There is considerable Olympic experience in the field with Calgary having hosted the 1988 Winter Games and Sapporo having staged the 1972 edition.
Candidates willing to host the Olympics, especially the Winter Games, have become fewer in recent times due notably to the rising costs and security concerns.
There are seven serious bids on the table: Calgary, Canada; Stockholm, Sweden; Graz, Austria; Sapporo, Japan; Sion, Switzerland; Erzurum, Turkey and a combined bid from Milan and Turin in Italy.
The Turkish city of Erzurum believe they are "fully prepared" to host the 2026 Winter Olympic and Paralympic Games after their interest was officially confirmed by the International Olympic Committee (IOC) yesterday.
The Executive Board will then recommend which cities to invite to bid, and the IOC Session will vote to approve the list. Cortina is also a former host, having organized the 1956 Winter Olympics, with Turin hosting in 2006.
The IOC will allow cities to begin bidding in October with a January deadline.
He added in a conference call from Lausanne, Switzerland, that it also helps if the city regularly holds World Cup events and world championships.

Riyadh has repeatedly accused the Houthis of acting as a proxy force for Shia Iran, Saudi Arabia's arch-foe in the region. The airstrike hit a compound housing displaced people in the town of al-Hami.
The IOC has tried to attract more bidders after only two candidates reached the vote for the 2022 Games.
"I warmly welcome the NOCs' and cities' interest in hosting the Olympic Winter Games", IOC President Thomas Bach said.
A official candidature phase follows until September 2019.
Dubi said it's important for Calgary to make sure that any budget put forward is strong and down to the last detail.
The cost in Calgary of making a formal bid for the Olympics is about $30 million and the Calgary Bid Exploration Committee concluded past year that hosting the 2026 Games would cost $4.6 billion.
But he said those involved must be realistic when working out the numbers.
