ToggleBiei Shirogane Blue Pond (Hokkaido)

The “Blue Pond” in Japan is a captivating and mysterious spot where the calm waters reflect the surrounding trees like a mirror. This natural wonder becomes even more enchanting from November to February when it’s illuminated, drawing couples for romantic photos. Cool off with their exclusive “Blue Lake Soft Serve” or “Blue Lake Soda” as you take a stroll along the pond.
The pond’s striking blue or emerald hue is due to high aluminum levels in the water, which scatters short-wavelength blue light. The Blue Pond is sourced from the Biei River and a tributary near Shirogane Onsen, which carries sulfur and other minerals. When these waters mix, they create invisible “colloids.”
Sunlight scattering off these colloids emphasizes the blue light, giving the pond its unique color. Additionally, the white soil at the pond’s bottom may enhance this blue effect, making the colors even more vivid.
Be sure to set aside plenty of time for your visit, as the designated parking lot can fill up, leading to delays in getting in and out. The best way to get there is by car or a tour bus.

Lake Mashu (Hokkaido)

Lake Mashu, known as “Kamuito” in the Ainu language, is often called the “Lake of the Gods” due to its mysterious allure and stunning beauty. Renowned for having the clearest waters in Japan, its deep blue color, known as “Mashu Blue,” shifts with the movement of clouds, creating a mesmerizing spectacle. The blue hue is a reflection of the sky on the lake’s pristine waters, which appear even more vivid on calm, windless days.
Surrounded by steep cliffs, Lake Mashu is inaccessible by foot, adding to its enigmatic charm. As part of a specially protected national park, this mystical lake has drawn visitors for generations, captivated by its ethereal beauty and tranquil atmosphere.
If the weather is right, you can catch a stunning sea of clouds from June to October. The combination of the deep-blue lake and the glowing sunrise is one of the most incredible sights you’ll ever see.
Don’t miss its breathtaking views from the observation deck and the beautiful hike around the lake. Lake Mashu is a 15 to 20-minute drive from Mashu Station in Teshikaga. While the easiest way to reach it is by car, buses run occasionally between the station and the lake year-round. Public transportation options are available, but they are limited.

Shimako (Gunma)

Experience the captivating “Shimako Blue” of Lake Shimako, located in the Agatsuma District of Gunma Prefecture. The Shimako is easier to reach from Tokyo compared to the other scenic spots introduced in this article. This artificial lake, formed by the Nakanojo Dam near the picturesque Shimura Onsen, is renowned for its striking and ever-changing blue hues.
The lake’s 4-kilometer perimeter can be explored by car, though driving is not possible in winter. You can also enjoy water activities like canoeing and stand-up paddleboarding (SUP) on its remarkably clear waters.
Paddling on the lake provides a unique sensation of floating in mid-air. Many visitors join canoe tours organized by companies such as Green Discovery. However, if you have your own canoe or boat, you can arrange to use it by contacting the dam management office in advance. Enjoy both the stunning views and immersive water activities.
The best time to view this enchanting color is from late March to late May when the lake, filled with snowmelt, shines most brightly under a clear sky.
