There are over 200 sculptures, the biggest of which is a Star Wars themed spectacle, which organisers say was created using 850 truck loads of snow and ice!
They expect more than two million people to visit the festival, which runs from now until 11 February.

Ball, who featured against Pakistan A in Dubai, has taken six wickets in each of Notts' first two games and is the leading wicket-taker in Division One of the County Championship so far in 2016.
Read said of the 25-year-old: "Last winter he got fitter and stronger.
"Now he's genuinely lively and he does plenty with the new ball."
Read said Ball's assured early showings have demanded he lead Notts' bowling attack with the new ball alongside England's Stuart Broad.
"Jake is in fantastic form with the ball," continued Read. "He's had a great winter having been in Dubai with the Lions and has had a taste of what life is like with the ECB set-up. He's really keen to progress that side of his career."
Notts director of cricket Mick Newell said Ball, who was their second-highest County Championship wicket taker with 39 last season, said he has been "terrific" so far in 2016.
"That's a fantastic start to the season and he's setting a great example," added Newell.
Despite Ball's efforts against Lancashire, Notts suffered an eight-wicket defeat in their second Country Championship match of the season on Wednesday, having beaten Surrey in their opening fixture.

A total of 1,400 tickets have sold out for the opening weekend at Bramall Hall in Stockport, Greater Manchester after renovation work began in 2014.
Stained glass windows and ceilings have been restored, while the public will be able to visit the dining room and butler's pantry for the first time.
Councillor Kate Butler, from Stockport Council, called it the "jewel in the crown" of the town's heritage.
The manor dates back to the reign of William the Conqueror when he bestowed the lands upon one of his followers, Hamon de Masci, who became the first Baron of Dunham Massey.
Since then the estate has been under the ownership of just three families: the Davenports, De Bromales and Nevills.
In 1936, the timber-framed hall and its surrounding parkland was handed over to the local council.
The transformation followed a £1.6m grant from the Heritage Lottery Fund and £400,000 in council funding.
