im planning to go to Japan also but in 5 years
after i finish college and im dragging my friend along with me haha i have to wait a while and save a lot of money so im starting to put aside money kinda hard for me cause i like to shop a lot but its worth it and i want to go shopping a lot there! i think you should bring someone with you so your not alone in a place your not familiar with and about money it all depends on what you plan to do there and how long your going to stay so i hope you plans go well pray for me to haha!
