This cache brought you to a geographically interesting spot
The cache is located on the river bank of Fudogawa River. Because the river flooded many time in the past, the river bed (and the river bank, too) has became much higher than the ground due to accumulation of sands carried by the river water. This type of river is called "Tenjo-gawa" which means "River flowing at a level higher than house ceilings".
Come to the coordinates, please look to the north. You will see the railroad track goes under the river. Yes, the trains are tunneling through under you!!. Have fun!
