Why was odaiba built?

Odaiba was built as part of Japan's urban development project in the late 1980s and early 1990s, aimed at revitalizing Tokyo Bay and creating a new commercial and entertainment hub. Initially developed as a fortified island for defense in the Edo period, it was transformed into a modern area featuring shopping centers, parks, and attractions to accommodate the growing population and stimulate tourism. The project also sought to enhance Tokyo's infrastructure and promote economic growth in the region. Today, Odaiba is a popular destination known for its futuristic architecture and recreational spaces.
