In late 2006, all three sets underwent modifications at JR East's Kōriyama Works to reinforce the front end snowploughs and add protection plates to underfloor equipment.
From the start of 4 December 2010 timetable revision, the E751 series sets were replaced on ''Tsugaru'' services by 4-car
485-3000 series EMUs,
and were temporarily removed from regular service. From 23 April 2011, the fleet of three E751 series sets were reinstated on ''Tsugaru'' services, this time formed as 4-car sets, replacing the 485-3000 series sets.
The three pairs of MoHa E751 and MoHa E750 cars removed were stored at Aomori Depot, and occasionally reinserted into sets to provide increased capacity during busy seasons
until the three pairs of cars were withdrawn in 2015.
