A colorful train featuring characters from the new anime Kaiju Sekai Seifuku and idol group Rosy Chronicle is now running on Tokyo’s JR Chuo Line. Here’s how you can spot it—and maybe catch a ride!
Ride the Kaiju Train! Anime × Idol Collaboration Hits the Tracks
What happens when a cozy monster-themed anime meets a rising idol group? You get a vibrant wrapping train gliding through Tokyo! The anime Kaiju Sekai Seifuku and idol group Rosy Chronicle have teamed up for a limited-time train ad campaign on the JR Chuo Line—and it’s absolutely adorable.
Where and When to Catch the Wrapping Train
The train runs on the JR Chuo Line Rapid Service, a route connecting Tokyo Station with western areas like Tachikawa and Hachioji. It began service on April 6 (Sunday) and will operate until May 3 (Saturday), 2025. That gives fans a full month to try their luck spotting it!
How to Spot the Only Wrapped Train on the Chuo Line
Here’s the catch: only one train is wrapped. There’s no official timetable or schedule for when it appears, so it’s all about timing and luck. Your best bet? Try early weekend mornings when train frequency is high and anime-themed rides are often scheduled for visibility. Please don’t ask station staff—they won’t be able to help!
More About the Anime and Rosy Chronicle
The anime Kaiju Sekai Seifuku just started airing on April 5, and it’s based on a warm, comedic four-panel manga about kaiju living alongside humans. The theme song is performed by Rosy Chronicle, a brand-new group from Hello! Project, making this both a debut and a crossover to remember.
Summary & Call to Action
Whether you’re a fan of cuddly kaiju or up-and-coming idols, this wrapping train is a fun and fleeting piece of pop culture on wheels. Running through Tokyo’s JR Chuo Line until early May, it’s a rare chance to experience anime in motion—literally!
