Japanese fonts for Mac OS X 10.5

Looking for gyosho type Japanese fonts for Mac OS X 10.5
The ones that come with the system are nice and all, but I'm in need of something more stylish.
Which is something the semi-cursive gyosho style font would provide.

I haven't been able to find any Japanese fonts to install on the Mac at all, with the exception of the Japanese Font Pack for OS 9.

I have no interest in paying over $500 for some professional level font pack which will include a lot of fonts I'll never use, but $20 or so for a single font I like, is fine.

Any suggestions?
