Konkona Sen Sharma believes that "The Japanese Wife" is Rahul Bose's best film so far.

"I think this is Rahul's best film. This is a very poignant, sweet and sad love story. It's very unusual. This kind of film we don't get to see always, " said Konkona who worked with him in "Mr & Mrs Iyer".

"The Japanese Wife" is about three people - Snehamoy Chatterjee (Rahul Bose), an arithmetic teacher in a school in the interiors of West Bengal, his pen friend Miyage (Chigasu Takaku) and Sandhya (Raima Sen), a widow who takes refuge in his home.

"It's a funny film because there is a Bengali boy who is in love with a Japanese wife and neither of them speaks English. So the conversation is so funny. I think people will enjoy it. I hope so, " Konkona told IANS at the premiere of "The Japanese Wife" here Wednesday.

Asked if she expected her mother would select her in place of Raima, Konkona said: "I think that Raima has done a very good job. You can't expect that every time she (Aparna) will repeat same actors and same actresses. I have already done three films with her and am sure will do many more."

Eight years after Rituparno Ghosh's "Titli" (2002), Konkona will be seen with her mother once again in "Iti Mrinalini".

"My next film is 'Iti Mrinalini'. It's also mommy's film. That's about a life of an actress where both of us are acting together, " said Konkona.
