The path they walked

574

Birth

Born a son of Emperor Yōmei; his mother was Princess Anahobe no Hashihito. He was named Umayado ("stable door"), from a legend that his mother went into labor in front of a stable.

587

Teibi Incident

Soga no Umako, who embraced Buddhism, fought Mononobe no Moriya, who opposed it. The 13-year-old prince joined the Soga side and, it is said, carved images of the Four Heavenly Kings to pray for victory, later founding Shitennō-ji as promised.

593

Assisting the throne

When his aunt Empress Suiko took the throne, he became crown prince and helped govern as regent, working with Soga no Umako. The legend that he could hear ten petitions at once reflects his famed wisdom.

594

Promoting Buddhism

The empress issued an edict to promote Buddhism, and the great clans vied to build temples. The prince led the way in spreading the teachings.

595

Learning from Eji

He took the Goguryeo monk Eji as his teacher, studying Buddhism and continental learning in depth. The Baekje monk Esō also arrived and joined in spreading Buddhism.

601

Ikaruga Palace

He began building a palace at Ikaruga in Nara and later moved there; this spot a little apart from Asuka became the base of his work.

603

Twelve Cap Ranks

He set up the Twelve Cap Ranks, promoting officials by talent and merit rather than birth. Ranks were shown by cap colors, aiming at a state less dependent on clan power.

604

Seventeen-Article Constitution

He issued the Seventeen-Article Constitution, opening "Harmony is to be valued", setting out how officials should behave: settle things by discussion, revere Buddhism, obey the sovereign.

607

Envoy to Sui and Hōryū-ji

He sent Ono no Imoko to Sui China. The letter beginning "The Son of Heaven where the sun rises, to the Son of Heaven where the sun sets" reportedly displeased Emperor Yang. Around then he is said to have built Hōryū-ji at Ikaruga.

608

Sending students

Imoko returned with the Sui envoy Pei Shiqing. That year the prince sent Imoko again, along with students such as Takamuko no Kuromaro and the monk Min, whose learning would later underpin the Taika Reforms.

615

Commentaries on three sutras

He is said to have compiled the Sangyō Gisho, commentaries on three Buddhist sutras (whether he wrote them himself is debated).

620

Recording history

With Soga no Umako he compiled the chronicles Tennōki and Kokki, the first attempt to record the country's origins.

622

Final days

After his mother, his consort fell ill and died, and the next day the prince died at 48. People mourned as if they had lost a parent. His consort Tachibana no Ōiratsume preserved his words "The world is illusion; only the Buddha is true" in an embroidery, the Tenjukoku Mandala. Today he is sometimes called Umayado-ō, and his achievements are debated.
