Tragedy has struck the manga world with the sad loss of Yoshito Usui, who died after falling a terrifying 300 feet off a cliff while hiking in the mountains in my home prefecture of Gunma. Usui is the creator of Crayon Shin-chan, the spirited kindergartner who is often called the Bart Simpson of Japan, and the manga-ka created comics featuring his trademark characters every month since 1990. Combining sharp-witted humor and interesting social commentary from the point-of-view of a five-year-old, Crayon Shin-chan won fans all over the world, from India and China to Spain and the Netherlands as well as the U.S. While I've enjoyed reading the series over the years, Crayon Shin-chan can be a challenge for parents, since kids love to copy his bad behavior, exposing their butts and calling their mothers by their first names, or asking embarrassing questions like, "Why does the box of tissues in Mom and Dad's room run out faster than in any other room in the house?" Mr. Usui's cause of death is not yet known. Although there was no suicide note or any direct evidence to believe the artist wanted to die, some of the themes in his manga had been causing some to wonder about his mental state, for example a story he drew in 2007 in which the fiancee of the teacher Ume Matsuzaka was killed in a terrorist act while overseas, forcing Matsuzaka to contemplate suicide herself.
