My daughter's high school japanese doesn't really help, but she tried.
The top two characters are complicated words - you'd need a suitable dictionary.
The bottom characters are four basic characters which my daughter says are usually an attempt to sound out an English word - but we cannot make sense of it. They are "She Su Teh Moo" in a phonetic sense. Doesn't sound like an obvious word to us - eg. not "check"??
Sorry, not much use.
