Jul 07 (Solo Travel Japan) - I took an extremely comfortable bus from Niigata to Tokyo Japan. The bus has only 18 seats on board. The seats are spacious.
The bus is called Reborn, operating by Willer Express. Willer Express offers more than 120 routes throughout Japan. You’ll find the same bus on the route like Tokyo and Osaka. The price was 3,500 JPY (32 USD), but the price is really depending on the season.
