Salmon stocks in the Shinano gawa (in the north of the island) dwindled. Investigations revealed that East Japan Railway (JR East) had been fiddling the meters
JR(East) had a permit to extract up to 317 tonnes of water per second from the Miyanaka dam for its hydro electric plant
The gauges were set never to read more than 317. The salmon were left with not enough water to swim in
The Japanese government have revoked JR’s permit
If an alternative source of 450 MW cannot be found, Japan’s legendary trains will no longer run on time
