Do you need some musical cats to brighten your day? Never fear, Japan has just the thing.

The annual Tokyo Toy Show, which runs until Sunday, brings together 160 firms from all over the world to showcase the best they have to offer to an expected 160,000 visitors.

Toy makers in rapidly-aging Japan long ago branched out from targeting children only to aiming also at adults.

One such example of this superannuation strategy is "Licca-chan" - Japan's homegrown version of Barbie - whose maker Takara Tomy now produces a much-in-demand adult version.

Masayoshi Goto, a spokesman for Takara Tomy A.R.T.S, proudly showed off his company's set of musical felines.

"When you press the back of these cats, they meow in a scale, so you can play music with them," he proudly explained.
