After Toyotomi Hideyoshi's death, his wife, Kita no Mandokoro, became a nun and was given the dharma name "Kà Âdai-in " by Emperor Go-Yà Âzei in 1603. She then made a vow to build a temple to commemorate Hideyoshi's soul, and Tokugawa Ieyasu supported the construction. Kà Âdai-ji was built on the grounds of once belonging to a temple called Unkà Â-ji, which had burned down during the à Ânin War. The temple was begun by relocating structures from other temples in Kyoto. The Kotoku-ji, which contained the grave of Hideyoshi's mother à Âmandokoro was located was relocated to the new site. Kà Âdai-in built a residence and one for her nephew Kinoshita Toshifusa to the west of Kà Âdai-ji, and later that same year moved her palace and its front garden from Fushimi Castle to make it her own residence. He also moved the abbot's quarters and a chashitsu from Fushimi Castle. Tokugawa Ieyasu appointed Kyoto Shoshidai Itakura Katsushige as the magistrate of construction and having his subordinate samurai work on the construction of the temple Among them Hori Naomasa was particularly significant, and a wooden statue of Naomasa is enshrined in the Kaisan-do Hall (Founder's Hall) of Kà Âdai-ji. The new temple was consecrated in 1606 as a Sà Âtà  sect temple.
In July 1624, the temple converted from the Sà Âtà  sect to the Rinzai sect. Kà Âdai-in's brother Kinoshita Iesada, had close ties to the Rinzai temple of Kennin-ji, where one of his son's was a monk. Kà Âdai-in died later that year, and her palace was converted into the tatchà « sub-temple of Entoku-in by Kinoshita Toshifusa. It has since become the Kinoshita bodaiji.
On February 9, 1789, a fire broke out at KÃ Âdai-ji, destroying the small abbot's quarters and the Refrectory. In 1795, the former palace of KÃ Âdai-in, which had been located at Entoku-in, was dismantled and relocated to become KÃ Âdai-ji's abbot's quarters. However, this structure was burned down on July 26, 1863, by anti-shogunate agitators who were upset by news that Matsudaira Shungaku intended to use the building as his residence in Kyoto.. In 1867, a group of former Shinsengumi samurai who had defected to the imperial side made Gesshin-in, a sub-temple of KÃ Âdai-ji as their barracks. The group called themselves the "Imperial Throne Guards", claiming to be there to protect the tomb of Emperor KÃ Âmei, but were annihilated in the Shinsengumi November that year.
Most of the structures of KÃ Âdai-ji have been destroyed in fires, and the only structures remaining from the original construction are the Kaisan-do, the mausoleum (Otamaya), and to chashitsu teahouses. The interior decoration of the mausoleum (Otamaya) uses Momoyama-style lacquerware, which is called "Kodaiji lacquerware."
The android Mindar has given sermons on the Heart Sutra at KÃ Âdai-ji since 2019.
The temple possesses a number of objects designated as Important Cultural Assets. Among these are the Sanmon and the Otamaya, noted for its use of maki-e. Lacquerware has a tradition at this temple. The temple is nicknamed the "maki-e temple". One of the maki-e patterns used on a natsume tea utensil is called Kà Âdai-ji bun natsume (é«Âå°寺æÂÂæ£Â), featuring the imperial chrysanthemum seal and the paulownia seal of the regent.
The treasury also holds paintings, including one of Hideyoshi, as well as textiles, and a bronze bell with an inscription dating it to 1606.
