His hometown of Dubnica nad Váhom is just a three-and-a-half hour drive from Košice where Tatar and the rest of the Slovakian contingent will open preliminary round play against the United States at Steel Arena on Friday night.
This marks the 28-year-old left-winger's fifth appearance at the annual event, and his first since 2015.
"I am very pleased to be back in Slovakia. After a long break, I can wear a national jersey again. It's great motivation with the World Championships being at home," said Tatar, in a Slovak Ice Hockey Federation Instagram post late last month. "It's something special."
Over the years, Tatar has registered eight goals and 17 points in 29 tournament games.
He claimed a silver medal in 2012.
