Welllll - it depends - they have lines of up to 2 hours waiting for taxis and buses to take people to work today in the Tokyo area. Farther south - Osaka, etc no such issues. Tokyo is still scheduling roling blackouts and a number or larger companies (Toyota for example) have closed for the day (I think mainly to prevent drains on the power grid). My own brother-in-law was stuck at work for a day and got home the next day after a long trip, but is not going in today (monday for them)......Just got word now of a new earthquake in Gunma prefecture of magnitude 3 so things still aren’t quiet
Nagano - magnitude 4.2
