Koji Seo‘s new manga Umine the Island Inn has begun serialization as of January 14 (JST time), and the first chapter can be found online in English on Kodansha’s K Manga service. The romantic comedy sees its protagonist starting a job at Asagiri Island’s Umine Inn, surrounded by a cast of attractive women.

Umine the Island Inn (Ano Shima no Umineso) is serialized in Weekly Shonen Magazine in Japan.

The synopsis reads:

Unemployed 19-year-old Kazuma has been summoned to Asagiri Island, rumored to be home to long lost pirate treasure. He ends up working as an odd-job man at Umine Inn, a traditional Japanese café with women-only lodgings and a host of eccentric yet beautiful women. The stuff of dreams for any man – a romantic comedy about island life and treasure hunting, where the surroundings are beautiful in more ways than one! ” 

Seo’s previous works include Suzuka, Fuuka, and The Café Terrace And Its Goddesses, which have inspired TV anime. The Café Terrace And Its Goddesses, a harem romantic comedy where its protagonist decides not to sell his late grandmother’s café due to the five women who live and work there, released its 21st and final volume in October 2025.
