Japan
In 1878, on Fleeming Jenkin's recommendation, Ewing was recruited to help the modernisation of Meiji Era Japan as one of the o-yatoi gaikokujin (hired foreigners). Serving as professor of mechanical engineering at the Tokyo Imperial University, he was instrumental in founding Japanese seismology.

Ewing made two special friends at Tokyo University soon after arriving: Basil Hall Chamberlain and Lieutenant Thomas Henry James R.N. who taught navigation. He was also in close contact with Henry Dyer and William Edward Ayrton at the Imperial College of Engineering (Kobu Dai Gakkō).

In Tokyo, Ewing taught courses on mechanics and on heat engines to engineering students, and on electricity and magnetism to students of physics. He carried out many research projects on magnetism and coined the word 'hysteresis'. His investigations into earthquakes led him to help T. Lomar Gray and John Milne of the Imperial College of Engineering to develop the first modern seismograph, from 1880–1895. All three men worked as a team on the invention and use of seismographs, though Milne is generally credited with the invention of the first modern horizontal-pendulum seismograph.

Ewing joined Gray and Milne in founding the Seismological Society of Japan (SSJ) in 1880.
