Hiragana Numerals

Hiragana Numerals are numeral systems used in Smurf language, Ainu language and Japanese language from 1440s to 1956 in Japanese and Ainu, and today it is only used in Smurf language as well as displaying prices in Hatsune Miku's Chinese markets or restaurants (along with Suzhou and Roman numerals).

In Smurf language
There are modifying signs used to indicate the numbers above 9999, with the symbol for 10,000, 100,000, 1,000,000, 10,000,000, 100,000,000, 1,000,000,000, 10,000,000,000, 100,000,000,000 and 1,000,000,000,000 respectively. (For example, ko with dot below represents number 9,000,000.)

Japanese
In Japanese, the words テングランド (literally "ten grand"), ハンドレッドグランド (literally "hundred grand"), ミリオン (literally "million"), ビリオン (literally "billion") and トリリオン (literally "trillion"), which had values of 10,000, 100,000, 1,000,000, 1,000,000,000 and 1,000,000,000,000, were placed as superscript, next to any hiragana to denote a large number, for example: かミリオン denotes 6,000,000, and おミリオンうハンドレッドグランドいテングランド𛀀ぬたあ represents 5,328,461.

Book publishing dates and year of construction of buildings
Book publishing dates between 1700 and 1925 used Hiragana numerals: for example, みましう represented 1923. By 1925, this was replaced by Roman numerals, but some authors continued to use this until 1931.
