I am currently in Sapporo now and about to make a trip to Furano for a night stay.

However, I am not sure if I should purchase the JR Furano Biel Round Tour Ticket or buying everything separately.

I will be staying at Furanui pension and planning to go to Farm Tomita, Cheese factory, Jam factory, Ningle Terrace etc.

My earlier research is taking the local bus called "Lavender-go-bus". Is it the same as Twinkle bus? I am getting abit confused with Kuruku bus, Twinkle bus and Lavender go bus.

Should I get the JR pass?

Twinkle Buses are tour buses that visit several sightseeing spots along the way. There are multiple lines:

And the Lavender Go bus is a regular bus line, that connects Furano via Biei with Asahikawa.

Thanks for your quick reply.

That means eventhough I purchase the Furano Biei pass, I will still have to pay for some transport charges on Lavender Go Bus.

Since I am getting the Biei pass, therefore it is recommend that I should also visit Biei right?

I have to the the Furano lavender bus to my pension right?

Twinkle bus does not stop at all the stops right?

And the twinkle bus reservation, does it means that I have to book the seat in the main Furano station on the full route. That means if I alight at Cheese Factory and want to board back the Twinkle bus, I cannot just board the bus without the reservation.

Thanks
