Asian songs with a message? (Environmental, protest, etc.)

[Taishaku]

Hey guys, I was asking myself the other day, are there any songs made by Japanese or Asian artists that treat issues like the environment or things like that? For example, in Latin America it's pretty easy to find artists that have done protest/political songs in their careers (like Shakira's "Octavo Día" or "Latinoamérica" by Calle 13).

There's a song by OLIVIA called "Celestial Delinquent" that is very pro-Earth and anti-capitalism, but it's in English, so I don't know if it counts.

Hope you can help me with this!

PS.: "everywhere nowhere" by Ayu would be a good example, since it criticizes the over-flooding of products and information, which makes us think we're "free", but also slaves of consumerism at the same time.
