The Yoshino River Shirauo fishing is a traditional fishing method that has been practiced for generations near the mouth of the Yoshino River in Tokoshima Prefecture. The focus of this activity is the 'Shirauo' (glass eel), the juvenile stage of the eel. To catch these young eels as they migrate from the sea into the river, fishing boats use powerful lights to illuminate the dark river surface. The sight of countless particles of light floating in the pitch-black darkness is incredibly beautiful, resembling stars descending onto the river. It is a breathtaking landscape born from the harmony of natural cycles and human tradition.
This fishing method is deeply intertwined with the rich natural environment of the Yoshino River. The techniques and knowledge required to catch the glass eels as they migrate upstream have been passed down through generations. Beyond being a mere commercial fishing activity, it is a celebrated winter tradition that fascinates both locals and visitors alike. This ritual, performed under specific seasonal and natural conditions, serves as a precious symbol of Japan's riverside culture.
The greatest highlight is the 'sea of light' that spreads across the mouth of the Yoshino River in the middle of the night. The intense light from the fishing boats reflects off the water, creating a dramatic atmosphere in the silent night. Because the reflection changes based on the tides and weather, the scenery offers a different expression every time you visit. The sight of boats moving through the river provides a mystical beauty that makes it a highly sought-after subject for photographers.
The primary season for this fishing activity is from mid-December to late April. It is most active during the winter months of December, January, February, March, and April. The fishing typically takes place during the late-night hours, roughly between 1:00 AM and 4:00 AM. Please note that the activity is influenced by the lunar cycle; during full moons, the glass eels become more sensitive to light, which may lead to fewer boats being out, thus changing the visual intensity. The most active times are generally from low tide to high tide around spring tides.
The main activity here is observing the traditional fishing landscape and photography. The light displays created by the boats offer a unique experience that cannot be seen in daily life. Observing the movement of light against the silence of the river allows you to feel the power of Japan's nature and traditional industries. *Note: If you wish to actually board a fishing boat, prior confirmation is required.
The area around the Yoshino River is dotted with spots where you can experience the rich nature and history of Tokushima. When visiting the river mouth, you can plan a sightseeing route that includes nearby hot spring facilities (onsen), historical buildings in Tokushima, or local restaurants. Since the activity occurs late at night, it is essential to check local accommodation and transportation options in advance.
As this is an outdoor activity at night, heavy winter clothing is mandatory. Temperatures in the middle of the night during winter are extremely low, so please prepare thick jackets, gloves, and heat packs (kairo). Since the area can be dark and uneven, wear sturdy shoes with good grip. While most local services may require cash, please be prepared for any incidental expenses. For photography, please maintain a respectful distance to avoid interfering with the fishing operations.
