What is Omi Jingu Shrine? | The History of the Imperial Shrine Dedicated to Emperor Tenji
Founding and History of Omi Jingu Shrine
Omi Jingu Shrine is a relatively new shrine, founded in 1940 (Showa 15) with the permission of Emperor Showa. However, its historical background is ancient, as it is located on the site of the ancient capital, Omi-Otsu Palace, founded by Emperor Tenji in 667.
Emperor Tenji (626-672) was a great emperor who carried out the Taika Reforms and laid the foundation for Japan’s Ritsuryo state system. He made significant contributions to the development of Japanese culture, politics, and industry through the enactment of the Omi Code, the establishment of the school system, and the development of the household registration system.
Status as an Imperial Shrine
Omi Jingu Shrine is one of only 16 Imperial Shrines in Japan. An Imperial Shrine is a special shrine to which an imperial envoy is dispatched on behalf of the Emperor. Every year on April 20th, an imperial envoy is welcomed from the Imperial Palace for the annual festival, and a solemn ceremony is held.
This high status speaks to the magnitude of Emperor Tenji’s achievements in the formation of the Japanese nation. Omi Jingu Shrine is not merely a tourist destination, but an important place of reverence that conveys Japanese history and culture to the present day.
Deities and Divine Virtues of Omi Jingu Shrine
Emperor Tenji (Amemikoto Hirakasu Wake no Okami)
The principal deity of Omi Jingu Shrine is Emperor Tenji, whose divine title is “Amemikoto Hirakasu Wake no Okami.” This title embodies the meaning of an emperor who, receiving a divine command, ushered in a new era.
Emperor Tenji, as Prince Naka no Oe, together with Nakatomi no Kamatari, realized the Taika Reforms, transforming Japan from an ancient state to a Ritsuryo state. His reformist spirit and foresight continue to provide good fortune and guidance to many people even today.
Benefits as the Ancestor of Time
Emperor Tenji is known as the first emperor in Japan to install a water clock (rokoku) and begin timekeeping. On April 25, 671 (lunar calendar), Emperor Tenji installed a water clock at Omi Otsu Palace and announced the time to the people by striking bells and drums. This is considered the beginning of the timekeeping system in Japan.
Based on this historical fact, Omi Jingu Shrine is revered as the “ancestral deity of time,” and is believed to grant blessings for keeping to schedules, using time effectively, and not missing opportunities. It enjoys particularly strong devotion from those in the watch industry and time-related professions, and a grand “Rokoku-sai” (Water Clock Festival) is held every year on June 10th, “Time Memorial Day.”
Blessings as a Great Deity of Good Fortune and Guidance

It is believed to grant blessings for passing exams, finding employment, business success, and finding a good partner, guiding people down the right path at important junctures in life, and many worshippers visit to pray.
Guardian Deity of Culture, Arts, and Industry

Therefore, it is believed to bring blessings for academic success, technological advancement, and industrial development.
It is particularly revered by students, researchers, engineers, and business owners—those in professions that utilize knowledge and skills.
Omi Jingu Shrine as a Sacred Site for Karuta
Hyakunin Isshu and Emperor Tenji
The reason Omi Jingu Shrine is known as a “sacred site for karuta” stems from the fact that the first poem in the Hyakunin Isshu is a poem composed by Emperor Tenji.
“In the autumn rice fields, in the temporary hut, the thatched roof is rough, and my sleeves are wet with dew.”
This poem expresses Emperor Tenji’s compassion for the hardships of his people, and is a dignified work befitting the opening of the Hyakunin Isshu. Due to this historical connection, Omi Jingu Shrine is positioned as the headquarters of competitive karuta.
