Why not leave Yomiyama? In the anime Another, the town of Yomiyama is cursed with a calamity that causes the deaths of members of Class 3-3 and their family members living in the town.

This is obviously a big problem. So why don't the members of 3-3 and their families switch schools? Wouldn't that be a better choice than to risk death in Yomiyama?
The deaths are tied to both members of class 3-3 and Yomiyama. My guess is that if you try to leave either class 3-3 or Yomiyama you'll be killed by doing so, rather than waiting for your turn to die through the normal means of the curse--one death every month.

This is mentioned in the show due to one of the character's deaths and on the wiki:


   Aya Ayano - While leaving Yomiyama with her parents in their family car, a rock fell and hit the windshield, causing her father to lose control and drive off the mountain.
