We searched for diffuse interstellar bands (DIBs) in the 0.91$<\lambda<$1.33 $\mu$m region by analyzing near-infrared (NIR) high-resolution ($R=20,000$ and 28,000) spectra of 31 reddened early-type stars ($0.04<E(B-V)<4.58$) an unreddened reference star. The were collected using WINERED spectrograph, which was mounted on 1.3 m Araki telescope at Koyama Astronomical Observatory, Japan, 2012--201...
