Any considerations when using Japanese? Tags, fonts, SEO

[patent10021]

I'm in Japan and want a WP site that allows me to design and blog in Japanese & English. I've never had any issues before and I just went ahead and designed in a default Japanese font.

But what if I want to use special Japanese designer fonts and don't know CSS etc? Do WP themes let you use any fonts you want?

What about search Engines in Japan? Do I need to insert special meta tags or other info to comply with Japanese SEs?

If this is a WP site, i bet you can find plugins to help you out, I know for a fact that the "All In One SEO Pack" plugin lets you add SEO info to each post so you could add information in Japanese for your Japanese posts and English for your English posts.
