Kosuke Ota produced two free kick assists as FC Tokyo kept up its strong J. League form with a 2-0 win over defending champions Kawasaki Frontale on Saturday.

Tokyo, which went into the game at Todoroki Stadium in second place, took the lead when full-back Ota's pinpoint delivery found Kento Hashimoto in the 14th minute and was helped on its way by a mistake by Frontale goalkeeper Shota Arai.

The capital city side then used the same supply line to double its advantage in the 69th minute, as Ota picked out Masato Morishige to help Tokyo claim its eighth win in 10 league games.
