ANA does direct flights from Chitose to Rishiri. That's who I've flown when I've previously visited, as it was way more convenient from Tokyo. Those flights are also timed well in that the closest incoming flight arrives at a nearby gate for the outgoing flight to Rishiri.
JAL (Hokkaido Air System) does Okadama to Rishiri.
