SoftBank Corp. said Wednesday its Pepper humanoid robots will staff a cellphone store in Tokyo for a week this spring.

The firm said the static, talking machines will run the store from March 28 to April 3 in the city's upscale Omotesando shopping district. SoftBank already operates a separate store in the neighborhood.

"I don't know how this will turn out, but it should be a quite interesting experiment," said SoftBank CEO Ken Miyauchi during a two-day exhibition called Pepper World.
