Tomy Co. and Adeka Corp. have renewed their recall of a microwave-heated "yutanpo" foot warmer in the wake of burn injuries.
Tomy and Adeka will return the purchase cost, including the consumption tax, to users who send the products back, the two firms said Monday.
Subject to the recall is an Adeka-made polyethylene-glycol agent that stores heat when placed in a microwave oven. If overheated, the plastic cover of the agent can break and spread a hot liquid.
Tomy has sold stuffed Hello Kitty toys containing the agent.
The products are used to warm people's feet in bed.
Although Tomy stopped selling the products in 2000 and began recalling them, burn injuries have continued. In the latest case, an elderly woman in Nagano Prefecture suffered burns in July and was hospitalized for a month.
