Home Loan in Japan, as a disabled veteran

My wife and I are looking into purchasing a home in Japan, we have lived here for a couple of years and want to settle down as our dogs are getting too old to travel: Lucy, Golden Retriever (9) and Ghost, German Shepherd (5)

We have been trying to secure a loan through Tsumitomo Housing and a few other banks, but because I do not pay taxes on my disability income in Japan no bank is willing to consider it income for the basis of a loan.

We currently pay 210,000 Yen a month for rent right now, but our accommodations aren't fantastic considering finding a place that would allow 2 big dogs and foreigners was a very challenging experience and we don't really love the place we're staying now.

Our top end budget would be about 90 million yen, but most banks are only willing to loan about 60 million to my wife as a solo loan. Does anyone have any experience in trying to have disability income verified as income for a loan in Japan? Based on the US-Japan Pension Treaty, I am not required to pay Japanese taxes on my disability income.

Any help would be most appreciated
