Companies catering to people suffering from sleeplessness are now in vogue as Japan goes through "the era of insomnia."

Panasonic Electric Works Co. is offering the Restino, a device that automatically controls light and sound factors to determine whether a person can be healed and can wake up fully refreshed.

Designed to create the ideal sleeping environment, the product helps a person fall asleep smoothly and wake with the aid of lighting and a speaker incorporated into the bed.
