Kenji Kaido recently announced over Twitter that he has left Sony Computer Entertainment Japan's Product Development Department where he worked as a producer.

The translated tweet reads:

I have some news. This August, I left Sony Computer Entertainment. My plans for the future are undecided as of now, but for the time being I’m going to continue my summer vacation

Kaido produced the critically acclaimed Ico and Shadow of the Colossus but was not said to be involved in the troubled development of The Last Guardian.

Kaido's departure continues the worrying trend of high profile employees leaving Sony. Creative minds that have helped to create some of Sony's most respected titles over the past decade. In December of last year we had the news that Yoshifusa Hayama had left Sony to work for London-based social games developer Bossa Studios, in addition to the news that Fumito Ueda, director of Ico, Shadow of the Colossus and The Last Guardian was also leaving Sony but would remain part of the team on a contractual basis, in order to complete the development of The Last Guardian

What exactly is happening at Sony Computer Entertainment Japan? The company has definitely seen better days and its future continues to look bleak. It is a shame to see a company with so much creativity and talent, that has created some of the most memorable games of all time, struggle to maintain that level of success. Hopefully Sony are working to solve the internal issues that are clearly hampering the productivity of the developer, enabling the studio to return to the winning formula that brought it so much success in the past.
