Getting to Mimamiuonuma
Getting to Minamiuonuma is a very simple journey from Tokyo - both by train and car.
The Kanetsu Expressway (toll road) runs through Minamiuonuma. The journey from Nerima I.C. in northern Tokyo to Shiozawa Ishiuchi I.C. is about 185km and in good conditions can take around two hours. (Please note that in bad weather conditions and peak times, it can take considerably longer). The journey takes you north through Saitama and Gunma Prefectures, under the Tanigawa mountain range in northern Gunma, through Yuzawa and into Minamiuonuma.
If you are planning on visiting the resorts in the Shiozawa and Ishiuchi area, get off the Expressway at Shiozawa Ishiuchi I.C.
If you are planning on visiting the resorts in the Muikamachi and Urasa area you might want to get off the Kanetsu Expressway at the next Interchange - Muikamachi I.C.
Many people visiting Minamiuonuma by train use the Joetsu Shinkasen (bullet train) that stops regularly at the nearby Echigo Yuzawa Station. The train from Tokyo takes on average between 75 to 85 minutes to Yuzawa.
You can take the local train (Joetsu line) from Echigo Yuzawa Station to the stations in Mimamiuonuma - Ishiuchi, Joetsu Kokusai Skijo Mae, Muikamachi.
Alternatively on exiting Echigo Yuzawa Station you will find shuttle buses going to most of the main resorts. The journey from the station to resorts in Mimamiuonuma takes between 10 minutes and 40 minutes.
From Narita International Airport (About 4 hours)
From Narita International Airport, you will first want to get into central Tokyo using either the Narita Express or Keisei Skyliner - both take around 1 hour.
The Narita Express goes direct to Tokyo Station, and from there you can easily transfer to the Joestu Shinkansen.
The Keisei Skyliner goes to Keisei Ueno Station. From there it is a 5 minute walk over to the JR Ueno Station where you can also catch the Joetsu Shinkansen.
