Throwing catiuscos in Tokyo subway

In case of no solution, floods can occur in the Tokyo metro shortly. The railway and station network has been expanded to underground since the 1960s, too close to groundwater. Now, engineers fear that pressure will affect the structures of some stations. If the water level rises another 70 cm, they will have big problems in Tokyo. Given its structure, the adaptation of the metro network to the new situation is very complex, so engineers have crossed their fingers so that the water level remains as it has done in the last 3 years.
