Mt Violet Japanese Tunnel [????- ]

As the Hiking and Tunnel finding season draws to a close, I went out last weekend for a poke around Mt Violet.

I came across a partially made tunnel and also a small tunnel. I started by heading up the path next to reservoir with the peddle boats, at the very top there is a slight dip before rising up again and joining onto the other path towards Parkview. At the bottom of the dip I noticed a small path leading around the side of the hill. I crashed through the bushes heading upwards and I found the partial tunnel. It looks like they started the entrance but didn't get to digging the actual tunnel. I continued up and eventually got to the very top ridge of Mt Violet with Deep water bay on my right and Repulse bay on the left. I followed the ridge along and noticed something about 10m down from the path. It was a small tunnel that only went in a couple of metres, turns 90 degrees left and then stops another couple of metre in. It was pretty tricky to spot as the entrance is slightly overgrown, but still easy to enter.
