TOKYO (Reuters) – Toyota Motor Corp (7203.T) plans to raise its stake in Subaru Corp (7270.T) to more than 20% from around 17% now, expanding their partnership to invest more effectively in new technologies, Nikkei reported on Friday.

The move is seen costing more than 70 billion yen ($650 million) based on Subaru’s stock market value, the Japanese business daily said, without citing sources. Subaru will spend the same amount to buy a stake of less than 1% in Toyota, it said.
