As Tokyo residents gear up to vote in Sunday's gubernatorial election, candidates are making last-ditch bids for ballots.

But while many voters hope to choose an individual whose platform meets their expectations, few candidates have said clearly how they would improve Tokyo — and are largely silent on who would pay for it.

The three front-runners — Yuriko Koike, Hiroya Masuda and Shuntaro Torigoe — are well aware of the issues Tokyo needs to address. They have all vowed to bolster the capital's disaster preparedness and to resolve the chronic shortage of day care centers, including by boosting the number of workers at facilities for the elderly.
