East Asian languages treat 100,000,000 as a counting unit, significant as the square of a myriad, also a counting unit. In Chinese, Korean, and Japanese respectively it is (simplified Chinese: 亿; traditional Chinese: ; pinyin: ) (or Chinese: 萬萬; pinyin: wànwàn in ancient texts), eok (억/億) and oku (). These languages do not have single words for a thousand to the second, third, fifth power, etc.
