The SMS cell broadcast feature is kind of flaky. Nothing wrong with the technology, but it needs to be enabled in so many places to get through it rarely happens. Also consider that Japan never really did the whole GSM thing, so it's easy to imagine they haven't bothered with all legacy features still present in UMTS.

Not to mention that Japan uses different W-CDMA channels than many other places in the world, so if the people you know have foreign phones they may get limited CB coverage.

That's not it since the ETWS works fine normally, plus there's a strong correlation of people being north of Tokyo and receiving the alerts. kalleboo found an article listing the prefectures that received the alert and Tokyo is indeed excluded from it.
