As the fellas have said, those characters are Chinese, not Japanese.
Those same Chinese characters, called
kanji in Japanese (
kan=Chinese +
ji=character), are also used in Japanese, however. Those two combinations have no meaning in Japanese, but as Reggie said, individually they can mean:
1.
Min, Tami: Humankind, people, citizens
2.
Tomo: Friends, companions
3.
Shin, Sara, Ara: New, fresh
4.
Mei, Min, Myou, Akari: Wisdom, brightness, brilliance (as in light), tomorrow, and is also the character for Ming, as in the Ming Dynasty.
5.
Sai: The state of someone or something being somewhere
6.
Tomo: Friends, companions (same as Kanji #2)
When used in combinations , called
jukugo, kanji can have different pronunciations. Which makes studying Japanese that much more fun!
I think
Sun Tze (or
Sun Tzu, or
Sun Zi) is only two characters, by the way.
