First big checkpoint: 箱根宿(Hakone inn town)
In this route if Hakone, Google map shows 3 Tokaido routes, which is confusing. First, there are two National R-1s. R-1 bypass route goes further southeast down. And another R-1 comes down from Kowakudani, via Motohakone then joins again with old Tokaido route. Second, it’s Kanagawa prefectural R-732 which goes parallel to old Tokaido route. Then you see old Tokaido route aka 旧東海道(Kyu-Tokaido). However, look at the next picture. There are two “Old Tokaido” routes. I have not figured out how this happened. This is one of fun things to figure out by visiting Hakone and asking a local guide about. Mountain part of Tokaido trail in Hakone is vastly untouched, or well-preserved. Cedar tree trail part(which I circled red), is definitely beautiful. There is no street view on this part, however, go online with “Tokaido Lake Ashi cedar tree” and you will find a lot of pictures and videos. You eventually end up joining National R-1, then soon you are turn...
