I was approached by my colleague today asking me to sign a baby shower card. I was puzzled; I had no idea what to write! Taking into a consideration that this card was meant for someone who came from a different culture, Japanese. Are there some general wishes I could learn for the future use, so I won't offend anyone?

tnx!

In my opinion, no matter what culture you are writing the card for, kind words always translate well. I stick to the "Health Wealth and Happiness" wishes, works all the time, but can get a bit boring if multiple people have posted the same thing on the card already.
