Studies have shown that it's not reading to kids that encourages them to be avid readers, but having them watch you read and enjoy it. Read what YOU like, what interests you, and read it in Japanese! They live in an English speaking community. They're going to learn English no matter what because that's what their friends speak.
I read it in the Daily Breeze or L.A. Times, but this is what I was able to find in a few minutes online...
Basically, children will find reading enjoyable if that behavior has been modeled, same thing as why soccer moms have soccer kids, and surfing dads have surfing kids, because the kids were taught that those activities were enjoyable, (or over eating, or healthy eating, anything else that a family does on a regular basis.) If you hate reading and your kid picks up on it, just like fear of water, or a picky attitude about food, you won't have a kid who loves to read.

Kimball, who conducts research on reading and literature for children and youth, as well as library services for young people, points to research showing repeatedly that children who find reading a pleasure have a much easier time understanding and learning math, geography, history and every other academic subject. Non-readers, on the other hand, pay a very high price in terms of academic failure.
"Although some children have learning or behavioral problems, this is not true of all non-reading children." Kimball says. "It is more likely that no one has encouraged in them the simple enjoyment of reading, which is a very important parental job."

When children are provided age-appropriate books of their own, and when they see adults reading, they acquire important knowledge about the use and handling of books. For example, they learn the proper orientation for holding a book and that reading proceeds from front-to-back and left-to-right in books. Further, they learn that the print in books, rather than the pictures, carries the message. Finally, these activities also allow children to see that print corresponds to speech in fairly regular ways. This knowledge is essential if children are going to master the alphabetic nature of the English language. Each of these ideas is essential to skilled reading, yet they are facts that most adults take for granted (Goodman, 1986).

As parents and adults read with children at the library, they are also modeling positive behavior. Research suggests that if children see the adults around them reading, then they view reading as more valuable. Young people develop a feeling of accomplishment when they read a book on their own.
