Utsunomiya is about 40 minutes from the Tokyo metropolitan area by bullet train and less than two hours by conventional train.
It is possible to come to Utsunomiya by train if you only want to go around the station, but if you want to go to the suburban areas such as Otani Museum or Nikko, it is more convenient to drive.
Basically, the best way to get to the arena from JR Utsunomiya Station is to walk. Take the east exit of Utsunomiya Station and walk.
The atmosphere in front of the station at the east exit is a little more relaxed.
There are many stores at the west exit, so if you want a quieter exit, the east exit is the way to go.
Next to the arena, there is a unique building called Tochigi Prefectural Utsunomiya Industrial Exhibition Hall "Marronnier Plaza".
This building is more unique and conspicuous than the arena.
