Ministers in casual wear

TOKYO, Japan - (From L) Justice Minister Sadakazu Tanigaki, Prime Minister Shinzo Abe and Finance Minister Taro Aso attend a Cabinet meeting wearing "kariyushi" -- an aloha shirt-like clothing item for summertime in Okinawa -- at the prime minister's office in Tokyo on June 4, 2013, in a bid to give a push to the government's "Super Cool Biz" campaign. The campaign, launched the previous day for this year, is intended to promote energy conservation in the workplace by having air conditioners set at 28 C and encouraging employees to dress more casually.
