TOKYO — Organizers of Anime Contents Expo, a new toon market skedded for March 26-27, have canceled the event.

Among the reasons given were rolling blackouts that might disrupt transportation to and cut power at Tokyo’s Makuhari Messe event space, the event’s venue, as well as the worrisome situation at the damaged nuclear reactors in Fukushima that might impact the safety of visitors.

The Thursday announcement comes on the heels of Wednesday’s cancellation of the rival Tokyo Anime Fair, originally set for March 24-27.

Anime Contents Expo was launched by publishers, toon houses and other companies opposed to tighter restrictions on sexual content in comics and toons approved by the Tokyo city legislature last December, with the support of the Tokyo metro government. Since the Tokyo government is also a sponsor of TAF, the protesters not only called for a biz boycott of TAF, but started their own toon contents mart, ACE.

Among ACE organizers are Aniplex, Animate, Kadokawa Publishing, King Records, Geneon Universal Ent. Japan, Frontier Works, Marvelous Ent. and Media Factory.
