Although it is possible to teach English in Japan without a degree, it may be more challenging to find employment and you may have to accept a lower salary. Here are the steps you can follow to teach English in Japan without a degree:

- Get a teaching certification: One way to make yourself a more competitive job candidate is to obtain a teaching certification, such as a TEFL (Teaching English as a Foreign Language) or TESOL (Teaching English to Speakers of Other Languages) certificate. These programs can be completed online or in person and provide training on teaching methodology and language skills.
- Research job opportunities: Look for job openings at English language schools, private tutoring agencies, or through the Japan Exchange and Teaching (JET) Program.
- Apply for a work visa: If you are not a citizen of Japan, you will need to obtain a work visa in order to legally work in the country. You can apply for a work visa through the Japanese embassy or consulate in your home country.
- Prepare for the job search: Tailor your resume and cover letter to the requirements of teaching jobs in Japan and be prepared to showcase your teaching skills and experience during the interview process.
- Network and seek out recommendations: Building relationships with people in the English teaching industry in Japan can help you find job opportunities and get your foot in the door.
Remember that while it is possible to teach English in Japan without a degree, you may have to work harder to find employment and may have to accept a lower salary. It may also be more challenging to advance in your career without a degree.
