History of Nagara Bridge
From the First Bridge to the Present Structure
The first Nagara Bridge was completed in 1909 as the first bridge across the newly formed Yodo River. It was constructed by repurposing a bridge originally used by the Tokaido Main Line.
A second Nagara Bridge was completed in 1936. However, near the end of World War II, the bridge became the site of the Nagara Bridge Tragedy when it was attacked by U.S. Navy carrier aircraft on June 7, 1945, resulting in numerous deaths.
After the war, the bridge underwent repairs. In 1964, the Nagara Bypass was added to accommodate increasing traffic.
The present Nagara Bridge was built through a reconstruction project that began in 1973 and was completed in 1983. It continues to serve as an important transportation link in Osaka.
Ancient Nagara Bridge and Its Legends
A Bridge with Ancient Origins
The name Nagara Bridge also appears in ancient Japanese literature. According to tradition, a bridge known as Nagara Bridge was built in 812, during the reign of Emperor Saga.
However, this ancient bridge is believed to have stood in a different location from today’s bridge, reportedly connecting an area around Higashimikuni in Yodogawa Ward with what is now Suita City.
The bridge was later destroyed by flooding. It was not rebuilt during the medieval period and gradually came to be remembered as a mysterious and evocative place in Japanese literature.
Nagara Bridge in Japanese Poetry
Nagara Bridge has appeared in numerous waka poems and other works of Japanese poetry, where it was often portrayed symbolically as a bridge falling into decay.
The poet Akazome Emon, for example, wrote of the bridge:
“The Nagara Bridge has decayed, it seems, and the passing of everything in Naniwa brings a sadness of old.”
The Kamakura-period poet Fujiwara no Ietaka also composed a poem referring to Nagara Bridge:
“If it were rebuilt in your reign, how many thousands of times would I cross the Nagara Bridge of Tsu Province?”
The Human Pillar Legend
A Tragic Tale Behind the Bridge
Nagara Bridge is associated with a famous human pillar legend. According to the story, construction of the bridge repeatedly encountered difficulties, and a human sacrifice was proposed as a way to ensure that the project would succeed.
The legend tells of a man who was passing near the bridge with his wife and child. He jokingly suggested that someone whose hakama, a traditional Japanese garment, had been mended should be chosen as the human pillar.
Unfortunately, the man’s own clothing met the condition he had described. He was therefore selected as the sacrifice, turning his careless joke into a tragic fate.
How the Legend Spread
The story was passed down in various forms and was also recorded in essays and other writings during the Edo period.
It is traditionally associated with the Japanese proverb “The mouth is the source of misfortune”, expressing the idea that careless words can bring trouble upon oneself.
Today, a monument commemorating the human pillar remains at Daiganji Temple in Higashimikuni, Yodogawa Ward, Osaka.
A Memorial to Air Raid Victims
Meirin Kannon Bodhisattva
On the south side of Nagara Bridge stands a statue of Meirin Kannon Bodhisattva.
The statue was erected to pray for the peaceful repose of people who lost their lives in the air raid of June 7, 1945, as well as victims of accidents and disasters in the Yodo River.
The monument provides a place for visitors to remember those who lost their lives and reflects the difficult history surrounding the bridge.
