Overview

Goshikinuma Ponds is a group of vividly colored volcanic ponds located in Urabandai, Fukushima Prefecture, northeastern Japan. The name “Goshikinuma” means “Five-Colored Ponds,” reflecting the remarkable range of colors seen in the water—blue, emerald green, turquoise, and even reddish hues—depending on mineral content, light conditions, and weather.

The ponds were formed after the 1888 eruption of Mount Bandai, which dramatically reshaped the landscape. Today, Goshikinuma is one of the most scenic and accessible nature attractions in the Tohoku region.

Geological Background

The 1888 Mount Bandai Eruption

In July 1888, a massive phreatic (steam-driven) eruption caused part of Mount Bandai to collapse. The eruption:

• Destroyed villages

• Redirected rivers

• Created numerous lakes and ponds

Minerals released from volcanic debris dissolved into the water, producing the ponds’ distinctive colors. This geological history is key to understanding why each pond looks different.

The Goshikinuma Nature Trail

Trail Overview

The Goshikinuma Nature Trail is a well-maintained hiking path that connects the main ponds.

• Length: approximately 3.6 kilometers

• Walking time: about 60–90 minutes at a relaxed pace

• Difficulty: easy to moderate

• Surface: mostly flat with gravel paths and wooden boardwalks

The trail is suitable for most visitors, including families and casual hikers.

Major Ponds Along the Trail

The largest and most famous pond in the area. Its deep cobalt-blue water changes color depending on sunlight and season. Rowboats are available, offering a rare chance to view the pond from the water.

Aonuma

A striking bright-blue pond known for its clarity. Swimming and fishing are prohibited to protect the fragile ecosystem.

Rurinuma

Named for its lapis lazuli-like color, this pond is especially beautiful on clear days.

One of the first ponds encountered on the trail, featuring softer green tones and surrounding forest reflections.

Each pond has unique chemical characteristics, resulting in different colors even when located only meters apart.

Seasonal Highlights
