Keeping the tradition afloat... This is swimming samurai-style.

Mutsuo Koga shows off his skills in the Japanese city of Yokohama.

But once he's in the pool, it's sink or swim. The armour weighs 15 kilos.

The feared warriors developed this form of swimming around the 15th century. They had to brave waves and currents.

Nowadays, the most difficult part seems to be getting out of the pool.
