The Mysteries of Lake Tazawa: Exploring the Secrets and Legends Behind Japan’s Deepest Lake

The Deepest Lake in Japan

Lake Tazawa is a mystical body of water located in the Akita Prefecture of Japan. With a depth of 423 meters, it is the deepest lake in Japan and one of the deepest in the world. It is fed by hot springs and surrounded by beautiful mountains, making it a popular destination for tourists and locals alike.

The Legend of Tatsuko

There is an old legend that surrounds the formation of Lake Tazawa. According to the legend, a beautiful girl named Tatsuko lived in a nearby village. One day, she fell in love with a god who had come down from the mountains to bathe in the hot springs. They fell deeply in love and promised to be together forever. However, their love was not meant to be. Tatsuko was actually a dragon princess who had taken on a human form, and because of this, they were forbidden to be together. The god returned to the mountains, leaving Tatsuko heartbroken. She decided to take her own life by jumping into the nearby marsh, which transformed into Lake Tazawa upon her death.

The Hidden Treasures of Lake Tazawa

Another mystery that surrounds Lake Tazawa is the question of what lies beneath its surface. For years, there have been rumors that a fortune in gold is hidden somewhere within its depths. According to legend, during World War II, the Japanese army dumped large amounts of gold bullion into the lake to keep it from falling into enemy hands. Several attempts have been made to locate the gold, but so far, nothing has been found. Some speculate that the Japanese government continues to search for the lost treasure, but the truth remains unknown.


Whether you believe in the legends or not, Lake Tazawa remains a fascinating destination that attracts visitors from all over the world. With its beautiful scenery, hot springs, and mysterious history, it is a must-visit location for anyone traveling to Japan.
