History
During the Edo period the Shinmachi River was a very busy area due to the travel of boats carrying Indigo Dyeing wares, one of the main trades supporting finance in the region at the time.Geography
The Shinmachi River runs through the middle of the capital city of Tokushima Prefecture - Tokushima City, and passes by many well known tourist spots within the city area.Water
Up until the early Shōwa period, the condition of the river was so good as to allow people to swim there during the summertime. However, in the coming years the river became increasingly polluted and thus unsuitable for swimming. Efforts in recent years to clean up the river have improved its overall condition greatly, but there still remains some sludge on the bottom of the river and it has yet to return to its former glory.Main events along the waterway
