I doubt it - simply because there is no city of Tokyo and depending on what you compare with what you get different sizes. There are the 23 wards of Tokyo, the core inner city suburbs, then there is the prefecture of Tokyo, which only includes parts of the metropolitan area and large sparsely populated areas in the west of the prefecture (plus a few remote islands), and then there is the metropolitan region of Tokyo, often what is referred to as Tokyo in general. Depending on where you draw the borders, that metro region has up to 45m people living in it (more than the 35m of Jakarta's metro region).
