Ryouan-ji卫星地图 (日本大阪城市指南)
Its name is also commonly spelled 'Ryoan-ji' to lessen the vowels, although this removes the indicator that the 'o' is to be longer in length than one normally intones.
This temple is a popular place to visit and is known for its zen rock and sand garden. I believe the marker is on the garden in question.
