OK, I guess you are quite young then. If this is the case then do not fret as you have pleanty time excluding an un-natural death. (JOKE)
IF I were you and I reached the age of 20+ I would seriously get a a group of like minded friends together for a trip, If it came down to me having to go on my own I would say "buck it" and go on my own as I know I would make new friends in Japan.
I would say on reflection that I would even consider coming to Japan if I were 18. Fortunatly I am now an old man and I can do what I want whithout any issues. In one way it is good but being an old man is like -300 hp in kudos points. What I would have given to reverse time and be here when I was 18.

Back to reality and the fact that I can afford the best maid cafes hehehehe!
