Park Golf (パークゴルフ) is about halfway between real golf and putt-putt golf and is hugely popular in Hokkaidō, mostly with retirees. You can't drive far without spotting a sign for one of the meticulously manicured courses. There are usually nine holes covering an area of about three or four football fields. The holes vary in length from about 40m to 80m – just like real golf, par 3s are shorter and par 5s are longer – with bunkers and greens. You are, however, only allowed one club and the ball is hard and sized halfway between a golf ball and a baseball. It's good fun – and doesn't have the same strict level of etiquette as proper golf. Most local courses charge from ¥300 to ¥500 to play and a little more for a rental club and ball; one round should take around 1½ hours.
