Utility-scale solar is very unpopular in Japan. Because most suitable lands of them are densely forested, and installing utility-scale solar systems requires destory the forests.
There are concerns landslides due to reduced water storage functionality, and emotional antipathy at having their hometowns' mountains covered with solar panels.
(utility scale solar generators typically have a 35 year lifetime, so in areas of Japan where you’re not cutting down forests, it makes sense to build where depopulation is occurring in a “last person out shut off the light” sort of way before the rural community goes extinct)
