It’s a fairly common sight in Joetsu, particularly for government buildings. This company shows a list of seismic retrofitting projects that it has done in Joetsu, for example:

There are also subsidies and financing available in Niigata prefecture for seismic retrofitting wooden homes built before 1981:

For sure though there are many homes in the area that have never been retrofitted.
