Kashiwazaki Location

37.3719, 138.5590

37.37192, 138.55901 View on OpenStreetMap →

Kashiwazaki sits at 37.3719°N, 138.5590°E, on the coast of Japan. The marker on the map shows the spot the readings on this page come from. It usually sits a short distance from the town centre, out on the open water itself, so the numbers stay tied to the coast rather than a generic point inland.

Coastlines bend, headlands focus the water, and the temperature can run noticeably differently between two beaches that look close together on a map. Comparing nearby locations is a quick way to see how local geography is shaping the readings.
