Meitoku Yagi began developing a series of kata in the 1970s and 1980s, which he named Meibuken kata. The first of which is Tenchi, meaning "heaven and earth." It was originally two kata, Fukyu kata ichi and Fukyu kata ni. The two kata can be put together so that if two karateka were to perform each half an attack in the first kata would correspond with a block in the second, for example. The Meibuken kata are different from the kata in the Goju-ryu syllabus in many ways, including having vertical closed hand chambers, and having a different yoi position, reflecting Yagi Sensei's Chinese roots, and his time spent studying martial arts there.
