In Japan, the traditionally does not refer to a single location, but to any residence of the imperial crown prince. As Prince Akishino, the current heir presumptive, is not a direct male descendant of the Emperor and not an imperial crown prince himself, there is currently no Tà Âgà « Palace in Japan and there will not be one until there is another imperial crown prince.
The palace where then-crown Prince Naruhito resided before his ascension to the Chrysantheum throne on 1 May 2019 was called Tà Âgà « Palace, but changed its name to when Naruhito became emperor. The Emperor used this palace as his primary residence until he moved to the Fukiage Palace of the Imperial Palace in September 2021.
Similarly, Akihito lived in this same palace when Hirohito died. Between his accession to the throne in 1989 and his moving to the Fukiage Palace in December 1993 the palace was also called Akasaka Palace.
The Akasaka Palace is located in the Akasaka Estate in Moto-Akasaka and is not accessible to the public.

After her death at the palace in 1951, the site was converted to the crown prince's residence. A reinforced-concrete building, designed by Yoshirà  Taniguchi was achieved in 1960. It saw the first wave of expansion works in 1978. A Japanese Garden was added in 1994 for the arrival of the crown princess Masako. Additional renewal works took place in 1997 (installation of an elevator for wheelchair users, barrier-free design, seismic reinforcement). Works for a kid's area took place in 2001 as Masako was pregnant.
A major series of renewal works took place for a year in 2008âÂÂ2009, during which time the Prince lived temporarily in the smaller of the estate, which was renamed for the occasion . Some solar panels were installed on the roof, as well as LED lighting.
The palace has 72 rooms (12 reception rooms, 38 office rooms, 22 residence rooms). It has two floors and one basement floor.
In the Heian Palace, the Tà Âgà « palace was located on the eastern side of the , the inner palace. Towards the beginning of the 10th century, the , located inside the Dairi, came to be generally used as the Tà Âgà « palace.
Asahito became Imperial crown Prince in 1683 and from 1686 used a different palace than the Imperial palace for his Tà Âgà « palace, located where the Kyà Âto Sentà  palace is.
After that, the , located inside the Kyà Âto Imperial Palace itself, was used as the Tà Âgà « palace.
The construction of a Tà Âgà « palace for Yoshihito (future emperor Taisho) began in 1899, and was achieved in 1909. The building is now the Geihinkan.
The Takanawa Residence was used as the Tà Âgà « palace for the early years of Hirohito, future emperor Shà Âwa. After his wedding, he moved to (then named) Akasaka Palace (current Geihinkan).
