B.Tech in Japan

Hello Harpreet, It's very nice to see your desire of studying Engineering graduation in Japan. However many countries including Japan do not accept Diploma as the qualification for undergraduate studies. 10 + 2 or XIIth standard is normally considered as the basis for granting admission. However some colleges do accept Diploma as equivalent to 12th and based on this assumption you can seek admission. In this connection my sincere advice to you will be to get in touch with an agency sending students to Japan for undergraduate studies since there are many nuances that are involved and even if you miss out on one, admission could be affected. It would be in your interest to go to such an agency. Best wishes.
