You already know the answer. Plant your seeds into the field if you know what I mean.

There's hotspring named Yunokawa-Onsen in Hakodate.
Where the hotspring comes out, it seems there are hotels or inns.

These hotels are members of Yunokawa Hotspring Association.
There are other hotels that don't join this association, but provide hotspring as well.

I've never stayed in these hotels, so I can't tell which one is good.
