Is there anyone in Shizuoka who got the 特別免許状?

Hi, title explains it really.

I'm a direct hire ALT in Shizuoka prefecture looking to get the special teaching licence and would like to become a full-time JHS (public school) teacher from next April. I meet all the requirements as stated on the prefectural website and am fluent in both written and spoken Japanese, so no problems there. I am currently discussing the process with my local BOE (employer), but would like to be able to talk to someone who has already got the licence, and know of no-one in my area.

Is there anyone in Shizuoka prefecture who has gone through the process of acquiring the special licence, especially someone who was previously a public school ALT? I have some questions about the process of getting the licence and would just generally like to ask you about getting it, the job after getting it, etc. etc.

Would prefer to hear from/be able to DM people specifically in Shizuoka, as the process differs from prefecture to prefecture, I believe. But would also appreciate hearing from people with the licence working in public schools in any area. How was the process? How long did it take from start to finish? How involved was your school in the process? Or did it go through the BOE? Do you regret giving up the ALT life for a much harder job? Or do the rewards outweigh the increased workload? Any tips?

Thanks.
