Experience the Double Locks! Nov. 24


The water level of rivers and canals at east Tokyo low land is always kept 1m lower than that of the lowest tide level of Tokyo Bay and it has become possible by the locks.  Difference of water levels between the inside and outside of the lock is 3m at its maximum. 

How do boats come and go through two different water levels?

The best way to understand the mechanism is to get on a boat.  Here you can experience how two different water levels are adjusted in the lock chamber! 

In this excursion, we pass two locks, Ogibashi Lock and Arakawa Lock Gate.  East Tokyo low land is protected by these two locks.

After we come out from Arakawa Lock Gate, we cruise down Arakawa River's man-made part made during 1912 to 1930.  The river is so wide that we cannnot believe this is an artificial river.
