On November 22, 2021, A Japanese court blocked Kansai Super Market's plan to merge with H2O Retailing Corp, OK Corporation issuing an injunction that raised questions about the validity of an earlier shareholder vote. Kobe District Court made the decision in response to a request from supermarket chain OK, which challenged the result of the shareholder vote. OK had been trying to acquire Kansai Super before H2O stepped in.
