Nintendo Co., Keyence Corp. and Murata Manufacturing Co. will join the 225-issue Nikkei average in a major change to the makeup of the blue-chip gauge.

The three companies’ stocks will be added on Oct. 1, Nikkei Inc. said in a statement. The long-awaited inclusion of Nintendo comes after Nikkei implemented changes to the way the measure is calculated, allowing for the adjustment of high-priced stocks.

Nisshinbo Holdings Inc., Toyo Seikan Group Holdings and Sky Perfect JSAT Holdings Inc. will be removed.
