Does it matter if the visa is refused in Europe and then signed in Japan?

There must be some influence, and it is useless to change your passport, because if you change your new passport, the old passport will be handed over to the embassy together, and even if you make a report on the loss, the embassy can find it.

I specialize in outbound travel in international travel agencies. I suggest that you don't sign Japan this year, because you may just get married and your job is not very good, and the embassy will be suspicious. And if Japan refuses the visa again, it will be very difficult to go abroad in the future.

I suggest that you choose to spend your holiday in Southeast Asian islands this year, such as Bali, Maldives, Saipan, or areas where visas are relatively easy, such as Malaysia, South Africa, Egypt, Australia and New Zealand, because the rights of group tourist visas in these two countries have been delegated to chartered travel agencies, and as long as the travel agencies accept your materials, they will generally not refuse them. You can consult the largest local international travel agency for details.

Personally, I suggest choosing an island tour, which is easy to get and suitable for honeymoon.
