Dear Mike,
Thank you for your kind offer. Two friends are staying with the family members that they were visiting this week in Tokyo and my lovely wife's son and his family are staying with in-laws near Haneda.
Be well, careful and safe. The idea to store some extra water as mentioned above was well thought through.
Respectfully,
Robert
Edit: Family members flew out of Haneda and will land shortly and be home later this evening. And Mike, please keep one sharp eye on that reactor and trust your instincts.
