Zoo official say Kobe is seven years old, as is Koda, a male bear already at the zoo who is considered to have just reached his "prime" mating years.
The animals are being kept in side-by-side rooms when they're not on display at alternating times in the zoo's polar bear tundra display area.
Zoo officials tell the station the bears will eventually be allowed to share space in the "hope that love grows."
Polar bears usually breed from March to June.
