Our group went on a field tour to a remain of a mine located in Hatanoshi Shibusawa in Kanagawa prefecture. In this mine, we were able to collect some sample ores of pyrite which are used in making crystal radios.

- After crossing the river, walk along the bank of the river until you reacha sign explaining about the remains of the mine.
- Destination reached.
The remains of the mine are located a little off the river, but by searching around the bank of the river, you will find a 2 meter sized rock. By examining the rock, you will find small octahedron sparkles. By hitting these sparkles with your sledge hammer it will spark and omit a sulfurous odour. From these facts we determined that these sparkles were pyrite.
