Hi, we are visiting Japan for the first time in April my wife & I are on a bike/cruise ending in Osaka and need to get back to Tokyo Int Airport. To make the most of our visit at the end of the trip we are thinking of cycling Osaka to Tokyo we would be on a loaded tandem, would it be worthwhile trip - not all main roads & traffic. Or if we went somewhere else to explore & cycle can a tandem be taken on the trains. Any advice would be greatly welcomed and is there a cycle route map available online Many thanks for any help or information.
