Theme: Waterfront Improvement for the Future Tokyo

 In the past, the Sumida River and other rivers were the center of culture, economy, and daily life. Even today, the waterfront is being utilized in a variety of ways, with open-air cafes along the river bustling with activity and marche markets being held in various locations. Meanwhile, as lifestyles and work styles change, the importance of open space in public spaces, including waterfront areas, is growing in terms of its ability to provide “comfort and enrichment. In this symposium, we will consider how the future of Tokyo’s waterfront should be envisioned, and what kind of future the great figures of the past envisioned and entrusted to us.

Lecture theme: “Toward the New Tokyo Waterfront 100 Views” Development and utilization of waterfront for the future TOKYO

 The Tokyo Metropolitan Government has launched a study group on “Waterfront Improvement for the Future Tokyo” in 2022, and has repeatedly discussed the future of Tokyo’s urban development and rivers.
 Based on the report compiled this time, we would like to discuss with you how the waterfront should be developed and utilized for the future Tokyo.
 More than 160 years have passed since Hiroshige Utagawa painted “Meisho Edo hyakkei (One hundred Famous Views of Edo),” so let us once again focus on the waterfront and consider the 100 new Tokyo waterfront views.

Special Lecture

Speaker: Mr. Tetsuo OWADA

 Professor Emeritus, Shizuoka University
 President of the Japan Castle Foundation
 Director, Sekigahara Battlefield Memorial Museum, Gifu

The historical archaeologist of the historical drama “What to do about Ieyasu” will give a thorough explanation of the urban development of Edo!

Lecture Theme: Tokugawa Ieyasu’s Edo Remodeling Plan and Rivers

 In 1590, Tokugawa Ieyasu was ordered by Toyotomi Hideyoshi to relocate the Hojo clan’s estate to the Kanto region. The castle was moved from Sunpu to Edo, but until then Edo had not developed as a castle town, although there was a branch castle of Odawara Castle, Edo Castle. It was a marshy area with several rivers flowing through it. Therefore, Ieyasu began to build a new town along with the construction of the castle. This section follows how Ieyasu changed the flow of the river and developed the town of Edo.
