Japan, or anyone visiting along the Tokyo-Nagoya-Osaka corridor this fall who wants a themed excuse to ride the bullet train. For everyone else, Detective Conan is easier to watch internationally than it has ever been: Crunchyroll and Netflix stream curated episode collections with a new English dub, most recently the "FBI Intervention" set added in May 2026. Gosho Aoyama's original manga is published in English by Viz Media under the title Case Closed.
