Praise be! I just finished my visa renewal and I got a three year extension. Now I can finally quit Novacation (work it out, the company's name is the first 4 letters) and score me one of them there sweet teaching gigs I hear about!
If you ever need to renew your working visa in Osaka, go to the office in Shitennoji (四天王寺）; not the one in Tenmabashi. You're chances of getting a three year renewal increase. It's on the purple Tanimachi subway line at Tennoji (天王寺) station; leave from exit one and walk for 5 minutes to your right.
I'm off to celebrate with the many bottles of booze Karaoke Queen and Osakaotaku gave me. CHEERS!
