Experience the Lock! 10/19, 11/2, and 11/3


Ogibashi Lock reopened since Aug. 1, 2019 after the reinforcement work

The water level of rivers and canals at east Tokyo low land is always kept 1m lower than that of the lowest tide of Tokyo Bay and it has become possble by the locks.  Differences of water levels between the inside and outside of the lock are 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 water levels are adjusted in the lock chamber!

Available only at Mizuha. Combo ticket with Tenugui cotton towel, Yen5,100

Kiyosu Bridge of 1928 is said to be the most graceful bridge among the bridges over Sumida River. This is our most favorite bridge and we put its shape into our logo mark. Nihonbashi's established shop Todaya, who handles a traditional stencil-dyed craft "tenugui" cotton towel, has a tenugui of Kiyosu Bridge. As this is going to discontinue, we asked them to keep its stencil to dye for us. We have started to offer combo ticket of Tokyo City of Water Cruise and Kiyosu Bridge tenugui for Yen5,100 (cruise ticket is Yen4,000). This is a special offer only available at Mizuha. Regular price of tenugui only is Yen1,620. Choose a combo ticket when you make a reservation. Will give you a tenugui when you get on board.


Attentive hospitality with style.
