You have no college degree and are from the Philippines. No work visa for you.
No working holiday visa, either.
To get a work visa, you need either a college degree or many years of related job experience.

So, your options in order to work are as follows:
student visa (work PT with special permission)
cultural activities visa (work PT with special permission)
intracompany transfer visa (work FT, but you must have worked at least a year in your home country for the company that is willing to send you here to their branch office)
internship/trainee visa (little to no pay, short-term work)
If you can't meet the qualifications for those visas, then you would have to be married to a non-Japanese who has a proper visa so that you can get a dependent visa (and work PT), or you would have to be married to a Japanese to get a spouse visa (and be able to work FT, but only for employers who think you are qualified despite lacking a degree).
You're not in a good situation. Being sincere and desperate will not get you work legally here. IT work is hard to come by. If English is needed, J companies tend to hire Indians, BTW.
