2. About 片倉ダム

A Brief Description

• Location: Kawaguchi, Chiba Prefecture, Japan
• Coordinates: 35.202035° N, 140.073445° E
• Type: Concrete dam (primary purpose: water supply and flood control)

While the exact height and altitude of Katakura Dam are not publicly listed, its modest scale makes it an ideal spot for leisurely walks and quiet contemplation. The dam forms part of the larger water‑management network that supports agriculture and residential needs across the northern Chiba plain.

History & Significance

Katakura Dam was constructed in the post‑war era as part of Japan’s nationwide push to modernize water infrastructure. Though it never achieved the fame of larger structures like the Kurobe Dam, it has quietly served the local community for decades, ensuring a reliable water source for nearby farms and towns.

Because the dam sits within a relatively untouched forested area, it also plays an ecological role: the reservoir creates a habitat for various bird species, amphibians, and small mammals. Seasonal migrations often bring a flurry of activity, making the site a subtle hotspot for nature observation.

Why It Matters to Travelers

• Low Crowds: Unlike major tourist dams, Katakura Dam rarely sees large groups, allowing you to soak in the scenery at your own pace.
• Scenic Contrast: The crisp, blue water against a backdrop of gently rolling hills creates striking photo opportunities, especially during sunrise and autumn foliage.
• Gateway to Waterfalls: Within a 5‑km radius you’ll find several picturesque waterfalls—perfect for a day‑trip itinerary.

3. How to Get There

From Tokyo

1. Train: Take the JR Sobu Line (Rapid) from Tokyo Station to Kawaguchi Station (≈ 45 minutes).
2. Bus or Taxi: From Kawaguchi Station, board the local bus heading toward Katsushika‑Kita (check the latest timetable at the station) or hail a taxi. The ride to the dam’s parking area takes about 15 minutes.

By Car

• Route: From the Keiyo Road (E1), exit at Kawaguchi‑Interchange and follow the signs for Katsuta‑Road (県道 71号). The dam is signposted a few kilometres after the junction.
• Parking: A small free lot sits near the visitor’s pavilion; it fills quickly on weekends, so early arrival (around 9 AM) is advisable.

Public Transportation Tips

• IC Cards: Suica or Pasmo work on both JR trains and local buses.
• Bus Frequency: Buses run roughly every 30 minutes on weekdays; weekends may see reduced service, so check the Chiba Bus website beforehand.

4. Best Time to Visit

Pro tip: The nearby waterfalls are at their most dramatic after a rainstorm, especially in late spring and early autumn. Check local weather forecasts and plan accordingly.

A short, well‑maintained trail circles the reservoir, offering multiple viewpoints:

• East Viewpoint: Overlooks the dam wall with the surrounding hills rising in the background.
• North Picnic Spot: A flat grassy area equipped with benches—perfect for a lunch break.

Bring a wide‑angle lens to capture the expanse of water against the forested horizon. Early morning light often creates a soft golden glow, while late afternoon can produce dramatic shadows on the dam structure.
