Parents pay up to £70 for the privilege of having their child take part

For most parents the harrowing sound of a baby crying is one they could probably do without.

But for competitors at the 400-year-old Naki Zumo festival in Japan, the more sobs your little one can muster, the better.

During the bizarre festival, sumo wrestlers hold babies in the air to see which one cries the loudest and for the longest amount of time.

If the youngsters fail to cry the referee enters the arena and attempts to scare them into it by wearing traditional masks and making loud noises.

The ritual is said to be cathartic for the babies – bringing good health to those who take part as well as warding off evil spirits.

The annual festival, which has been held at various temples and shrines for the past four centuries, took place at the Kamitori Maekawa shrine in Yokohama.

It coincides with Japan's 'Children Day’ and parents pay up to £70 for the privilege of having their child participate.

After the ritual they are held to the crowd before being returned to their parents looking sorrowful and blotchy-faced.
