Editorial: Will Tokyo merely watch as US targets ICC chief with sanctions?

The United States has sanctioned Tomoko Akane, the Japanese president of the International Criminal Court (ICC), freezing her assets and prohibiting her from entering the country. This move could jeopardize the international legal system and the U.S. claims it aims to avoid trials for its own officials following actions against Venezuela and Iran.

The U.S., not a member of the ICC, argues that prosecuting nonmember states is an assault on national sovereignty, a stance Japan also appears to share. Despite sanctions imposed on other ICC officials, Japan refrained from condemning the U.S. last year, choosing instead to seek favor with Washington. This response raises questions about Japan's commitment to the rule of law.

The ICC, established in 2002 with 125 member countries, is often referred to as the "guardian of international law." Japan, the largest financial contributor and a significant legal contributor, must support the institution despite this unjust attack. Prime Minister Sanae Takaichi has vowed to strongly support Akane, but now it is crucial for Japan to turn this promise into action.
