Greek Japan

It appears there might be a misunderstanding in the country name provided. 'Greek Japan' is not a recognized sovereign nation. Greece and Japan are two distinct countries, each with its own unique visa policies, cultural characteristics, and geographical locations. Therefore, I cannot provide a visa overview for a country named 'Greek Japan' as it does not exist.

If you intended to inquire about either Greece or Japan, please specify which country you are interested in, and I would be happy to provide a comprehensive visa overview for that specific nation. Both Greece and Japan are popular travel destinations with well-defined visa regulations for visitors from around the world.

For Greece, as a member of the Schengen Area, its visa policy follows the Schengen agreement, allowing for visa-free travel for many nationalities for short stays, and requiring a Schengen visa for others. Japan, on the other hand, has its own bilateral visa waiver agreements with numerous countries, permitting visa-free entry for tourism for varying durations.

Without clarification on which country you meant, I am unable to provide specific details on visa types, processing times, or any recent changes to visa policy, as such information would be entirely speculative for a non-existent entity.
