U.S. Ambassador John Roos will visit the Nagasaki Atomic Bomb Museum and other places in the city Sept. 26, the Nagasaki Municipal Government said Friday.

Roos attended a ceremony Aug. 6 to mark the 65th anniversary of the U.S. atomic bombing of Hiroshima, becoming the first U.S. representative to do so, but he didn't attend the Aug. 9 memorial service in Nagasaki, citing scheduling conflicts.

The U.S. Embassy said later that Roos made a phone call to Nagasaki Mayor Tomihisa Taue before the service and expressed his hope of visiting the city in the future.

Meanwhile, Roos on Friday tried out a high-speed maglev train on the test track of Central Japan Railway Co. (JR Tokai) in Yamanashi Prefecture.

JR Tokai is aiming to sell the train to the U.S.

"I was amazed," Roos said after riding the four-car maglev for 57 km at a maximum speed of 502 kph, adding that the technology is "something that is going to change the lives of people."

The U.S. is placing "high priority" on high-speed railways and there is "big interest" in Japan's technologies, Roos said.

"Seeing is believing," JR Tokai Chairman Yoshiyuki Kasai said. "I think we were able to have him experience firsthand the potential of linear motors."
