Energy-resolved neutron transmission imaging technique using an accelerator-driven pulsed neutron source and a time-resolved two-dimensional detector can obtain the Bragg-edge transmission spectrum at each pixel. In this technique, crystallographic information can be visualized over a wide area of a sample. We used this method to investigate the crystallographic information of a modern Japanese sword produced by Masamitsu in 1969. As a result, shifting and broadening of the (110) Bragg-edge was confirmed at the cutting-edge side. It is evidence that the martensite phase exists at the cutting-edge side as a result of the quenching process. By comparing with results of the old Japanese swords, it is found that the martensite region in the modern Japanese sword is wider or deeper than one in the old swords. In addition, we can see strongly preferred orientation of the crystal grains at the boundary between the martensite phase on the cutting-edge side and the ferrite phase on the back-edge side.
