Eyewear-maker Jin Co., which offers low-price glasses under the brand name Jins, aims to expand its business overseas amid a shrinking domestic market, CEO Hitoshi Tanaka said Friday.

"Japan's market will be shrinking because of low birthrate and aging population. This is why we started going overseas at an early time and are looking at the global market, although this is rare for (Japanese) eyewear makers," said Tanaka at the Foreign Correspondents' Club of Japan in Tokyo.

Jin, which had 292 stores in Japan as of November, entered the Chinese market in 2010 and now has 60 stores there. The firm opened its first U.S. store in San Francisco in August and is looking to enter other regions such as Europe.
