Debuting its new menu items, Starbucks Japan has three new treats (the matcha butter sandwich (335 yen), the matcha cream doughnut (295 yen), and the rice flour matcha roll cake (445 yen), which customers can order at the checkout today. Apparently, the salty butter and matcha-flavoured red bean paste is solely available at select drive-thru locations. The menu items are now available in Japan for purchase.
