Discrimination and abuse still occur on Earth's surface world. It is practiced not only in developing countries but also in developed countries. For example, in Japan, the weak are oppressed by some powerful people. Although it is called a developed country, many workers earn only the minimum wage per month, and it is extremely difficult to change jobs from there to jobs that increase income. Moreover, only a few economic winners receive all the benefits of society, while many people are unable to break out of the lower class. Moreover, the victors hoard the benefits for themselves and their allies, turning a blind eye to or ignoring the poverty of the weak. I feel that on such a beautiful earth, the ugly and horrible aspects of humankind are increasing day by day. I was saddened by this current situation and wrote the lyrics for this "Lament for the Oppressed on Earth". I pray that true peace will come to this earth.
