Immediately following the 11th March 2011 Mw 9.0 Tohoku (Japan) earthquake, a field investigation was carried out around the Tokyo Bay area. This paper provides first-hand observations (before or just at the onset of repair)of widespread liquefaction and the associated effects. Observations related to uplift of manholes, settlement of ground, performance of building sand bridges and the effects of ground improvements are also presented. Recorded ground motions near the Tokyo Bay area were analysed to understand their key characteristics(large amplitude and long duration). Lessons learnt are also presented.
