MATSUE, Shimane Pref. (Kyodo) Shimane Gov. Nobuyoshi Sumita announced Friday he will send to South Korea's North Gyeongsang provincial authorities copies of a quarterly magazine the prefecture publishes that reiterates Japan's claim to South Korean-controlled islets in the Sea of Japan.
The magazines will be sent to South Korea by Feb. 22, the day designated by the prefecture last year as "Takeshima Day" to underline Japan's claim to sovereignty over the islets, which South Korea refers to as Tok-do.
The territorial issue has been a key source of friction between the two countries in recent years.
