Imperial Household Agency in the context of Board of Ceremonies

Chiyoda (千代田, Chiyoda) is a district of Chiyoda, Tokyo, Japan. In Japanese it translates as a "field of a thousand generations"

Chiyoda covers the grounds of the Imperial Palace, and nothing else. It does not have any subdivisions, and no chome or postal code designation. The address of the palace itself and of the Imperial Household Agency is Chiyoda 1-1, the address of the Hospital of the Imperial Household is Chiyoda 1-2, the Imperial Guard Headquarters is Chiyoda 1-3.

The Kyōto Imperial Palace (京都御所, Kyōto-gosho), also known as Dairi (内裏), is the former palace of the Emperor of Japan from 1337 to 1869 located in Kamigyō-ku, Kyoto, Japan. Since the Meiji Restoration in 1869, the Emperors have resided at the Tokyo Imperial Palace, while the preservation of the Kyoto Imperial Palace was ordered in 1877. Today, the grounds are open to the public, and the Imperial Household Agency hosts public tours of the buildings several times a day.

The Kyoto Imperial Palace is the latest of the imperial palaces built in the northeastern part of the old capital of Heian-kyō (now known as Kyoto) after the abandonment of the Heian Palace that was located to the west of the current palace during the Heian period. The Palace lost much of its function at the time of the Meiji Restoration, when the capital functions were moved to Tokyo in 1869. However, Emperor Taishō and Shōwa still had their enthronement ceremonies at the palace.

The Mozu Tombs (百舌鳥古墳群, Mozu kofungun) are a group of kofun (Japanese: 古墳)—megalithic tombs—in Sakai, Osaka Prefecture, Japan. Originally consisting of more than 100 tombs, fewer than 50% of the key-hole, round, and rectangular tombs remain.

The Daisenryo Kofun (大仙陵古墳, Daisenryō kofun), the largest kofun in Japan, is believed to have been constructed over a period of 20 years in the mid 5th century during the Kofun Period. While it cannot be accurately confirmed, it is commonly accepted that the tomb was built for the late Emperor Nintoku. The Imperial Household Agency of Japan treats it as such.

The Ministry of the Imperial Household (宮内省, Kunai-shō) was a division of the eighth century Japanese government of the Imperial Court in Kyoto, instituted in the Asuka period and formalized during the Heian period. The Ministry was reorganized in the Meiji period and existed until 1947, before being replaced by the Imperial Household Agency.

Maruyama Kofun (丸山古墳) is a Kofun period burial mound, located in the Mise-chō, Gojōnō-chō, and Oikaru-chōo neighborhoods of the city of Kashihara, Nara in the Kansai region of Japan. The tumulus was designated a National Historic Site of Japan in 1969 with the area under protection expanded in 1983; however, the posterior circular portion of the tumulus is under the direct control of the Imperial Household Agency as a possible imperial tomb. The tumulus is also called the Gojōnō Maruyama Kofun (五条野丸山古墳), Oikaru Maruyama Kofun (大軽丸山古墳), or the Mise Maruyama Kofun (見瀬丸山古墳). It is the largest kofun in Nara Prefecture and the 6th largest in the country.

Katayama Tōkuma (片山 東熊; 18 January 1854 – 24 October 1917) was a Japanese architect who designed the original buildings for the Imperial Nara Museum as well as the Kyoto Imperial Museum and was significant in introducing Western, particularly French architecture into Japan.

Coming from Chōshū, Tōkuma was a protégé of Yamagata Aritomo. In 1879 he graduated from the Imperial College of Engineering. During his late twenties and early thirties he assisted Josiah Conder in designing and building a Western-style residence for Prince Arisugawa Taruhito and then on the new Imperial Palace in Tokyo. During the 1880 he was sent to Europe and America to study interior decoration, including furniture. In 1887 he was appointed as an officer in the construction office of the Imperial Household.
