U.S. startups focusing on care products and services for the elderly are tapping into the graying Japanese market, where more than 35 million people are over the age of 65.

Seismic, a California-based apparel company, hopes to expand in Japan with its Powered Clothing, a body suit using robotics and sensor technology inside the garment to mimic human movements and increase strength.

The body suit is meant for all ages, but Seismic has found particular success with elderly people who enjoy sports and travel in the United States, where the population is also graying.
