Someone posted this resource on Tae Kim’s facebook group:
Although I’ve been living in France for two years and use numbers in French on a daily basis, I still regularly get tripped up over them. And I have the same problem with Japanese. This website seems like a good place to get some practice listening to Japanese numbers.
EDIT:
Actually there is already a post here which was made by @hunterbridges, the creator of this resource ![]()
