Is intake into that discharge channel controlled?

Flash flooding is a thing. In Hong Kong, the Drainage Services Department puts up warnings and runs TV ads to tell people to stay clear of discharge channels, lest they get swept away by flash flooding during heavy rains.

So if intake into the discharge channel is not controlled, isn't it kinda dangerous to film there?

The "temple" where filming is done is a secondary reservoir, it only receives water after the primary detention silos are full. So there is plenty of warning.

It's amazing just how much stuff there is under Tokyo - not just infrastructure like this and the usual transport links but entire multi-storey shopping malls. There's almost a whole city beneath the city. It's possible to travel for miles without ever seeing daylight!

Tokyo was a city of canals before the Allies firebombed the city. Apparently the canals boiled due to the incendiaries used, so there was no escape from the fire during that tragic phase of life in the city. 100,000 deaths in one night is a statistic that few people think about, the Nazi death camps worked at a glacial pace in comparison, the craziness of WW1 campaigns gains a new perspective too, the bombing of Tokyo, with the loss of those canals, was something else. Hard to imagine. So we don't talk about it.

Tokyo was built on an estuary so the canals came from the management of the water that was already there. The final evolution being the water being pushed completely underground is pretty predictable. Other cities have dealt a similar fate to their rivers, London being a prime example where only the Thames is really 'welcomed' as a river, everything else is kind of banished underground.
