A lot of country making films in English, but in Japan we are very shy to speak English.

This is a good thing, mixing culture to make something new, something no one has ever seen. This is kind of a new history.

Keanu Reeves learned a lot, respecting the culture. I was surprised when I first met him. He knew a lot already and he learned a lot. And also he learned Japanese. It's incredible. On the set, switching between the Japanese and English, even for us, is very hard. It's complicated. But the first time Keanu spoke in Japanese it was a very important scene between us, and more than the dialogue's meaning, I was moved. His energy for the film, completely perfect Japanese pronunciation. It was moving, surprising, respecting.

It's a Samurai story [47 ronin], so if we change too much Japanese audiences will have strong against feelings to the film. It's not good.

It was a black and white film [at first]. And then it changed to colour film, and I was surprised and culture shocked when I was six or seven years old. And then HD, then 3D now. So what's going? What's coming next? It's so exciting.

I was a child actor, so when I started filming when I was five years old, it was a long time ago.

When I was eight or nine years old, I saw the TV version of 47 Ronin, played by Toshiro Mifune. He played Oishi. That was my first experience. I watched every week with my brother. "Who plays Oishi tonight? Who will play Kira tonight?" And we fought every week.
