Typing Japanese characters.

I have communicated with penpals and friends in around the world in through italki,_skype, or anything other (online) tools {or things} in for a while._Sometimes, I'm asked how to type a Japanese character on them computer._Now that you say thatmention it*, I have never known how to set up a computer to type Japanese characters.Because in Japan,_the computer was already set up when I bought thatit._I can't explain well, about Ime it's built into the software {should really be "operating system"}._One more thing,_we Japanese people have a special keyboard,_but most of them don't use Hiragana input._You know** we input Japanese characters by using {or "through"} Roma-ji input.

*"Now that you mention it" is an idiomatic expression. Another similar to it is "Come to think of it"; it sounds less direct than saying "you".

**This reads quite familiar", I think it's better to say "In fact, we input..." or "Actually, we input"

General note: Please pay attention to adding a space between the last sentence and the beginning of the next.
