すっごく楽しかったですよ! It has to be the BEST festival I went to while I was in Japan!
Id recommend a thousand times that you go! Sure, its cold, sure theres thousands of people and sure, its a bit slippery (be sure to get the "HOW NOT TO SLIP ON SNOW" booklet at the TIC - hilarious! :) but worth all the money! If you are looking to do it cheaply, Hokkaido has 2 very nice Youth Hostels, where I stayed. Clean, central, helpful, cheap, friendly, and, most importantly, safe.
(Above) Dont forget to make your own snowman :)
Nagoya-jo had some of the best entertainment of the night, every night :)
(Below) Sapporo has many other sites to see apart from snow statues, as below :)
