Okama

Okama is a crater lake situated in the Zao Mountain Range, spanning the border between Miyagi and Yamagata Prefectures in northern Japan.

The best time to visit is from late May to October when the roads are open and the weather is clear enough to see the lake's vibrant colors.

You can reach it by car via the Zao Echo Line and Zao High Line, or take a seasonal bus from JR Yamagata Station or Kaminoyama Onsen Station.

There is no entrance fee to view the lake, but there is a toll for vehicles using the Zao High Line road that leads to the observation deck.

No, the roads leading to Okama (Zao Echo Line) are closed from early November to late April due to heavy snowfall.

It is nicknamed 'Goshiki-numa' because the water's emerald green color changes into various shades depending on the angle of sunlight and weather conditions.

Most visitors spend about 1 to 2 hours enjoying the view from the observation deck and walking along the nearby trails.

Even in summer, it can be windy and chilly at the summit. It is recommended to wear layers and sturdy walking shoes.

Yes, the Zao Sancho Rest House near the parking lot offers a restaurant, souvenir shop, and public restrooms.

Nearby highlights include Zao Onsen, the Zao Ropeway, and various hiking trails throughout the Zao Mountain Range.
