The rented car has GPS in Japanese but I don't read Japanese so depend on the entering of telephone numbers to get to each destination. My issue is for driving within Hakone is that I am not sure how to get the telephone numbers of the sightseeing locations. We'll be setting off from Pension Hakone to Owakudani (‘å—O’J) to view Mt Fuji and visit the sulphuric valley.

Could we have the telephone number of a shop located there to key into GPS or is a driving map available online?

Are there any recommendations on other sightseeing/food places to visit accessible by car in Hakone? Thought we might as well take advantage of the car since we have it. We'll be there on a Thurs/Friday so hopefully traffic is quiet as many had commented on this forum.

We got our rental car in Gotemba and also went to Gotemba Premium Outlets and Grinpa Park. Mapcode for the Outlets is 50 805 506 with 3500 free parking. I couldn't locate the mapcode for Grinpa Park. Their phone no. is 0559-98-1111 and here is an access map: http://www.grinpa.com/access/index.html
