It’s all in Japanese, but if you’re curious about the characters used to write Minmei, look at the first two from the big picture at the top.
The company was named after a legendary Chinese martial artist by the name of Zhou Min Ming. Minmei is the Japanese pronounciation of the name Min Ming.
As it turns out, it looks like Min Ming, with the exact same characters as above, is used as a female name in China. The characters mean “people” (as in People’s Republic of China) and “bright”.
But then, maybe the company you’re talking about isn’t Minmei publishing. In which case forget all of the above.
