Twinkle Bus Biei

Hi, need advice whether we can use Twinkle Bus Biei? it is quite confusing as from the brochure, it is stated that the bus is JR Users exclusive Bus (we have 7 days Japan Rail Pass) and that bus fare is necessary if you are a Japan Rail Pass or Hokkaido Rail Pass Holder but there is also a disclosure saying: only persons with a JR Hokkaido train ticket can use the bus.

Thank you.

Both Pass not covered that bus fare just booking possible
so you have to pay bus fare 1500Y/adult.

Booking until 2 days before at major JR Hokkaido stn ticket office.
But if not be full re-sale on the day

in 四季の情報館 building out of JR Biei stn.(1 min walk to left)

Thanks tllah. Am I right to say that as the holder of JRP, I can book the twinkle bus 2 days in advance and pay?

Basically "Yes" if be in Hokkaido until 2 days in advance.
(no online booking by web form/e-mail)
But if already booking full you have to change plan or wait cancel(s).
Seems bus seat numbers 2+2 type around 45 total.

JR Hokkaido ticket office list with open hours: (use google translate)

新千歳空港(Shin-Chitose) is "New Chitose" airport (CTS).
新 means "new" no different meanings but,
EN name using different reading. (very rare case)

Also if in out of Hokkaido(as in Japan "main land" or) until 5 days in advance
you can book by call to "ツインクルデスク/Twincle desk".
(JR Hokkaido's tellephone operator)

(No accept by int'l call "81+")

Thanks a lot tllah. This is indeed very helpfull. I assume the twinkle bus look like in the picture you send and it is the only bus? If not, I might not able to find it as the sign is in Japanese. How to say twinkle bus in japanese? If I were to ask people in the station?

Twinkle Bus is "ツインクルバス" same sound.
JR ticket office staff can speak EN well so no need speak Japanese for booking.
Airport(in/out CTS?) infomation desk staff,too no worry.
If still worried showing travel plan memo(handwriting)/web page printed/cellphone or PC screen/guide book/leaflet.

No need 号(gou) with.
This 号 means just numbering no important meanings.

But recommend study some basic letters/words/phrases.
