Don't hesitate!
Do not hesitate to ask around! There are so many services around you that are willing to help you get to your destination. I recommend either 1) Go to the information desk at the nearby mall or department store, 2) go to the police station or 3) ask a foreigner (or local) on the street (they may be living in Japan)! These are simple steps that you can take to make your visit to Japan easier and less worrying!
