Japanese Tunnel above Shau Kei Wan [????- ] | Gwulo: Old Hong Kong

Japanese Tunnel above Shau Kei Wan [????- ]

Current condition: 
Unknown

The "Hiking Trail HK" App (avail on Android) shows a Japanese Tunnel here.

I have passed by recently but couldn't see anything.

Can anyone verify this place or has more information?

There's nothing shown at the spot on that App, perhaps they have removed it, so you may also remove this spot accordingly.

I looked up the 1963 Aerial of the area and there seems to be something. Right in the middle of that Horseshoe shaped flat trail in that area. 

There's no trace of junction at the level walk, maybe no path leading to the cave anymore, perhaps you have to check it out on your own before the rainy season comes.
