On 9 March 1952, the National Historical Committee (precursor of NHCP), installed a commemorative plaque on Kudan which highlights the history of the building and its purchase by President Laurel in 1944.

[7] The unveiling of the marker happened on March 3, 2014, in the presence of Ambassador Lopez, NHCP chair Dr. Maria Serena Diokno, and Japanese and Filipino officials.

Located in the foyer are busts of Jose Rizal, Philippines' national hero and President Laurel.

Adjacent to the building is a garden where Princess Hitachi planted a sakura tree in 1994.
