The SuperKEKB project is in progress toward the initial physics run in autumn 2018. It assumes the nano-beam scheme, in which the emittance of the colliding beams is 4.6 nm. To achieve such a low emittance, it is vitally important to preserve the emittance during the transport of the beam from the linac to the main ring. One of the most difficult sections is the injection system. Since the dynamic aperture is small for the low emittance, the allowed distances between the stored beam and the injected beam at the injection point are 7.8 mm for the betatron injection and 7.2 mm for the synchrotron injection. The new septum magnets has been constructed and installed in the beam line after the measurement of magnetic flux density and aging test. It has been also checked the septum magnets are capable of design orbit. The initial beam injection succeeded on schedule and they had been operated without any big troubles in the first beam run of Phase-1.
