Embattled Tokyo Gov. Yoichi Masuzoe is likely to be forced to step down after the ruling coalition in the metropolitan assembly threatened to submit a no-confidence motion against him on Wednesday.

The assembly's ruling camp, comprising the Liberal Democratic Party and Komeito, agreed Tuesday that Masuzoe should resign over the use of some ¥4.4 million in taxpayer funds for private purposes.

If a no-confidence motion is passed, Masuzoe will be forced to choose from two options: step down or dissolve the assembly for a snap election within 10 days.
