You do not mind refraining from enrollment this year. As I described earlier, I respect your decision.
I regret the result might dissapoint you.
I believe neither you are poor in ability nor in achievement. Thus you never be negative on your ability. I still believe you have high potential.
We have not been able to say anything about financial supports like scholarship, tuition waiver etc. , because those are highly competitive and anyone cannot expect confidently. The scholarship you had willing is recently giving priority to Double Degree Program students. Even for me, that is the glass ceiling.
I agree and am happy with your challenge to the MEXT scholarship through Shizuoika University. However we are at risk caused of the glass ceiling described above.
I draw your eyes on the following web-page;

Once you get a PhD student of Shizuoka University, I suppose you can apply to MEXT scholarship for international students already staying in Japan, company financial supports, etc.
