According to Reuters on March 5, Japanese chip manufacturer Kioxia (285A.T) and retailer Pan Pacific International Holdings (7532.T), which owns major discount store Don Quijote, will be included in the Nikkei 225 Index (.N225) starting April.

Meanwhile, battery manufacturer GS Yuasa (6674.T) and calculator maker Casio Computer (6952.T) will be removed.

Kioxia and Pan Pacific International are expected to boost this key benchmark index, which reached a record high in February 2026, but the momentum has been affected by the escalation of conflicts in the Middle East.

Since going public in December 2024, Kioxia’s stock price has increased more than 12 times. In 2025, Kioxia’s stock surged 540%, making it the best-performing stock in developed markets on the MSCI Global Index and the annual champion stock of the Tokyo Stock Exchange’s Topix Index. Its market capitalization once exceeded 5.7 trillion yen (about $36 billion), with the stock price reaching nearly 10 times the IPO price. Pan Pacific International’s stock price has risen 9.8% so far this year.
