Hmm, I hope this helps even from my lack of great landscaping/designing skills!
I would probably try in the middle, surrounded by bamboos that way it can be one of the public work projects that's the center of attention. I would avoid puting them too close to any buildings, ponds or houses ect, because it might look a bit crowded or too much.. I noticed that maybe making a walk way with the bamboos to the hotspring along either the left side or right side of the walls to make it feel and look more in the game and decorative I suppose! But yeah, if there's a mistake i'm sure you can rebuild it in another area
