So, here are the numbers in Japanese! I added an entire lesson on right side as you can obviously see. There is one "number" i forgot to add in which is: zero, rei, 零 (れい) I hope you guys find this useful!
There's a little mistake in the chart, you've put 億 next to the 'juu-man' column instead of 十万, only 百 next to 'hyaku-man' instead of 百万 and 万 next to the 'oku' column. Typo? You have it right on the right side Still, good job creating free resources for people who need them
