Furano / Moderate shaking (MMI V) : Light shaking, followed by a pause then shaking progressively increasing in intensity to moderate. Then rolling motion after another pause.  
Kiroro / Light shaking (MMI IV) : It woke us up from sleeping. Things were ratlling and the bed was shakin For some reason I think I woke a few minutes earlier too so something may have caused that.   
Sapporo / Moderate shaking (MMI V) : Alarm went off on mobile phones, gave us about 5 sec warning which was good. Positioned ourselves safely and immediately building started shaking moderately strongly but not violently.   
Tokyo / Weak shaking (MMI III)
Ota (Japan, 860 km S of epicenter) : The swaying continued for about 1.5minutes (reported through EMSC)  
Muroran (Japan, 196 km W of epicenter) : Das Alarmsystem des Hauses wurde ausgelöst, zumindest die Feuerschutztüren geschlossen. Das ist vorher noch nie aufgetreten. (reported through EMSC)
