Masi Oka is celebrating his 51st birthday today. As a number of online tributes attest, he is one of the most acclaimed actors of his generation.

Popular actor Masi Oka (Hawaii Five-0, Heroes, ...) has always liked to keep a bit of himself hidden from view. At 51st birthday, he remains a man of many facets.

Oka, a cultural icon

Born Masayori Oka in Tokyo on December 27, 1974, his career spans an arc over many different eras and tastes in American history. Oka's not just a great actor, he's an inspiration, an icon and a successful business man. At this point in his career, there seems to be little Masi hasn't done.

And we've got a feeling the next 12 months are going to be even bigger and better for Masi Oka as he promises more to come. After all, he's only 51.

Happy Birthday, Masi, you're the best!
