Publisher Shogakukan formally announced on Friday that it has decided to suspend the publication of its Weekly Young Sunday manga magazine due to a long decline in sales. The magazine once had a circulation of around 800,000 in the early '90s, but in recent years it has fallen far behind rival magazines and is now averaging only about 200,000 copies.

Young Sunday premiered in 1987 as a semimonthly publication, but it switched to a weekly format in 1995. Currently, it is the home of popular mangas "Dr. Koto's Clinic" and "Kurosagi," among others. The magazine's last issue will go on sale July 31.

Shogakukan is also suspending its women's magazine Judy after August 23 and is revamping its information magazine Rakuda.
