Okama Crater Lake (Goshiki Lake)
Lake Gokako, situated at the highest elevation within the Zao mountain range, is a volcanic crater lake. Enclosed by three peaks - Kattadake, Kumano Peak, and Goshikidake - this lake spans a diameter of 325 meters and has a circumference of about 1 km. Due to varying factors such as season, time of day, weather, and temperature, the lake's water changes in colors, ranging from deep green, blue, to emerald green. This has earned it the moniker " Goshiki Lake (Five-Colored Lake)." The serene shimmer of the lake's surface contrasts sharply with the rugged volcanic walls, creating a profound sense of natural beauty.
Getting the chance to see Zao's iconic Okama Crater in person is definitely a journey that requires a bit of luck. Even when the sky is perfectly clear at the foot of the mountain, the weather on the way up can often change in an instant, with clouds and fog rolling in. I was very lucky to have good weather during my summer visit and immediately saw the dazzling blue-green crater lake, shining like a jewel, with patches of unmelted white snow dotting the slopes. It's hard to imagine the impact of nature's extraordinary power in creating such a unique and magnificent landscape without seeing it for yourself.
After arriving at Okama Crater, you can easily get closer for a view by following the gentle walking path. If you want a full view of the entire crater and the magnificent surrounding mountains, I definitely recommend climbing up to the shrine at the top, where the highest point offers an excellent panoramic view. Standing quietly and gazing at this emerald-green lake, formed by a volcanic eruption tens of millions of years ago, I was filled with emotion and awe. It's definitely a dreamlike spot you must visit when traveling in Tohoku.
