The Working Holiday visa application should be submitted electronically to the Swedish Migration Agency via their website.
After the decision is made;
The decision paper will be sent to the embassy or consulate-general you selected in your online application. If you select the embassy in Tokyo, the embassy will send it to your address in Japan by post. So, you do not need to visit the embassy.
If your application is granted, you will travel to Sweden only with your passport and the decision paper and show both at the border control on arrival. After arriving in the country, you must book an appointment with the Migration Agency to have your fingerprints and photograph taken for being issued a residence permit card.
