Hōkoku Shrine, Shinto shrine in Osaka Castle Park, Japan

Hōkoku Shrine stands on the south side of the ninomaru of Osaka Castle. Its worship hall has a copper-green roof rising to a curved gable with a small finial, a gilded bird relief above the entrance, and six light-gray columns with dark bases; two low staircases lead to a raised wooden floor. A stone pedestal to the right holds a seated bronze animal and a carved emblem. The 2007 bronze statue of Toyotomi Hideyoshi by sculptor Shinya Nakamura is 3.2 m tall on a 2 m pedestal.

Built in 1879 under orders from the Meiji Emperor, Hōkoku Shrine was established to honor Toyotomi Hideyoshi, a military leader who helped unify Japan during the late 16th century, and also enshrines his half-brother Hidenaga and his son Hideyori.

The shrine's name is read Hōkoku, unlike the Toyokuni reading used at the Kyoto shrine of the same name. Its main festival, the Taikō-sai, is held on 18 August, the date in the old lunar calendar on which Toyotomi Hideyoshi died in 1598. In 2015, to mark the 480th anniversary of Hideyoshi's birth, a New Year rite placed his favourite foods, barley rice and matcha, before the main hall.

The shrine stands on the south side of the Ninomaru of Osaka Castle, within Osaka Castle Park. Walking times from stations are about 19 minutes from Morinomiya (JR Loop Line or Osaka Metro Chuo and Nagahori Tsurumi-ryokuchi lines) and about 19 minutes from Tanimachi 4-chome (Chuo and Tanimachi lines). The Osaka Castle Road Train stops right in front at the Sakura-mon stop, and city buses serve Babamachi and Otemae stops.

The shrine houses a modern dry rock garden called Shuseki-tei, designed by landscape artist Mirei Shigemori in 1972, which is usually closed but can be viewed from outside during special times like Golden Week and New Year holidays.
