  NEWAGE is a direction-sensitive dark matter search experiment with a
three-dimensional tracking detector based on a gaseous micro time projection
chamber. A direction-sensitive dark matter search was carried out at Kamioka
Observatory with a total live time of 318.0 days resulting in an exposure of
3.18 kg$\cdot$days. A new gamma-ray rejection and a head-tail determination
analysis were implemented for this work. No significant non-isotropic signal
from the directional analysis was found and a 90% confidence level upper limit
on spin-dependent WIMP-proton cross section of 25.7 pb for WIMP mass of 150
GeV/c2 was derived. This upper limit is the most stringent in the
direction-sensitive dark matter searches.
