japanese keyword - low CPC and competition

hey folks

totally new to SEO, so apologies in advance if this is a dumb question

so i've stumbled upon some japanese keywords - more than 50k search volume with commercial intent

the CPC is $0.9 and the competitive density is 0.05 -- does this mean, it would be easy to run conversion ads that perform well? these words also have commercial intent

is this too good to be true or is this something common you encounter these days?
