A wrapped train from Ibaraki Prefecture's collaboration with the anime The Apothecary Diaries runs on the JR Yamanote Line from November 13 to 26, 2026, Anime Anime reports. The designs show Maomao, Jinshi, Basen and Lahan alongside seasonal attractions from the prefecture.
The campaign uses one 11-car train set, with artwork on both sides of cars 1 through 11. There are five designs: one each for spring, summer, autumn and winter, plus a key visual that brings all four seasons together. The artwork shows Ibaraki's flowers, nature, food, festivals and activities. Each design includes tourist spots, local products and experiences tied to its season.
The train is part of a wider tourism promotion that Ibaraki is running with the anime under its tourism brand concept "IBARAKI is Blossoming." The prefecture is also running a stamp rally at tourist spots, offering AR photo spots and selling original merchandise with newly drawn illustrations.
The train may be taken out of service at times during the run, and it may not operate on November 26 because of removal work. The announcement asks fans not to contact the railway company or station staff about the train set or its schedule.
