Theme: Creating a vibrant and lively waterfront space

Tokyo’s rivers used to be far removed from people’s lives due to factors such as concrete levees separating the river from the city and the deterioration of water quality. However, in recent years, the construction of super levees and riverside terraces has improved hydrophilicity and water quality, leading to increased utilization of river spaces.
This symposium will use the latest knowledge to consider “creating vibrant waterfront spaces,” and will also learn about measures necessary to protect lives from flooding when utilizing river spaces.

Keynote Speech

Takeyoshi Chibana (Professor, National Graduate Institute for Policy Studies)
Member of the “Committee for the Study of Waterfront Development for the Future of Tokyo”

Mr. Takeyoshi Chibana

“Know the river, be interested in the river, see the river, and get involved with the river.”

I assume that anyone reading this has some interest in rivers. Some are interested in river creatures, water quality, history, and scenery, some are afraid of floods, and some want to do something related to rivers.
If you gain new knowledge about rivers, it may spark new interest, and with even more new knowledge, your perspective on rivers may change. I only know a small part of rivers, but I hope to share as many different perspectives on rivers as possible, and to inspire everyone to want to get involved with rivers.

Special lecture

Miki Katayama (weather forecaster and disaster prevention specialist)
Currently appearing on NHK General TV’s “Metropolitan Network,” “Weather Information 1154,” and “Weather Information 1853”

Ms. Miki Katayama

“How to safely interact with rivers and protect lives from increasing weather disasters”

Tokyo’s rivers create beautiful scenery. They are essential places for us to relax, but the situation can change dramatically in the event of a disaster. In recent years, record-breaking heavy rains have become more frequent due to the effects of global warming, and the risk of river flooding cannot be ignored. Summer is a season when waterside accidents increase in particular. What measures are necessary to protect lives from flooding? Why not learn about disaster prevention weather information that can be used to protect lives from disasters and preparations that individuals can make, and reconsider how you interact with our beautiful rivers?
