The Witch Hat Intake Tower, officially part of the Kanamachi Purification Plant, stands as a unique piece of industrial architecture on the Edo River. Established in 1926, the plant expanded in 1941 with the addition of this second intake tower, notable for its red brick construction and distinctive triangular roof, which has earned it the whimsical nickname "witch hat." It has gained a degree of local fame, appearing in popular Japanese series like It’s Tough Being a Man and Tokyo Beat Cops, making it an unexpected icon for those familiar with the area's cultural references.
Visitors often appreciate the tower's quaint and somewhat anachronistic appearance, especially when viewed from a distance across the river. Its charm lies in its unusual design and its role as a quiet, unassuming landmark. There are no direct visitor facilities or tours, as it is part of an active water purification plant. The experience is primarily about observing the structure from public vantage points.
For those interested in visiting, the best approach is to view the tower from the opposite bank of the Edo River, where there are public walkways. It's recommended to allocate about 30 minutes to an hour for the visit, primarily for walking to a good viewpoint and taking photographs. There are no specific opening hours or entry fees as it is viewed from public spaces. Consider bringing a camera with a good zoom lens to capture details of the tower from across the river. The area around the tower is residential and offers limited tourist amenities, so plan accordingly for food and drinks.
To reach the Witch Hat Intake Tower, take the JR Joban Line to Kanamachi Station. From there, it's approximately a 15-20 minute walk to the Edo River. Alternatively, local buses might serve the area closer to the riverbank. Driving is an option, but parking can be limited in residential areas. The tower is visible from the river path, offering clear views without needing to enter the purification plant grounds.
A common complaint is the lack of direct access to the tower itself, as it is part of an active industrial facility. Visitors should manage expectations that this is a viewing experience from a distance rather than an interactive attraction. The surrounding area is not a major tourist hub, so combine a visit with other local activities if possible to make the trip more worthwhile.
