Sinha, ranked more than 160 places below his Japanese rival, dropped the opening set before gathering his wits to carve out a shock 4-6 6-2 7-6(7) victory in the quarter finals.
Joining Sinha, a lowly 294 in the world junior rankings, in the last four were his compatriots - top seed Siddanth Banthia and Megh Bhargav Patel - and Malaysia's Christian Didier Chin who ousted India's seventh-seeded Dhruv Sunish.
Mahak Jain breezed past compatriot and wild card Salsa Aher 6-2 6-2 while Mihika also scored a easy win over Funa Kozaki of Japan 6-1 6-2 in today's quarter final ties.
