by A poignant Japanese folk tale from Lake Biwa has been brought to life through animation. The short anime film “Oman-san” was recently completed and officially presented to Moriyama City officials as part of a cultural preservation initiative.
The five-minute animated film retells a tragic love story rooted in local folklore while highlighting the dangers of Lake Biwa’s powerful winds. The project aims not only to preserve traditional stories but also to pass their lessons on to younger generations.
A Folk Tale Preserved Through Animation
The anime adaptation of Oman-san was produced by the Japan Folk Tale Association in collaboration with the The Nippon Foundation.
Project Highlights
- Started: 2018
- Total animated works: 92
- Participating municipalities: 90
- Shiga Prefecture stories: 5 including Oman-san
The initiative seeks to preserve local traditions while teaching children about nature, safety, and cultural heritage.
The Story of “Oman-san”
The anime tells a heartbreaking love story set around Lake Biwa.
Oman, a young woman from Kagami Village, falls in love with Hachiko, a young man from Hira Village. Their relationship begins after Hachiko defeats her in a sumo wrestling match.
When Oman confesses her feelings, Hachiko responds with a difficult challenge:
“If you cross the lake to visit me for one hundred nights, I will marry you.”
Determined to prove her devotion, Oman travels across Lake Biwa night after night, guided only by a small lamp.
However, tragedy strikes on the hundredth night.
A powerful wind known as “Hira-oroshi” blows down from the Hira Mountains toward Lake Biwa. The wind extinguishes Oman’s guiding lamp, leaving her lost in darkness.
Unable to find her way across the lake, she tragically sinks beneath the water.
The Meaning Behind the Legend
Although the story is tragic, the legend carries an important lesson.
The tale warns people about the dangers of sailing on Lake Biwa and reminds them to respect nature.
Lessons from the Story
- Understand local winds and weather conditions
- Respect the dangers of water travel
- Pass down traditional knowledge about nature
The Hira-oroshi wind is still known today as a powerful seasonal wind that can quickly create dangerous waves on the lake.
Local Traditions and the Oman Festival
The story of Oman continues to live on in the Imahama district, a community located along Lake Biwa.
Several variations of the legend exist in the region, including stories that claim:
- The guiding lamp was blown out by “eight peaks of wind.”
- Oman’s spirit still protects travelers near the lake.
To honor the legend, a memorial festival dedicated to Oman is held in the area every year.
The festival celebrates both the story itself and the cultural history of the region.
Anime DVD Presented to Moriyama City
After completing the animation, project representatives visited Moriyama City Hall to donate the film to the local government.
Among those present were:
- Shinnosuke Numata, representative director of the Japan Folk Tale Association
- Kazuhiro Imaeda, chairman of the Imahama Neighborhood Association
They presented the DVD to Moriyama Mayor Takashi Morinaka.
Mayor Morinaka’s Comment
The mayor praised the project, saying the anime is a valuable educational tool that teaches viewers about both the beauty and dangers of Lake Biwa.
He also noted that although the story is sad, it delivers an important message that children can understand.
Inspiring Interest in Folklore
According to Shinnosuke Numata, the animation project aims to spark curiosity about regional history and traditional storytelling.
He hopes the film will encourage young viewers to:
- Learn about local folklore
- Research traditional stories
- Appreciate the cultural heritage of their communities
By presenting folk tales in an accessible animated format, the project helps keep these stories alive for future generations.
Where to Watch the Anime
The animated short film “Oman-san” is approximately five minutes long and can be watched online.
It is available on the “Sea Folktales Project Channel” on YouTube.
This allows viewers across Japan and around the world to experience the touching story and learn about the cultural traditions of Shiga Prefecture.
Why Projects Like This Matter
Japan has thousands of regional folk tales, many of which risk being forgotten as communities change.
Animation projects like this help:
- Preserve traditional stories
- Educate younger generations
- Promote regional culture and tourism
- Share local history with a global audience
By combining modern animation with centuries-old folklore, stories like Oman-san can continue to inspire audiences for years to come.
