Here's an update on something I posted earlier:

--- start quote ---
Japanese Customs officials may have been especially suspicious because the 180 pills were not in their original prescription bottle. Inspectors found the unmarked container in a box of household supplies that Carrie Russell sent to herself in Nagoya in preparation for starting an English-teaching job there.
Jill Russell said she had repackaged the Adderall to protect against theft and to guard her daughter's privacy in Japan, where mental health conditions can be stigmatized.

To say the least, this "protection of privacy" strategy backfired.

Again, this is not an issue unique to Kumamoto but of general interest to people who travel internationally.
