Teaching in Japan to bolster my CV/ resume and get language and cultural experience?

I have a BA in Asian Studies with a TEFL concentration and minor in Japanese. My plan is to apply to JET and teach for a year or two or whatever, and then come back and hopefully use that experience to try to get a research associateship for a master’s. Is this a good plan? My ultimate goal is to teach at the University level. Any tips or thoughts are appreciated.
