The Cocoon Tower, a distinctive skyscraper rising in the heart of Shinjuku, Tokyo, is one of the most recognizable buildings in the Japanese capital. Standing 204 meters tall, with its unique cocoon shape, the tower embodies the fusion of modern architecture and urban functionality. Primarily housing educational institutions, this structure is both an architectural marvel and a symbol of innovative design.
History and Construction of the Cocoon Tower
Officially known as the Mode Gakuen Cocoon Tower, the building was completed in 2008. Its name comes from Mode Gakuen, a specialized school focused on fashion, design, and information technology, which is the tower’s main occupant. Additionally, the HAL Tokyo creative technology school and the Shuto Ikō medical school also operate within the tower.

The architectural concept of the Cocoon Tower was designed by Tange Associates, a renowned Japanese architectural firm founded by Kenzo Tange, who played a key role in reshaping Japan’s urban landscape after World War II. The cocoon shape was chosen to symbolize “nurturing”, representing a space where students can grow and thrive. Unlike traditional rectangular or square skyscrapers, the Cocoon Tower stands out with its curved and twisted silhouette, wrapped in white bands resembling interwoven threads around a cocoon—hence its name.
This revolutionary design earned the Cocoon Tower several prestigious architectural awards, including the 2008 Skyscraper of the Year, placing it among the most innovative skyscrapers in the world. Beyond its exterior, the tower also boasts a forward-thinking interior layout, featuring open floors, integrated learning spaces, and communal areas that foster interaction between students and faculty.
A Tower Dedicated to Education
The Cocoon Tower primarily serves as an educational hub, accommodating over 10,000 students across its 50 floors. Unlike most traditional educational buildings, the tower combines classrooms with relaxation areas, libraries, and social spaces. The lack of dividing walls on certain floors encourages interdisciplinary collaboration and stimulates student creativity.
Impact on Shinjuku’s Urban Landscape
The Cocoon Tower has had a significant impact on Shinjuku’s urban development. Located in one of Tokyo’s most dynamic and densely populated districts, it stands out not only for its height but also for its landmark status. Its distinctive shape draws the attention of passersby and secures its place in Shinjuku’s skyline, alongside other iconic structures such as the Tokyo Metropolitan Government Building and the Park Hyatt Tokyo.

The tower is just a few minutes’ walk from Shinjuku Station, which is served by multiple train lines, including the JR Yamanote Line, Chuo Line, Sobu Line, Keio Line, and Odakyu Line. Shinjuku Station is not only one of Japan’s largest train stations but also one of the busiest in the world, making it a central access point for visitors and students alike.
