Held from spring to autumn Fishing for Japanese eels in the brackish waters of rivers Part 1: 8:00-10:30 Part 2: 10:30-13:00 Part 3: 13:30-16:00 Part 4: 16:00-18:30 This is a tour to fish for eels at the mouths of rivers that run through Tokyo. Japanese eels are born in the western waters of the Mariana Islands. They grow in rivers not only in Japan but also in East Asia, including China, Taiwan, and the Korean Peninsula, and are known to return to the Mariana Islands to spawn. Japanese eels (Anguilla japonica), which belong to the Anguilla genus of the eel family, are widely distributed in East Asia, including Japan, China, Taiwan, and Korea. In Japan, they mainly live south of Honshu, but there have been cases of them being caught in Hokkaido. Rental tackle, fishing rod, and equipment are included, so you can participate empty-handed. Two patterns of fishing are done: casting fishing and plastic bottle tackle fishing, using earthworms as bait. While waiting for the tackle, you can fish for goby at your feet. The main target is eels, but sometimes you can catch gobies, crabs, and seigo. The tour lasts about 3 hours. Please bring a headlamp, a handy light, and drinks. *If you want to take something home, please bring an aeration device (battery-powered bubbler) to prevent oxygen deficiency, a plastic case or fishing bucket to prevent escape, and a cooler box. By train: 15 minutes walk from JR Joban Line or Tokyo Metro Chiyoda Line By car: Please use a nearby parking lot. Meeting place: Near the Seven-Eleven Katsushika Kosuge 1-chome store. We will send you a map in advance, so please walk to the point. Migration of Japanese eels Japanese eels spawn in the summer in the waters west of the Mariana Islands in the Pacific Ocean. After hatching, they become larvae that look like willow leaves, called leptocephalus. They are carried by the glass eel current and reach East Asia in about six months, when they transform into long, cylindrical glass eels and enter rivers on the high tide. After that, their transparent bodies start to take on color and they are called yellow eels. During the yellow eel stage, the eels grow large and eat a variety of food, including shrimp, crabs, small fish and insects. Japanese eels spend their growth period in a wide range of environments, from coastal areas to the upper reaches of rivers, including not only freshwater but also brackish and marine areas. After several to a dozen years, when they reach a size of over 40 cm for males and over 50 cm for females, they begin to mature and are called silver eels. From autumn to winter, silver eels leave the rivers and coastal areas that they are accustomed to living in and travel to spawning grounds. It takes about six months to reach the spawning grounds in the Marianas, where they spawn and then end their lives.
