Rice prices have doubled in the last year, partly due to supply shortages and a surge in tourists

An earlier version of this story had the incorrect percentage in the headline, this has now been corrected.

More than 90 per cent of low-income households in Japan are struggling to afford food for their children due to surging prices and stagnant wages, according to a new survey.

The report published last week by international NGO Save The Children also shows that around 60 per cent of these households have reduced or stopped buying staple items, such as rice, due to high costs.

The June survey covered 7,850 households – including about 14,000 children – with monthly incomes of 112,200 yen (US$758) for a family of two, typically a single parent and child, and 151,000 yen for a family of four.
