The convenient way for getting from Tokyo to Osaka is by highway bus!
Not only is it considerably cheaper than the bullet train or plane, but the amount of the destinations available make it a worthwhile alternative.
We have buses going to Umeda (the center of Osaka), Namba (popular with foreign tourists), the gigantic Rinkuu town outlet store near the airport and the crowd-pleasing Universal Studios Japan.
With a wide range of locations available for you to choose your favorite from, we recommend it.
Highway bus takes about 8 hours (Actual times vary by bus) which can allow you to get some sleep and taking the night bus can also save you the cost of one night in a hotel.
