Whilst many people are familiar with the driving ranges at Lotte Kasai or Jingu Golf Club, some of the smaller ranges often go unnoticed on the roof-tops of buildings throughout Tokyo. In Shibuya there is a range about 5 minutes walk from the station in Nanpeidai.
The website for this range is at http://www.nanpeidai.co.jp
The range is not large as you can see from this photo but if convenience is what you are looking for this is just a short walk from the station and easily accessible. Lessons are available also at the range.
