MM Lee has claimed that no amount of Engineering could prevent floods.The Japanese has proven MM Lee WRONG.
The Japanese has started to build the G-Can, termed as "Underground Temple" to rid Tokyo of floods. This massive project which cost about S$4Billion was started in 1992 and completed in 2006. You can view more photos and read the introduction of G-Can here.
It has almost rid Tokyo of flooding due to typhoons and heavy rains. It is also believed that it could act as a massive underground bomb shelter.
You could read about the background information of this G-Can Underground Temple here.
Instead of letting GIC and Temasek Holdings losing billions of dollars in financial crisis, it will only cost us less than 10% of the total losses suffered by GIC and Temasek Holdings to engineer our way out of flooding. Tokyo is many times bigger than Singapore and I guess we should use less than the total amount of money needed for such project.
The following is a video in Japanese which show what will happen if such flood control measures like G-Can is not in place:

The video is part of a Japan government report warning that as many as 3,500 people could die in the event of such flooding. Water would also quickly flow into Tokyo’s subway network, putting as many as 97 stations out of commission.
