Konichiwa, gadget-san. And welcome to the temple of other-worldly delights, where one's objective is to say a few prayers, throw some sand around, bow now and again, and heave a 25-stone elephant of a man about while staying on one's feet...

Ah yes. There's nothing quite like a dose of Sumo to quicken the heart. Not even wrestling on World of Sport on a Saturday lunchtime came close. And, let's face it gentlemen, WWF is all theatre and no trousers (literally). So, for real men, in real, blubbery, sand-kicking action, one has to turn Japanese.

As it's difficult to create the authentic conditions required for sumo in, say, West Bromwich, we at Gadgetshop HQ have come to the rescue with the miniaturised plastic equivalent. You would expect no less of us, after all.

These two robo-sumos are remotely controlled for your pleasure, and, being remotely controlled, can go head-to-head at high speed, while you stand well back. Doing battle on a fold-out ring - cunning and dexterity, rather than brute force and ignorance, may well be the order of the day.

The sumos' gigantic feet could prove your most valuable weapons, as these plates of meat can be used to devastating effect - tripping, flipping and getting in all manner of inconvenient places.

Bow low in respect. And then let blubbery battle commence.
