The tunnel is about ten metres above the trail on a slope. The entrance is quite large and the first leg goes in about ten metres before turning right for two metres, then continuing on for another ten metres before turning left. It then terminates in a dead end.
This is one of the WWII Japanese tunnels in Bukit Timah Hill, Singapore. From this gated entrance you can see light far away from the other side, which might be another entrance of the tunnel. It is flooded, like the tunnel located north to it, or may be they are within the same tunnel system.
This is one of the WWII Japanese tunnels in Bukit Timah Hill, Singapore. It is flooded and gated. It extends several meters from the entrance, and seems to turn to other sides deep into the hill, like many tunnels in HK. South to it is another tunnel entrance. Not sure if they are connected somewhere inside.
This tunnel is the largest of the three I visited today. From video 2:03 you may find trenches, the long trenches are still easily recognizable, surrounding the hills, and the entrance of this tunnel is connected to this trench.
This is the shortest and smallest of the three tunnels on Chiu Keng Wan Shan. It is a dead end with a small room near the entrance, a stone bed is embedded in the room.
The video part for this tunnel starts at 0:30. Sorry for the camera issues you may have to rotate your necks (left 90 degrees) to view it comfortably.

I was doing a bit of unrelated research when I came across an interesting EIA report (https://www.epd.gov.hk/eia/register/report/eiareport/eia_1252006/html/e…). It seems that back in 2006 there was a plan to build a Liquid Natural Gas (LNG) receiving terminal at Black Point (https://goo.gl/maps/eTRsMMFojdxTUNu2A), though it appears to have been subsequently abandoned.
I did not know that there were WW2 tunnels in Lantau, but this looks like one. Relatively small with only one entrance L shaped. Next to Temple South crag with good command over the coastline below. The other option is that it is a mine prospect. No records of it in the maps checked, for example this one in the industrialhk web.
