The Japan Toy Association presented its first annual awards Tuesday, honoring five products including Bandai Co.'s popular bubble wrap toy named Mugen Putiputi.
Bandai's Mugen ni Dekiru ("able to do infinitely") series received the Trendy Toy award for uniqueness and wide acceptance.
Since its debut in fall 2007, the company has sold more than 2.3 million Mugen Putiputi key chains, which allow people to pop or snap plastic air bubbles endlessly ("putiputi" is Japanese for "pop pop").
