Why is Mercari stock sliding today?

Mercari (4385) stock fell 5.4% to ¥3,658 after banning Pokemon 30th anniversary products to prevent disputes and harassment. The ban targets scalpers but may reduce transaction volumes. Broader tech and Japanese stock downturns also contributed, ahead of a Bank of Japan rate decision.
