Chief Justice John Roberts Jr., who has called the U.S. Supreme Court “unique” among the world’s top courts, will connect with another singular tribunal when he visits the Supreme Court of Japan in July.

Both courts announced on March 27 that Roberts will visit at the invitation of Chief Justice Itsuro Terada and the associate justices “to discuss matters of common interest.” Japan’s chief justice visited the U.S high court and met with the justices in 2012.
