COE, do you believe that this will suffice?

I'll be visiting Japan for half a year for my studies, and I'm really looking forward to it! However, there is one issue: I only have around 200000 yen in savings and I'm worried that this will cause troubles with regards to the COE application.

Now, I'll have two supporters, my father and my uncle. Together they will give me around 100000 yen a month and I will also receive 100000+ yen a month as support from the government. So I have 200000 yen a month and perhaps I'll receive a scholarship of 100000 yen a month, but that has not been decided yet.

My dad and uncle are both retired and get a pension of around 500000 to 600000 yen a month each, as they were holding relatively high positions when they were still working.

My dad savings are not that high (perhaps ~3.5 million yen) but my uncle has around ~15 million yen in savings.

So to summarize: My savings are almost non-existent and I will have 200000 yen per month. But my supporters have almost 20 million yen in savings. Does this suffice, or might this still cause issues? I'm not sure about the importance of your supporters savings in comparison to your own savings.
