The cost of hosting last year's Tokyo Olympics and Paralympics is now being set at ¥1.42 trillion ($10.5 billion), down ¥30 billion from the amount forecast in December, a source with knowledge of the matter has said.

The games' organizing committee will announce the official figure following its Tuesday board meeting, with the Tokyo Metropolitan Government's burden lightened by ¥20 billion following "close examination" of the costs, the source said Saturday.

The organizers, the metropolitan government and the central government were to jointly shoulder the games' financial burden.

In December's estimate, the organizers were to pay ¥634 billion, the metropolitan government ¥625 billion and the central government ¥194 billion.

The games were postponed for a year from the summer of 2020 due to the COVID-19 pandemic and spectators barred from most venues, depriving organizers of most of the expected ticket revenue.

December's estimate put the metropolitan government's share of the costs for additional safety measures at ¥62.8 billion. That figure will be reduced to around ¥40 billion.

The organizing committee is set to be dissolved at the end of this month.
