My fiancee and I are planning

We're trying to figure out where we want to go for our honeymoon and Japan seems to be one of our top options since my fiancee is not big on beaches and doesn't like amusement ride type things(he gets dizzy and sick super fast on them) But looking into pricing going to Japan is quite expensive for us, so what are your options is it worth it? Are there places that are similar worth checking out? Also if you think it's worth it, what's the places that are must visits? (Photo for attention)
