Checking in hard.
Specialized private marriage investigators in Japan confirm that bride and groom are completely free of yakuza affiliation before anything is signed. Nobody thought to mention any of this as I grew up in rural Connecticut, so my wife is mobbed up. Two of her uncles are heavy in the Sumiyoshi-kai, the second largest yakuza clan and chunky shareholders of Hawaii, which they use as a mid-station between Japan and the American mainland. So my wife can have me killed really easily. I live in fear.
