Mark,
Kawana is easy to find on Google Earth. Just go to the Ito pennisula and scan the coastline for the only golf complex on the shoreline. It is southwest of Tokyo. Great place to relax for a gaijin living in Japan.
Hirono is much harder to find. Infact I have not located it yet. It is near Kobe, which is west of Osaka. If I get to my desktop I might be able to help, but later.
