Good luck in your journey. I hope you make it to Japan an it's all that you imagine it will be. It's great that you are taking action, but try not to fall into the trap of believing that if X happens, then I will be happy. Research has show that this is a myth and is not at all the way the human brain works. In reality, people choose happiness first, which opens the door to opportunity and fulfillment, not the other way around. If you have the means, I highly recommend the book, "The Happiness Advantage", by Shawn Achor. http://www.shawnachor.com/the-books/the-happiness-advantage/
