Sorry I know how to write it, but unfortunately my laptop doesn't have Jap IME.
That does say mitsubishi, but there is a cool kanji for it. Starion is usually written in katakana, there is no kanji for it. (from memory, I can't read it on this laptop, but at work I can, my signature should say Starion.
The 'ka' kanji means power, or strength. If Anthony hasn't got back to you, I will help you out tomorrow.
your better off getting the Calligraphy of the kanji done. The strokes are usually done in a specific order and direction, changing them to us, would look normal, but to them, they would laugh at you.
The ones at the top of your post is the calligraphy type, and it can get messier and messier. I personally like the ones at the top, they look nice.
You can look up the kanji stroke orders for some of these if you really try. That can give you an idea of how you would want to put it, or get Mr Ralliart (anthony), his wife or himself might be able to do up a really nice calligraphy poster of it.
