Entrance Hall and Grand Staircase, Akasaka Palace

Beyond the lofty ironwork door is the entrance hall, with black and white checkerboard floor overlaid with red carpet. The checkerboard, called the ichimatsu motif in Japan, is composed of black Japanese slate and white Italian marble. A similar floor can be seen in the Palace of Versailles in France.

Entrance Hall
The entrance hall. The floor has a black and white checkerboard pattern, and a red carpet has been laid in its middle, extending towards the central staircase.

The Entrance Hall is the area in which guests such as state and official guests visiting the State Guest House, Akasaka Palace first set foot. It is also where they first meet His Majesty the Emperor or the Prime Minister.

Guests enter the Main Building through these doors. Above the doors is the chrysanthemum crest of the Imperial Household. Upon entering the Entrance Hall, guests are greeted by a white wall that continues up to the ceiling.

Tōgo Murano , who oversaw the extensive renovation during the Shōwa period, strived to create this whiteness to balance the overall brightness of the building. Murano’s concept was to bring out the warmth of the pure white colour that reminds one of blend-looking official buildings by creating his own unique colour with the idea of “making white seem white, not making white look white.”

The floor is laid out in a chequered pattern using black and white marble. This was done by referencing the floor at Grand Trianon, a château (palace) of the Palace of Versailles. The marble stone was completely replaced during the major renovation in the Shōwa period.

Central Staircase
Stairs and halls full of various European marbles. The hall is decorated with paintings by Ryohei Koiso. Emperor and Empress welcome guests.

Large hall on the second floor
Guests ascend this staircase in the middle of the Main Building up to the second floor. The walls flanking the central staircase are covered in red marble stone.

It appears that red and green marble stones were used alternately to cover the walls when the building was first constructed, but the colour was unified during the extensive renovations in the Shōwa period to brighten up ambience of the entire building.

The Corinthian pilasters are made of stucco. This was to demonstrate technical sophistication when the building was first constructed.

Sunset is depicted to pair with the rising sun above the top landing of the staircase. The sunset sees off guests as they leave.

Akasaka Palace
The State Guest Houses (Akasaka Palace) are national facilities to receive foreign dignitaries, such as monarchs, presidents and prime ministers, from countries all over the world. The SGH plays one of the key roles of diplomacy through performing a wide variety of functions, including accommodating foreign dignitaries and holding summit meetings, signing ceremonies or banquets.

The State Guest House, Akasaka Palace serves as a splendid stage of diplomatic activities by welcoming monarchs and presidents from countries all over the world. The State Guest House, Akasaka Palace was the only palace in Japan that was built based on the neo-Baroque style as Crown Prince’s Palace in 1909. It is a structure built by mobilizing all available resources of the Japanese architectural, art and craft industries in those days and represents the culmination of Japan’s full-scale modern Western architecture in the Meiji period. Japan returned to the international community a dozen years after World War II and the number of foreign dignitaries that it welcomes increased; given this, the facilities were extensively restored and remodeled along with the construction of a new Japanese Style Annex and made a fresh start as the current State Guest Houses in 1974.

After the massive repair work in 2009, the State Guest Houses was designated as a national treasure as one of the structures that represent Japanese architecture. The State Guest Houses has received a large number of distinguished guests, such as monarchs, presidents or prime ministers, and been used as a venue for international conferences, including summit meetings, as well.
