This is Sterculia brevissima at Koishikawa Botanical Garden in Tokyo. It's native to the Yunnan province of China and written as '短柄苹婆' in Chinese. Because it is so rare in Japan, it has no common Japanese name and very little information available. Still, these star-shaped white and pink flowers are too cute to ignore!
