Japan sees earliest cherry blossom since 1400s – and scientists say it’s down to climate change

The Japanese blooms usually take place in April, but arrived in March this year – the earliest blossom in 1,200 years.

Climate change has led to the earliest cherry blossom season in Japan in 1,200 years, experts say.

Traditionally, cherry blossom season starts in early to mid-April with residents in Kyoto holding “hanami” celebrations underneath trees to watch the flowers bloom.

Between 1971 and 2000, this specific type of tree was found to bloom on average a week earlier than all previous averages recorded in Kyoto – so 2021’s bloom is the result of a long-standing trend.

“Evidence, like the timing of cherry blossoms, is one of the historical ‘proxy’ measurements that scientists look at to reconstruct past climate,” climate scientist Michael Mann told The Washington Post.

“In this case, that ‘proxy’ is telling us something that quantitative, rigorous long-term climate reconstructions have already told us – that the human-caused warming of the planet we’re witnessing today is unprecedented going back millennia.”

Scientists have tracked the Japanese cherry blossom 732 times since the year 821, the longest and most complete seasonal record.

While flowers on the cherry tree bloom across the world, they hold cultural and historical significance in Japan.

In ancient Japan, farmers used the bloom to know it was time to plan rice crops and now the bloom represents hope, spring, beauty and new life.

Such is the significance of the cherry blossom in Japan, the mascot for the 2021 Olympics in Tokyo is inspired by the cherry blossoms.

While parts of Japan are seeing a premature blossom, in Hiroshima, Osaka and Niigata, yellow dust has been seen again instead.

The Japan Meteorological Agency says the seasonal yellow dust will arrive and reduce visibility by 10km.

Yellow dust affects large parts of East Asia during the spring months, caused by high-speed surface winds in China, Mongolia and Kazakhstan carrying soil over South Korea, Japan, China and North Korea.
