To renew your Japanese working holiday visa
(I renewed/ extended mine twice in Okinawa 2014 and 2015 respectively as an Australian.)
1. Ring up or visit the local immigration office in the area you live in to check what documents you need in advance.
2. Prepare and bring all the documents such as residence card, passport, and the application form with reason (s) considered or pre-filled in advance how you justify the reason for the renewal/ extension.
3. Go to the local immigration office and pay the fee, 4000 yen.
4. Wait for the processing time and there you go. (Please the tips below.)
-You can renew / extend it 3 months prior to your expiry date.
e.g. Expiry date is on 5th July 2015 then you can renew it after 5th April 2015.
-Just to make sure you get the right information, it is strongly recommended to call the local immigration office the area where you are staying and go to see them to cross reference what you need for renewing your visa as instead of just sticking to the guidelines that The Ministry of Justice provides.
-The first time you renew you can get the result and the new residence card on the same day.
However, the second time you do it, the process will be around 2 weeks to 1 month.
