In Japanese it is very easy to construct numers from single digits. The procedure is very straight forward. Unfortunately, it gets more complicated when counting objects, because certain qualifiers must be used. Let's start with digits, the easy part.
To build larger numbers, the following building blocks may also be needed:
It can be noticed that the Japanese counting is not based on the power of thousands (million, billion, trillion), but on the power of hundreds.
The above tables contain the essential building blocks. They are the elements which build all other combinations. Here are some self explanatory examples:
The above examples show that the Japanese number building makes perfect mathematical sense.
