Toyota, Toyota Industries and Aisin will sell Denso shares worth a total of about 700 billion yen ($4.7 billion) at current market prices, the two sources said.
In a statement, Denso said it was considering a share sale, a buyback and other capital measures, but that nothing had yet been decided.
At $4.7 billion, it would be the second-biggest such share offering in Japan this year, after the more than $9 billion sale of shares in Japan Post Bank (7182.T) in March, according to LSEG data.
Denso shares, which were down almost 4% before the news, extended losses after the Reuters report and fell as much as 6.8% on the day, closing 4.9% lower.
Toyota shares finished little changed, as did the benchmark Nikkei 225 (.N225).
