So a non-smoker in Japan who lives with a smoker has a 1.9 increased chance of getting lung cancer than she would have had she not lived with the smoker, that risk is readjusted to 1.3 when other factors (such as diet) are taken into account.

"Relative Risk
Definition: Relative risk is a measure of how much a particular risk factor (say cigarette smoking) influences the risk of a specified outcome (say, death by age 70)
For example, a relative risk of 2 associated with a risk factor means that persons with that risk factor have a 2 fold increased risk of having a specified outcome compared to persons without that risk factor."
Isn't a relative risk of 2 considered insignificant?
