What is the monthly magazine "Mu"?

Since its launch in October 1979, this super mystery magazine has continued publication under the theme of "challenging the mysteries and wonders of the world," reaching its 550th issue in August 2026. Its themes cover all kinds of "suspicious things."
We continue to introduce topics such as UFOs, cryptids, ancient civilizations, parascience, psychic abilities, conspiracy theories, and spirituality, offering insights that are a step ahead of the mainstream, or even revealing the hidden aspects of society, from our unique perspective and hypotheses.
