Mt. Tsukuba is also known as the "Purple Peak" because the color of the mountain's surface changes several times a day - indigo in the morning, green in the afternoon, and purple in the evening.
Mt. Tsukuba has two peaks - Mt. Ottai and Mt. Ontai - and people have long revered the mountain as a symbol of production and a place where deities reside.
In Japan, Mt. Fuji shines in the west, and Mt. Tsukuba stands tall in the east. Together, the two mountains make for a wonderful topic upon which many poets have based their poems, including the authors of Japan's "Manyoshu" and "Ogura Hyakunin Isshu."
The mountain has been protected as a Shinto shrine for a long time, so when you are there, you will be able to find many rare plants, insects, and wild birds (such as the hoshizaki saxifrage, which has been selected as the city flower), making it a precious "treasure house of nature" in the Kanto Plain.
There are many ways to explore Mt. Tsukuba, from hiking to driving along the Tsukuba Skyline while enjoying its seasonal changes.
