Daimyo of Aki who built the Mōri domain
A daimyo of Aki Province from the mid- to late Sengoku period, head of the Mōri clan and unifier of the Chūgoku region (the San'yō and San'in districts), rising from a small lord of a single province in Aki to ruler of about ten provinces in Chūgoku — the classic Sengoku case of the small overcoming the great.
People & stories
Places in their life
He was born at Suzuo Castle in Aki Province (his mother's home). His father Mōri Hiromoto retired in 1500 and died in 1506; after his elder brother Okimoto's death, Motonari succeeded as head of the clan in 1523 following the death of his nephew Kōmatsumaru. His base was Yoshida-Kōriyama Castle (present-day Akitakata, Hiroshima Prefecture). In 1540 he defeated the Amago army at Yoshida-Kōriyama Castle; in 1555 he defeated Sue Harukata at Itsukushima, inheriting the Ōuchi domains at a stroke; in 1566 he captured Gassantoda Castle and destroyed the Amago clan. In the end he controlled about ten provinces — Aki, Suō, Nagato, Bitchū, Bingo, Inaba, Hōki, Izumo and Iwami, plus parts of Buzen and Sanuki. In his later years he made peace with the Ōtomo and gave up control of Hakata, and refused to join the anti-Nobunaga encirclement (declining even Ashikaga Yoshiaki's invitations after 1570). He died of illness at Yoshida-Kōriyama Castle in 1571, the cause given variously as oesophageal cancer or old age.

Cultural significance
Motonari is the symbol of the strategist: the victory against the odds at Itsukushima and the "Three Arrows" teaching story (a father showing his three sons that three arrows together cannot be broken, symbolising unity — a famous later teaching tale, to be marked as legend, not confirmed fact) are told to this day. The nickname "Beggar Prince" appears in fan sources and is used with caution; this text does not adopt it. Akitakata City brands itself as the Mōri homeland, and the Yoshida-Kōriyama Castle ruins and Motonari's grave are associated sites.

Gassan-Toda Castle Ruins — the historical setting
Gassan-Toda was the Amago clan's main castle, famed for its impregnability and counted among the five great mountain castles of the Sengoku period; both the Ouchi and the Mori failed to take it by direct assault. In 1564–1566 Mori Motonari switched from siege to starvation, and Amago Yoshihisa surrendered and opened the castle in 1566, ending the Amago.
History · Yoshida-Koriyama Castle Ruins
Yoshida-Koriyama Castle Ruins — the historical setting
Yoshida-Koriyama was the Mori clan's main castle, from which Mori Motonari expanded; in the 1540 Battle of Yoshida-Koriyama, Motonari's defenders repelled the large attacking army of Amago Haruhisa — attacking numbers vary by source, so only the scale is stated — a key step in the Mori rise.

Mōri Motonari and the three arrows
The tale of three arrows teaches unity among Mōri Motonari’s sons. Akitakata City presents it as a traditional anecdote; the teaching scene is not a verified historical event.
