Imperial Hotel light hall (帝国ホテルライト館) was built on September 1st 1923. It was designed by maestro Frank Floyd Wright who was so familiar with Japan as to own thousands of Ukiyoe. It is praised as a masterpiece in Japanese architecture.
1,500,000 yen was appropriated for construction but it ended up costing 9 million yen (presently 40 billion yen) over 4 years
The hotel gained publicity since it had withstood The Great Kanto Earthquake, which happened on opening day, without big damages.
It was used as an evacuation area for earthquake victims. The hotel made efforts to rebuild after the earthquake by providing food supplies, providing foreign embassies with special facilities as well as using its lobby for newspaper publishing companies.
