Buses to Ginga Falls

Is there any buses that go to Ginga Falls? Where can I find more information (such as where to take the bus, schedule, etc)?

Thanks.

Thanks Cris, the link your provided is very useful. Just want to make sure my understanding is correct (figuring out the Japanese and English translation), am I right that there is a only one round trip bus daily from Sounkyo and back?

Can I alight at Takimidai and re-board at the same place after the bus has made its loop at Taiseitsuko and back? Or does the bus not pick up passengers on its way back to Sounkyo?

Is there a need to make reservation fr this bus?

Thanks.
