Politeness and scripts
Japanese has different politeness levels — casual, polite (-masu form), and honorific — and the right one depends on who you're speaking to. Machine translation usually defaults to polite, which is safe for most situations, but keep the context in mind for very formal or very casual messages.
Japanese uses three scripts (hiragana, katakana and kanji) mixed together; the translator handles this automatically, so you don't need to worry about it.
Getting accurate results
Japanese grammar and word order differ greatly from English, so short, clear sentences translate far more reliably than long, complex ones. Break long ideas into simple statements.
Avoid idioms and slang, and do a round-trip check (Japanese back to English) on important passages, since the structural differences make meaning easier to shift.
