A city has no electricity of its own: the sites in Iwamizawa are connected to the national grid, itself interconnected with its neighbours. What is measured, and what decides, is therefore the country's generation mix. No single source dominates it: the largest, natural gas, supplies only 32.8% (2025). The detail: natural gas 32.8%, coal 32.1%, solar 9.8%, nuclear 9.1%, hydro 7.2%, bioenergy 5.3%. Fossil fuels (coal, gas, oil) account for 67.4% of it. A kilowatt-hour there weighs 477 g of CO2, i.e. about the world average (458 g), 2025 figure. Concretely: a 3 kVA rack, in a site with a PUE of 1.5, draws 35,478 kWh a year and therefore emits 16.9 tonnes of CO2 a year here. The same rack, same hardware, same PUE, would emit 16 tonnes on a world-average grid. The building has nothing to do with it: the country does.

Since 1970, 34 earthquakes of magnitude 5 or above have been recorded within 100 km of Iwamizawa, and 309 within 200 km. The strongest: magnitude 7.6 in 1993, 157 km away. This record covers 56 years, which is short on a seismic timescale: no recorded earthquake does not mean no hazard. It does not replace the statutory zoning, which alone binds construction.

With a single listed site, Iwamizawa cannot support a disaster-recovery plan spread over two separate buildings within the same town. A second site remains necessary, and it is found in the nearby cities listed below. No Internet exchange point is listed here: traffic will run over transit bought from a carrier, which is billed by bandwidth. No rate is published by the operators in this city: pricing is on request, and we do not estimate it on their behalf.
The nearest site outside Iwamizawa is 34 km away, in Sapporo-shi. Short distances matter: they drive the cost of a link between two buildings, and whether a backup site is workable.
