This spring, Pompompurin fans are in for a treat as the East Japan Railway Company teams up with the Sanrio Company for a limited-time railway adventure from Tokyo to Yamanashi Prefecture!
Running from 3 April to 30 June 2026, this campaign titled “A Relaxing Train Journey with Pompompurin” (ポムポムプリンと過ごすのんびり列車旅) is one part of Pompompurin’s 30th anniversary celebrations and features a series of fun, interactive experiences along the Chuo Line of JR East.
Take it easy with everyone’s favourite Golden Retriever!
Inspired by Pompompurin’s laid-back personality, this campaign invites travelers to slow down and enjoy the journey. Across multiple areas in Tokyo and Yamanashi, fans will be able to explore stations, trains, and shopping facilities transformed into a Pompompurin-themed world.
Limited Edition Stamp Rally
At the heart of the campaign is a digital stamp rally on the mobile application “EKITAG”, spanning six themed areas along the Chuo Line from Kichijoji Station to Kobuchizawa.
Please refer to the original site for the detailed location list.
Simply drop off any of the listed train stations above and find the stamp station to collect the prerequisite Pompompurin stamp in your application. It’s the perfect excuse to hop on and off trains while discovering hidden gems along the Chuo Line, such as the trendy cafes of Kichijoji, wine in Yamanashi, or the outdoors escape of Oku-Tama.

Simply open the application when one of the designated LTD EXP Azusa trains is nearby to spot characters moving on the map as the train travels, and enjoy a gamified rail experience unlike any other!
A Celebration of Travel, Characters & The History of Sanrio
This campaign also ties into the opening of the brand-new Yamanashi Strawberry King Museum, blending railway travel with regional tourism and Sanrio’s whimsical world. Dedicated to the founder of Sanrio, Shintaro Tsuji, this whimsically-decorated attraction can be accessed via Ryuo Station (竜王駅) on the Chuo East Line, which is also part of the “Fruit Area” of the aforementioned Stamp Rally.
Whether you’re a hardcore rail fan, a Sanrio collector, or just looking for a unique Japan itinerary, this collaboration offers a fresh way to explore the JR East network—with plenty of kawaii moments along the way.
