The government is planning to expand citizens' "right to enjoy sunlight." The Environment Ministry will push for revisions to the environmental dispute settlement law, which will allow people to apply for government mediation in disputes over the issue. Currently, the Construction Law requires a certain distance between buildings so as not to block the sunlight, which is viewed as vital to physical and mental health. But the law doesn't guarantee the right to sunlight in cases involving overpasses, elevated roads and railroads.
