I'm actually not that concerned about the Pacific operation, per se. Tokyo is a long way from Sendai. The bigger concern is the overall impact on the Japanese economy, depending on the severity of the incident. The US NRC is already voicing serious concerns about a "China Syndrome" type meltdown of the expended fuel depository. That may have long term implications for DAL, in particular. There is also the impact on the overall US economy if Japan heads south.

I'm not big fan of worrying about things you cannot control; it's pointless. It's really just a waiting game for now. Regardless, we still have Lagos.
