marriage and spouse visa

i am from India and my girl friend is living in Japan. we love each other last 7 years however she is elder than me. we both decided to marry, my family is not accepting to marry my GF. i dont wanna leave my GF and i decided to marry her and settle with her in Japan. my GF is accepted for my decision also.
I dont know about the formalities like where to marry and how to get visa and what type of visa i need to apply.
Hence i request you all to help me. thanks in advance

Worldismyhome,

Assuming your girlfriend is Japanese and you currently live in Japan, you will need to first contact your embassy in Japan to obtain a document that proves you are single and eligible to marry. You then need to take this to the city (or ward) office where you are currently registered and ask them what documents you need to submit to register your marriage.
Once you're married, you can then go to your nearest immigration office to apply for a spouse visa.

Thank u so much Dave,

Currently im living in India now and my GF is a permanent resident in Japan. at this kind of situation what kind of steps i needs to follow. Thanks again Dave

Worldismyhome,

If you intend to get married in Japan, then you will both need to contact the Indian embassy in Japan to obtain proof of eligibility to marry.
