Officials in Japan want businesses to be more transparent about how climate change could threaten their operations or earnings.
The Financial Services Agency says it will set up a panel of experts to look at various ideas in the coming months, including new regulations compelling firms to state the risks on their financial statements.
Some firms already volunteer details of climate threats that could affect investment decisions.
But not all business leaders in Japan want it to become mandatory. Some say it would be a heavy burden on companies.
Western countries have been leading the push for such disclosures.
An international framework called the Task Force on Climate-Related Financial Disclosures has been promoting the idea and laying out recommendations.
