Notice that there is a specific word for 10,000. This makes it bit more difficult when trying to deal with larger numbers. You have to think of things in terms of 10,000's instead of 1,000's as we are used to dealing with.

You count the 100's, 1000's and 10000's in the same manner as shown with 20-90.
Nihyaku, Nisen, Niman
Sanbyaku, Sanzen, Sanman etc...

With a little practice it will be much easier. It also won't hurt if you are already good with numbers.

It is common to hear original Japanese numbers used in a variety of things. Anything from telling the host/hostess at a restaurant how many people are in your party to asking for a quantity of Big Macs at McDonald's.

Here are the numbers of Japanese origin:

You will also hear the word Yen changed to En at times.
