Kanazawa and Shirakawa-go bus questions

For bus travel from Kanazawa to Shirakawa-go and back, can someone that has taken this route/bus answer-

Do the buses have power outlets and wifi?
Are there bathrooms on board?
Can you bring a bento and drink on the way there?

I am considering taking the first bus of the day and reserve online.

You need 2620 yen,78 km by kaetsuno bus
From kanazawa eki nishiguchi to johana eki mae ,then ainokura, hatogaya, shirakawago

There are several bus companies which operate Kanazawa-Shirakawago line, and many booking sites which covers different bus, as far as I searched. My serach shows the eariest bus starts at 8:10 operated by Hokuriku Tetudou.

There seems to be USB outlet and free wifi, but Japanbusonline page shows no such facility. You should not expect onboard bathroom. It's 75 min ride so you might better use it at Kanazawa station (there should be clean bathrooms).

Reservation required.
