Tanak opened a 9.1sec lead over Ogier in a Citroen and is 14.3sec ahead of Belgium's Thierry Neuville in a Hyundai.
"I guess everything at this rally is a kind of a surprise and it's difficult to expect anything," said Tanak after the two stages run on studded tyres to combat the frozen ground.
"Some places were even more slippery and tricky than we expected."
Loeb, fresh from a third-place finish on the sand dunes of the Dakar Rally in Peru, could only manage eighth in another factory Hyundai.
The French driver, who is competing in just a portion of the 2019 world championship, hit trouble on the second stage of the day and finished more than 55 seconds off the lead.
Ogier was the happier of the two French drivers as he chases a seventh win on the storied rally, the curtain raiser to the world championship season.
"I'm happy to be here, we all knew it was going to be a tricky start," tweeted Ogier who has won the last six world titles.
"Maybe we were a little bit too safe on the icy places in SS1 but we managed to do a good time on the dry with crossed tyres, and overall it's not a bad start for us."
Finland's Teemu Suninen, in an M-Sport Ford, came off the track on the opening stage and was the first day's only retirement.
