Characters from 12 Kodansha manga series, including 'Attack on Titan' and 'Blue Lock,' to introduce Japanese etiquette to visitors

We sincerely appreciate your continued understanding and support of our publishing activities.

Starting Monday, March 30, 2026, Kodansha will launch the 4th installment of its "MANGA MANNERS" etiquette campaign, featuring globally popular manga series, within Tokyo Metro and Tobu Railway stations and trains. This edition welcomes three new titles—"Atelier of Witch Hat," "Darwin's Incident," and "Space Brothers"—and introduces new etiquette guidelines aimed at helping international visitors enjoy a comfortable experience on Japan's railways.

"MANGA MANNERS" first debuted in October 2024 as a massive welcome wall at the immigration area of Narita Airport Terminal 2. Following its positive reception, the second installment was launched in April 2025 at Tokaido Shinkansen stations, anticipating high traffic due to the Osaka-Kansai Expo. The third installment followed in November 2025 in Kyoto, one of Japan's premier tourist destinations. This fourth installment will now be featured across the Tokyo Metro and Tobu Railway networks.

As with previous campaigns, we have consulted with Tokyo Metro and Tobu Railway to address specific railway etiquette challenges. New guidelines include: "Please refrain from taking photos that may disturb other passengers in stations or on trains," "Please set your phone to silent mode and refrain from making calls on trains," and "Please keep the area near the doors clear when boarding or alighting." Including continuing themes from previous campaigns, a total of 12 manga series will present 12 etiquette guidelines. We hope that not only international visitors but also regular commuters will enjoy learning about Japanese railway etiquette through this campaign.
