Have you figured out how to get your computer to type in Japanese yet?

If you don't know what kind of computer you have, ask your parents. If your computer isn't listed here, feel free to comment what kind of computer you have and I'll write a guide for it.

Once you have it set up, practice writing こんにちは (hello). こんにちは is typed like this: ko nn ni chi ha. The ha, however, is pronounced wa.
