Shareholders of Takata Corp. expressed disappointment and anger Tuesday over how the air bag maker¡¯s top management has handled its product safety fiasco.

Hiroshige Kono, 75, of Kawasaki, who came to a shareholders meeting in Tokyo the day after the company filed for bankruptcy protection under the Civil Rehabilitation Law, said it was a ¡°mistake¡± for him to have invested in Takata.

¡°I thought Takata would be OK as it is one of the top-three global air bag makers. I thought the company would never fall,¡± said Kono, who bought shares in Takata three years ago. ¡°I¡¯m ashamed of having Takata stock out of my greed. I now feel frustrated with myself.¡±
