2. About 花貫ダム
What Is It?
花貫ダム is a concrete gravity dam built on the Hananuki River (花貫川) in the northeastern part of Ibaraki. Though the exact height and altitude are not publicly disclosed, the structure plays a vital role in regional water management and hydro‑electric power generation. The dam’s reservoir stretches across a serene basin, creating a mirror‑like surface that reflects the surrounding forest and seasonal sky colors.
History & Sign‑ificance
Constructed in the latter half of the 20th century, the dam was part of Japan’s post‑war infrastructure push to secure reliable water supplies for agriculture, industry, and local communities. Over the decades, it has become more than a utilitarian facility; it’s now a scenic landmark that draws hikers, cyclists, and families from across the Kanto region.
The dam’s proximity to the 花貫川第一発電所取水堰 (Hananuki River First Power Plant Weir) underscores its importance in the local energy network. Yet, the real charm lies in its peaceful setting—perfect for unwinding after a hectic city life.
3. How to Get There
By Train
- Tokyo → Takahagi – Take the JR Joban Line (Rapid or Local) from Ueno or Tokyo Station to Takahagi Station. The journey takes roughly 2 hours.
- Takahagi Station → 花貫ダム – From the station, hop on a local bus bound for Hananuki River (look for signs “花貫川方面”). The bus ride is about 15 minutes and drops you at a stop within walking distance of the dam.
By Car
- From Tokyo: Drive north on the Jōban Expressway (E6), exit at Takahagi Interchange. Follow Route 6 (国道6号) for ~10 km, then turn onto Ibaraki Prefectural Road 115 toward the dam. The total drive is ~130 km, about 2 hours in moderate traffic.
- Parking: A small free parking lot sits near the dam’s visitor area. Spaces fill quickly on weekends, so arriving early (8:00 – 9:00 am) is advisable.
By Bike
For the adventurous, the JR Joban Line stations are bike‑friendly, and a rental bike can be secured at Takahagi Station. The scenic route along the river is relatively flat, making it a pleasant 10‑km ride to the dam.
