Takeshobo Co., Ltd. (Head Office: Chiyoda-ku, Tokyo, President: Sumitaka Miyata) will hold a major digital book campaign on April 4, 2026 (Saturday) for 24 hours only, where customers can purchase over 1,300 4-koma manga titles distributed digitally for 44 yen (tax included) and at half price through major digital book stores.

Takeshobo's acclaimed masterpieces and buzzworthy works are available at great value during the 'Takeshobo 4-koma Day' event, which is back again this year!

For 2026, '4-koma Day' will be a special version featuring 'Bono Bono,' which celebrates its 40th anniversary of serialization this year!

The comic series, with its 49 existing volumes, depicts the daily life of the sea otter boy Bono Bono with his friends Shimaris-kun and Araiguma-kun, offering plenty to read. The long-running episode 'Ori-chan's Story,' which was highly popular when broadcast continuously on TV anime in 2025, and appearances by the popular character 'Shimacchau Ojisan' are just some of the highlights. With the 50th volume set to be released this July, we encourage you to enjoy the series all at once.

Additionally, we will feature many classic 4-koma works such as 'Obatarian,' which captures the powerful lives of women and became a buzzword, and Masashi Ueda's 'Friten-kun,' which he has been drawing since 1979. Furthermore, we offer a wide variety of popular titles, including those that have been adapted into anime like 'Morita-san wa Mukuchi,' 'Yurumeitsu,' and 'Sensei no Jikan,' as well as 'Makuhari Cactus Campus,' which humorously depicts college life at a fictional university in Chiba Prefecture, and 'Hime no tame nara shineru,' filled with passionate devotion for Empress Teishi by Sei Shonagon.

Reunite with nostalgic masterpieces and discover new favorite works. Please take advantage of this special opportunity to subscribe.
