The 27th Dec 2012 a Russian Air Force Il-20 flew over Sea Japan following the same route as the Tu-214 the 17th Dec 2012.
According the Japan web side:

There is a picture of plane on the web side. No usable signs of the aircraft sides.
Anyone good at Japanese?
Russia still use the Il-20, some of them are updated.
At least two of them are updated with outer signal areas as Tu-214. They are told to be used as flying "missiles".
Russians must be very interested of the sigint build up in area and the new world covered BMD defence.
