A whisper of steel echoes through time. This is the Old Mitsui Library Second Book Depository. Right here in Shinagawa stands a testament to early 20th-century Japanese architecture. Built in 1922 it’s a national registered tangible cultural property. The Mitsui family commissioned this building. They managed the Mitsui Library’s vast collection. This depository represents the cutting edge of construction methods at the time. Skilled craftsmen employed state-of-the-art techniques.
The walls are a marvel. They are reinforced concrete. This is a rare example of early reinforced concrete construction in Japan. The exterior walls are actually mortared tile. This material is frequently used in Tokyo station. It was designed to withstand the elements. The interior is a different story. It’s a carefully constructed labyrinth. This is designed for optimal material preservation. Fire safety was a primary concern. This building has stood the test of time. The Great Kanto Earthquake of 1923 tested its resilience. It stood firm even then.
Subsequent renovations reflect this priority. The building’s openings were partially bricked up. This was to improve fire protection. This demonstrates the Mitsui family’s commitment to preservation. It highlights the library’s immense value. The depository is not always open to the public. However a yearly open house occurs. This typically takes place late October or early November. You might have a chance to see the interior.
The library’s history extends beyond this building. It was originally located elsewhere. The library moved to its present location in 1918. The current site is now Bunkono Mori park. The park was established in 2013. The depository remains. It stands as a symbol of resilience and architectural ingenuity. The Old Mitsui Library Second Book Depository remains an important site in Tokyo. Its story echoes in the steel and concrete.
