How do we remember to count big numbers?

1 to 1,000,000,000

It is more simple to try to remember 1 to 1 billion, using commas.

Japanese numbers are counted from the left, as in English. So, for example

If the number is 12,345,678,
count from ”一千万 /issenman/” to the right. So, it is "一千二百三十四万五千六百七十八 /issen nihyaku sanjuu yon man gosen roppyaku nanajuu hachi".

If the number is 1,234,567,890, it is "十二億三千四百五十六万七千八百九十 /juu ni oku san zen yon hyaku gojuu roku man nana sen happyaku kyuu juu/".
