My comforts to you brother, my favorite location to spend my vacation is Japan, the place is beyond our imagination, they enjoy their life to the fullest, they have traditional cultures and they follow it but they do have an advanced and developed society. 
Thanks, it's "sister" though haha. And Japan sounds wonderful! What is the best place to visit within the country? its on my wife and I's travel list and we want some ideas,
Get a simple place to stay, dont imagine like a star kind of place, just a normal room with AC. The place is cold enough, however you will trave a lot. You can go to Hokkaido, the place where you will see more people and nature, Kamakura with lot of shrines, Enoshima island, Mt. Fuji.
