Kanazawa to Gokayama (advise on buses)

I am planning for a day trip from Kanazawa to Gokayama. From this web: https://gokayama-info.jp/en/access.php#kanazawa. I can do a bus trip of Kanazawa station Nishi-guchi No2 > Johana Station> Take the heritage bus > Ainokuraguchi bus stop> Suganuma bus stop.
May i ask where is Kanazawa station Nishi-guchi No2? It is next to JR Kanazawa?
From this web:
http://www.kaetsunou.co.jp/wordpress/wp-content/uploads/2020/03/nantok..., is Nishi-guchi No2 refer to 金沢駅西口 and i should alight at 城端 which is Suganuma?

By the way , as i am travelling in early Feb 2023, the buses route i mentioned above is still open ?

Thanks

The bus is running.

Buses marked in pink are out of service（Unkyu,運休）.
It also stops at the Ainokuraguchi（相倉口） bus stop on the way.

By the way, 2 is read as "ni" in Japanese.

Thanks for the inform- for both buses, am i allow to pre reserve? or it is base on availability of the seat when we board the bus?

It is written that reservations are not required for the World Heritage Bus.
You can also make a reservation in advance here.
However, since the website is only in Japanese, it may be difficult to make a reservation.

It looks like you can buy it from a machine at a convenience store, but it may be difficult because there is no information in English.

Reservations cannot be made for the Nanto-Kanazawa line. (From Kanazawa Station to Johana Station front)
There are also discounted tickets for the Nanto-Kanazawa line and discount passes for the Nanto-Kanazawa line and the World Heritage Bus.

If you plan to stay in Kanazawa before boarding the bus, I think it would be better to check with the tourist information center in Kanazawa.

hi, thanks for the infor above.

As i am staying at Kanazawa before my next day trip to Gokayama , Guess i could take a train to Shin-Takaoka Station(Gate 4) for the 8.25 am heritage bus .

From googling, there are 3 places to visit i.e Ainokuraguchi, Kaminashi and Suganuma, i can actually have lunch at Kaminashi where the Gokayam tourist Centre located. is this information correct>?

Also for lunch at Kaminashi, what is the budget i should cater for , for 3 person of a family?

Thanks : D
