Factual error: It's established that the victim disappeared on June 10th 1987 which was the day the time capsule was sealed. However, earlier in the episode the tank is being drained and a part of the album Appetite for Destruction by the band Guns N' Roses is in the capsule. The album was initially released on July 21st 1987. Further to this, the sleeve of the album shows the common 'Cross' artwork which wasn't used on the 1st press of the album. The 'Cross' artwork was first released later that year. (00:12:00)
Answer: Since the palatine bone is a bone that helps form the mouth it has a lot to do with speaking. The shape of it differs a lot depending on your ethnic background. I would guess that they, in the show, meant that the person's bone tells that they were Japanese and that it was "made for the purpose of speaking Japanese." That's what I'd assume anyway. I've studied molecular biology though, so I'm not an expert on bones.
