NEWAGE is a direction-sensitive direct dark matter search experiment. NEWAGE uses a micro time-projection chamber with a detection volume of $\rm 31 \times 31 \times 41 cm^3$, which is read by a macro-petterned gaseous detectors, $\rm \mu$-PIC. Underground measurements with the current detector, NEWAGE-0.3b’, have been performed since 2013. After the first direction-sensitive limits drived from 31.6 live-days of NEWAGE-0.3b' data were published, measurements were continued and the preliminary results from an addtional 170 days of results are reported here. In order to improve the sensitivity, low $\alpha$-particle emission $\rm \mu-PICs$ are being developed. Studies on negative-ion gases are also on-going. These recent activities that aim to improve the sensitivity are also presented here.
