In Japan, there appears to have been what probably constituted a long-held 'official' company bias against use of the name "Datsun". At the time, Kawamata was a veteran of Nissan, in the last year of his presidency, a powerful figure whose experience in the firm exceeded two decades. His rise to its leadership position occurred in 1957 in part because of his handling of the critical Nissan workers' strike that began May 25, 1953, and ran for 100 days. During his tenure as president, Kawamata stated that he "regretted that his company did not imprint its corporate name on cars, the way Toyota does. 'Looking back, we wish we had started using Nissan on all of our cars,' he says. 'But Datsun was a pet name for the cars when we started exporting.'"
