The 3-D spiral injection scheme is a brand-new idea and currently under development at KEK Tsukuba campus as a one of important test experiments of the muon g-2/EDM experiment at J-PARC. Establishment and demonstration of feasibility will be a significant achievement in accelerator technology. The test experiment is utilizing 116keV DC electron gun and 100 Gauss solenoidal magnet for the storage of electron beam in 0.115m radius orbit. We have performed the simulation of the storage solenoidal magnet in OPERA and CST-EM, the field measurement results are in acceptable agreement with experimental values. Fluorescence screen monitors are used to perceive electron beam. We have successfully transported DC electron beam from a gun to one step behind from the storage chamber through a dipole magnet. We are now under trial operation for a stable storage. We will also present a visible-light 3-D trajectory by ionized nitrogen gas in the storage chamber. Future prospects towards the g-2/EDM experiment at J-PARC are also discussed.
