It's a little hard to find. If you come from Gora by bus get off at the Senkyoromae stop. Look back in the direction you came and you'll see a sign for Nakamura wriiten in hiragana なかむらwith an arrow directing you around the corner and up the hill. After going what feels to be 300 metres up the hill you'll find it on the right, tucked away in the greenery. It's well worth the hike.
