“Near Tokyo” = 150 km away = “on the same island?”
If you can see it, its near, especially in Tokyo, with our bullet trains, and awesome overground rail and subway system. Mt. Fuji is at least 150km from my place, and I can see it clearly, so its “near”. We’re only talking 93 miles, remember, just about an hour-and-a-half car ride, or a 2-day walk.
