I choose no.4.
If I were a guide of Japan, I would like to take Hokkaido, Tokyo and Kyoto.
I think these places have different characteristics.
First, Hokkaido has Mother Nature, delicious sea foods and wonderful hot springs. Furano is famous for “From The North Country (北の国から) ” It is a popular Japanese TV drama. There are a lot of lavenders in a vast plain. So you can be relaxed to see their flowers and their fragrances. My hometown Hakodate’s sushi is very delicious!!! Fishes and shellfishes are so fresh. Once you eat sushi in Hakodate you won’t to be able to quit!! I love a hot spring especially Noboribetsu’s one! This is muddy water and it makes our skin more beautiful! Everyone surely enjoy come to Hokkaido.
Second, Tokyo has urbane buildings which have many interesting shops and everyone can enjoy an atmosphere of metropolis. There are many limited goods in Tokyo so if you would like to have rare goods, you have to go to Tokyo and buy it. And I want to take to Harajuku because there are NEW Japanese cultures (kosupure, bakudanyaki and so on…)
Finally, if you would like to experience about Japanese cultures, you have to go to Kyoto. There are a lot of temples and shrines and you can enjoy drinking traditional Japanese tea (Maccha) with Japanese sweets on tatami. And you can transform yourself into maikosan! It’s a very good experience!!
Hokkaido, Tokyo and Kyoto have many good points so if I could be a guide, I would like to take visitors to there.
