Okama Crater Lake

🌋 Okama Crater Lake (御釜)

(Okama – The “Five Color Pond”)

Okama is a stunning volcanic crater lake located on Mount Zao, which straddles the border between Miyagi Prefecture and Yamagata Prefecture in northern Japan. It is famous for its strikingly beautiful, vivid colors that change depending on the weather, earning it the nickname “Five Color Pond.”

🌈 Why “Five Color Pond”?

  • The water of Okama Lake reflects different colors — from emerald green to deep blue, turquoise, and other hues — depending on sunlight, weather, and seasons.

  • This natural phenomenon makes the lake a spectacular sight for visitors and photographers alike.

🌋 About the Crater

  • Okama is a caldera formed by volcanic activity on Mount Zao.

  • The crater is roughly 360 meters in diameter and about 60 meters deep.

  • The lake itself was created by rain and snow filling the volcanic crater.

🗻 Mount Zao and Surroundings

  • Mount Zao is an active volcano known for its beautiful geothermal activity, hot springs (onsen), and ski resorts.

  • The area around Okama features hiking trails, scenic viewpoints, and the famous “snow monsters” (frost-covered trees) in winter.

🚗 How to Visit Okama

  • The easiest access is by car or bus from nearby towns such as Yamagata City or Sendai City (Miyagi Prefecture).

  • Visitors usually park at the Okama Viewing Platform and walk a short trail (about 20 minutes) to get panoramic views of the crater lake.

  • The road is generally open from late spring to autumn (usually from late April or May to November), as winter snows block access.

🏞️ Best Time to Visit

  • Summer and early autumn: Clear skies and vibrant colors in the lake.

  • Autumn: The surrounding mountains are covered in colorful fall foliage, enhancing the views.

  • Winter: The area is closed due to heavy snow, but the nearby Zao Ski Resort offers famous snow monster sights.
