Near the former junction of the TATEKAWA and YOKOKAWA rivers in mid century  stood a bell regularly rung to announce the hours for the Honjo  and  Fukagawa  neighborhoods .

 

Three nearby bridges are  KITATSUJI , MINAMITSUJI , and SHINTSUJI  were called  the  SHUMOKU bridges after the wooden hammer  ( Shumoku  )  used to strike the bell . 

They were dismantled in  1988 .
