All wallet information is in japanese, I don't know how to create it.
Regards.
Let me explain on how to launch it. I'll be talking about the Windows version.
You will need Java 7 and up to launch the wallet.
First, download the wallet from: https://github.com/koto-dev/koto/releases (Windows and Mac version can be found here.)

Second, run the .bat file located inside the folder.

Wait for the download to finish then proceed to the next step.
Third, execute the WalletUI.jar .

The wallet should look like this:
