Ginzan Onsen Weekend Bus

I am looking if anyone could help me with the bus to Ginzan onsen from Oshida/Obanazawa.

I am having trouble telling if the bus runs an extra bus on weekends or if there is only one bus on the weekends.

The schedules are only available in japanese so I am a bit confused.

I would really apreciate if anyone familiar with this could clear it up for me.

Both of them are written in Japanese, but you can copy and paste them, so if you use a translation software such as Google Translate, you can read them in English.
There are 5 buses departing from Oishida station on weekends.
9:50, 12:35, 14:10, 15:55, 17:45
