A novel concept of a high luminosity hadron collider is proposed. This would be a typical application of an induction synchrotron being newly developed. Extremely long bunches, referred to as superbunches, are generated by a multi- bunch stacking method employing barrier buckets at the injection into the collider, and are accelerated to the collider energy with an step-voltage induced in the induction gaps. Superbunches intersect with each other, yielding a luminosity of more than $10^{35} /cm^2/sec$. A combination of vertical crossing and horizontal crossing can be used in order to avoid any significant beam-beam tune shift.
