To get to Gunma Prefecture, it is an about 1-hour ride from Tokyo Central to Takasaki Station on the JR Joetsu Shinkansen Line, then about 10 minutes from Takasaki Station to Maebashi Station by JR Ryomo Line. If you are coming from Osaka, it’s bout 2 hours and 30 minutes from Shin-Osaka Station to Tokyo Station by Tokaido Shinkansen Line.

If you are headed for the ski resort areas, take the Joetsu Shinkansen to Jomo Kogen - which takes about 60 minutes - and then make your way to the resorts by bus.

It is possible to avoid the Shinkansen by using the local trains from Tokyo, though the journey time will more than double.  To do this, use the Takasaki line and then the Joetsu line (which continues up through Yuzawa and beyond in Niigata Prefecture).

For the resorts in the Minakami town area, get off the Kanetsu Expressway at the Minakami I.C. and go from there using Route 291.

Take the Kanetsu Expressway and exit at the Shibukawa-Ikaho I.C. From there, take Route 17 to Route 353 to Route 145 and finally to Route 292, which will take you to Kusatsu Onsen.
