This article reports on what Prime Minister said in the Japanese Diet (or Parliament) as below.

In Tokyo, the Japanese government pledged closer cooperation with Washington and Seoul to counter North Korea.

Prime Minister Naoto Kan, speaking in Parliament, noted that for the first time since the Korean War of the early 1950's the North Koreans fired at a place where South Koreans live.

Mr. Kan says the attack is extremely grave and has put the Korean peninsula on the brink of war. Severe action, he adds, needs to be taken to punish North Korea.

The above report sounds like Japan is going to take a very serious measure against North Korea. However, when PM Mr. Kan was asked to clarify his statement by Mr. Itchita Yamamoto, Liberal Democratic Party member, he was unable to specify what he meant by his statement at all.

Mr. Yamamoto said to PM Mr. Kan "As I believe the economic sanctions taken against North Korea by Japan have already been the severest, I demand PM Mr. Kan to specify any other economic sanctions severer than already taken against North Korea.
