BOSTON (AP) — U.S. Rep. Niki Tsongas is heading to Japan as part of a bipartisan congressional delegation.

The Lowell Democrat and other representatives are scheduled to meet with officials in Tokyo and Okinawa including Japanese Prime Minister Shinzo Abe.

Tsongas says she hopes to discuss partnerships between local companies and Japanese businesses, the U.S.-Japanese security alliance and the prospect for American companies to grow overseas.

Tsongas says Massachusetts exported almost $2 billion worth of commodities to Japan in 2014, making Japan the fifth-largest importer of Massachusetts-made goods and services.

She says there are more than a dozen Japanese-owned businesses located in the state's 3rd Congressional District, which she represents.

Tsongas lived on an American Air Force Base in Japan as a teenager.

She is set to leave Saturday for the weeklong trip.
