Watch: Record rainfall causes flooding in Japan’s Chiba region

At least eight people have died as record rainfall pummelled eastern Japan and left thousands stranded at Tokyo's Narita Airport.

The rains, which authorities have described as "unprecedented", cut power to more than 20,000 households in Chiba prefecture.

Local authorities issued a level five emergency warning, its highest alert, on Thursday. This was downgraded to a level four by Friday morning, but they continue to warn of landslide and flooding risks.
