Tomari nuclear power plant in context
The nearest other tracked nuclear sites are Ohma nuclear power plant (173 km).
Nearest tracked nuclear sites

How these are worked out: ranks use gross operating capacity; ages count from the start-up year on record, as on the age page; build times run from construction start to grid connection, as on the build-times page; ratings are the tracker's net and design net capacity, as on the uprates page. Distances are straight-line between exact positions, so a site with only an approximate position gets none. A unit missing a date or a rating is left out of the figure that needs it.
| Location | Hokkaido, Japan |
|---|---|
| Coordinates | 43.0367, 140.5125 |
| Elevation | about 20 mabove sea level |
| Setting | On the sea coast, 0.1 km from the water |
| Region | Eastern Asia |
| Units by status | Mothballed: 3 |
Elevation is read at the listed coordinates from a 30 m terrain model (SRTM 30 m). Two independent models differ by a median of 6 m across our plants and by up to about 40 m on steep or coastal ground, and a point on a shoreline can read as sea level. Distance to the water is measured to a generalised 1:10 million coastline, so a few kilometres or less is not resolved. This is context, not a design-basis or flood-risk figure.
