18-Apr-2007 -- I could find the road to the monument park, named YUMERIA-34, which was at N34 E134 based on Tokyo datum.
I parked the car at the parking lot of the park.
I checked the monument position, it was located at N34.00.14.1 E188.8.131.52 WGS84.
According to my map, there was a trail to the south of the park, and it would guide me to the closer point to the target.
I went into the forest to the south side of the park, and after 30 meters walk, I found the small footpath.
What I did was follow the path about 400 meters, and I was at only 60 meters west of the target. It was east to walk in the forest.
It took only 20 minutes to reach the target after starting.
When returning to the park, I found that the path was connected to the south-west corner of the monument park area.
