Mar 30, 2011 Shonen Jump and other manga free online in wake of quake
Due to distribution issues in the wake of the Tohoku quake and its aftermath, the March 14th issue of the massively popular manga Shonen Jump has been made available online for free until April 27 at Nico Nico Seiga (Mac) or Yahoo! Japan (Windows). (In Japanese, but should be easy to figure out.)
Kodansha Comics Plus has also made some of its back issues available online for free through April 30.
