I walked around along the Kanda river

The Kanda river is one of the favorite river in Tokyo.

Its flow path have been changed for about 400 years.

Tokyo's history it is no exaggeration to say that 

the history of the flood control of the Kanda River.

I tried to walk along the Kanda river as the first

step to learn of the flood control in Tokyo.

The typical view of The Kanda river.
It's hardened by concrete and dug deeply.
It prevent the river from overflowing. 

The river partly flows under the high way.

There are beautiful flowers beside it.

The water quality appears to be good.
In fact, I can find some carps in it.
