Rule for Living in Japan No. 509 (no, I’m not keeping track, but I should start):
Never sign your name sloppily. While this is perfectly acceptable in the U.S. and may even help to prevent signature forgery, here it will cause the insurance company or whomever to come back to your house after you have gotten in the shower to ask you to re-sign, then display great shock and awe at the fact that, yes, you can write your OWN NAME in a legible and even neat manner (after having refused the suggested practice runs, at that) while dripping wet and not wearing a bra.
