Meet Chihira Junco, the Robot greeting tourists in a Tokyo shopping mall

Meet Chihira Junco, a tourist greeter at a shopping mall in Tokyo. In her crisp blue button-down shirt, white blazer and pinstripe skirt, she stands in sensible pumps behind a counter in Aqua City Odaiba on Tokyo Bay, dispensing directions to local sites and shops in Japanese, Chinese and English.

She is not, however, human. Ms. Junco - if you can use an honorific for a machine - joins an incipient group of androids springing up around Japan. There are also Yumeko, a receptionist at the Hen-na Hotel, a robot-operated boutique in Nagasaki, and Matsukoloid, who appears in a popular television variety show with her human doppelganger, Matsuko Deluxe.

Toshiba, the electronics company, developed Chihira Junco in collaboration with technology labs at several Japanese universities. She and four other androids cost 10 million yen (over $A128,000) to produce, but only Ms. Junco is currently out in public, while the others remain with their maker. The company said it planned to develop 1000 more androids in 2017. By 2020, it hopes to make 10,000 a year.

At Aqua City, which is popular with tourists and where a small replica of the Statue of Liberty stands in a park near the mall entrance, visitors can tap on a screen to ask Chihira questions like "Where are you from?" ("I was born in Mizuho-machi, Nishitama-gun in Tokyo. I now live alone in the Minato ward") and "What's your favourite food?" ("I especially like watermelons and Japanese pears").

Up close, Chihara's robotic arm movements give her away, as do her eyes, which blink only halfway. When she "talks," she looks more like someone chewing gum than speaking. During a recent rendition of "My Heart Will Go On," from the movie "Titanic," her mouth barely moved and her gestures suggested a crossing guard directing traffic.

For those visitors who still long for genuine human contact, two actual human greeters stand at an information counter about 20 feet away.
