A quick primer on ways to say Black Lives Matter in Japanese.

[Kokujin no inochi wa taisetu] – Black Lives Matter (are important with no implied too)

[Kokujin no inochi koso taisetu] – It is Black Lives that Matter, Black Lives Matter! (Indeed!), more so than others

[Kokujin no inochi mo taisetu] – Black Lives Matter (too), closest to English in implication, and nuance

Note: I am an advanced speaker, but Japanese is not my first language. Constructive feedback welcome.
