The central part of tokyo (ward 23) is (with a few very small exceptios) exempt from blackouts, due to having a lot of critical government infrastructure on its grid. Most central tokyo trains have multiple power sources, and are running all day with only slightly reduced schedules (they seem to be gradually ramping back up to full service; some, including the Yamanote line, are already back to the normal schedule). Trains to outlying areas often have to suspend service during blackout times, which rotate each day. Most Shinkansen lines are back up to some degree - some running full schedules - with the exception of lines heading northeast closer to the epicenter; those lines will need major track and station repair. A lot of people are staying home to help reduce load on the transportation and electrical infrastructure. Once the power plants start to come up (and people stop hoarding groceries), things should start to approach normality in the Tokyo area at least. Areas closer to the epicenter will need more rebuilding, however.
