Help my friend – Place to Rent

Hello kind people of Reddit,
A friend or mine lives in Tokyo with her husband. Their first baby is expected in February so they are looking for a slightly bigger place to live. The problem is that they found several houses, but every time they are denied because they are foreigners (indian). I was wondering if the kind people of reddit would have any tips or ideas to help them out.
