My husband and I live in Japan and we're planning to travel to South Korea this June. We both hold a Philippine passport with a long-term resident Japanese visa. Do we still have to apply for a visa at the immigration or can we just do it online?
As stated by Timatic, the database used by airlines:
Visa required, except for Nationals of Philippines with a visa issued by Australia, Austria, Belgium, Canada, Cyprus, Czech Rep., Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland (Rep.), Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, USA or United Kingdom if in transit through Korea (Rep.) [for max 30 days].
Japan is not in the list. So unfortunately, you do need a visa
