Twinkle bus in Biei and Furano in summer?

Anyone knows if twinkle bus still operates tours in summer in Biei and Furano? I tried searching but does not seem to have any updated information. Thank you very much!

I don't think they are called "Twinkle Bus" anymore. But there are similar sightseeing buses. They are explained here:
