Japan Tourism Agency Commissioner Hiroshi Mizohata sang the South Korean national anthem Tuesday in Seoul in an effort to win the hearts of Koreans and lure tourists back to Japan.

The number of South Korean tourists to Japan has fallen sharply amid the Fukushima nuclear crisis that started 11 March.

While the overall number of foreign tourists has recovered to levels seen before the crisis, the uptick of inbound South Korean visitors has been slow, according to Japanese government data.
