The trains were built by Kawasaki Heavy Industries, with exterior and interior styling overseen by Japanese industrial designer Ken Okuyama.[1] The driving cabs at each end of the three-car trainsets includes an automatically extending gangway connection to allow trains to be coupled or split en route.[1]

The trains have active suspension, a first for trains operated by Tobu, and use permanent-magnet synchronous motor (PMSM) traction motors.[1]
