Snow Peak, the outdoor products company based in Niigata, has excellent camping facilities (see Don's write-up on the camping page) at its corporate headquarters in Sanjo. I cycled over after work in neighboring Tsubame on Friday of last week for the first overnighter of the year. Some campgrounds charge as little as 500 yen/ night. At 1,500 yen Snow Peak is at the upper end of the scale. However, the facilities are well-maintained, and it's hard to beat a hot shower at the end of a day of cycling (not all cheaper campgrounds have showers, and none are likely to have ones as nice as those at Snow Peak). Off the scale is the price of a can of beer in the camp shop; if you are going to imbibe, definitely stock up at the supermarket in town, which you'll probably be patronizing anyway for your edibles. I loaded up on fried pork cutlets, or tonkatsu, to add to my keema curry.
