For a moment, I wonder if I¡¯ve accidentally strayed onto the set of a children¡¯s TV programme. Center stage are three grown men in matching T-shirts singing at the top of their voices in a Technicolor-bright toy-filled room more dazzling than Joseph¡¯s dreamcoat.

Beneath a sparkly disco ball, one man is strumming a guitar, another is pounding a keyboard and a third is energetically painting a rainbow onto a white wall with a dripping brush.

And in the middle of it all? Not an NHK camera crew ¡ª but my frowning 1-year-old Kiko Blossom, who is sitting on the floor in frozen wonder attempting to absorb the sensory overload around her.
