Tiago Monteiro led his new team-mate Takuya Izawa as Honda claimed a one-two in first World Touring Car Championship practice at Suzuka
The Portuguese driver hit the front from the outset, with his opening effort of 53.703s too good for the rest of the field.
With six minutes to run however he shaved an extra few hundredths off that time to end on a 53.683s, leaving him almost two tenths of a second clear at the top.
Izawa, a winner in Super GT this year, followed a similar pattern, with his opening effort enough to send him - and keep him - second overall.
Champion elect Yvan Muller was less than 0.1s down the road in third, while BMW man Tom Coronel prevailed in an extremely tight fight for fourth.
Norbert Michelisz, Pepe Oriola, James Thompson, Stefano D'Aste, Gabriele Tarquini and Rob Huff rounded out the top 10, with all six men finishing within four tenths of Coronel's time.
While there were no stoppages - in contrast to Friday's heavily interrupted test there were a multitude of incidents and moments throughout.
Muller, Huff and Michelisz were among several men to run off-track, while Masaki Kano drafted in to replace the ill Franz Engstler spun exiting Turn 8 and Marc Basseng slewed wildly into the gravel at Turn 2.
The latter ended the session down in 22nd, although still within 1.5s of pacesetter Monteiro.
Aside from Izawa, Hiroki Yoshimoto was best of the numerous newcomers, ending 11th fastest in the sole Nika Chevrolet.
