Along with the March 21 earthquake and tsunami that walloped the country March 11, Lavigne’s announcement also cited the country’s ongoing crisis with the Fukushima Daiichi nuclear plant as a reason for postponing the tour.

Lavigne’s “Black Star Tour” was scheduled to play Fukuoka May 16; Osaka May 17-18 Saitama-shi May 21-22 and Nagoya May 24. While those shows are off the books until further notice, Lavigne says she will reschedule the dates.

Lavigne is also donating proceeds from Amazon sales of her single “Keep Holding On” to the American Red Cross Japan. For more information, visit AvrilLavigne.com.
