Student Visa or Tourist visa

Greetings everyone! I have a Bachelor’s degree in Computer Science and worked in the field for one year before taking a two-year gap due to family problems, after which I pursued a Master’s degree in the same field(Computer science). I’m set to receive my certification in July, and while I have a job offer, I’m contemplating rejecting it because I don’t want to spend two to three years gaining experience before applying for jobs in Japan. My goal is to move to Japan as soon as possible and find employment directly there. I’m wondering if it’s possible to secure work in Japan through a Student Visa(language school) or tourist visa, or if there are other options available. If you have any insights or suggestions, I would greatly appreciate your advice.
