On Craigslist this may be a long shot, but it is worth a try.
My visa recently expired and I am in the post-extension period. I am looking to stay in Japan and I am looking for a new company that can sponsor me.
The visa process would start from scratch but I could start very soon.
My main experience is in teaching and translation. For teaching - general conversation, business, IELTS, TOEIC, other testing and occasionally more specialized material. I am Japanese fluent and have also worked in translation for 7 years, working on mainly general fields such as business, marketing, tourism and entertainment.
Again kind of unlikely to find something like that here on short notice, but on the off chance you really are looking to fill a vacancy and can provide a visa, I can send you my English and Japanese resumes.
Note - if you are unable to do this and have remote / part time or freelance work, I would be open to that as well.
Live in the Kanto area.
