Oscar Piastri surprisingly led the way after a heavily rain disrupted FP2 session saw very little running at the Japanese Grand Prix.
An eerie silence covered the Suzuka circuit for 80% of the second practice session before some drivers decided to tiptoe around the track towards the end of the hour.
Lewis Hamilton continued an impressive recovery from a poor start to the season, placing inside the top four for a second consecutive session in Japan.
Despite a purple sector, he failed to beat Oscar Piastri by five tenths as he ended up in second place but placing in the top two is better than Mercedes have come close to showing in any of the three grands prix so far this season.
Stop-start rain frustrated the pit-lane for a while, with a tricky median between wet and dry running making it too risky for most teams to do any meaningful running - and therefore making Saturday's FP3 session all the more important.
Red Bull responded to their poor result last time out in Melbourne in immediate fashion by topping the first practice session of the Japanese Grand Prix with a one-two finish at the top of the pack.
Spurred on by some new upgrades, Max Verstappen led team-mate Sergio Perez by two tenths, with Carlos Sainz clipping their heels in third place after nearly matching his Mexican rival.
Mercedes started the weekend on the right foot after a devastating double DNF last time out, with George Russell and Lewis Hamilton both inside the top five at a track which their drivers love to go well on.
Hamilton - whose engine suffered a catastrophic failure, which cannot be fixed at the Australian Grand Prix, is using a new power unit in Suzuka which fired him to fifth place in a big improvement for the Silver Arrows in the early showing.
Home favourite Yuki Tsunoda ended the session in ninth place for Visa Cash App RB while fellow countryman and FP1 debutant Ayumu Iwasa finished in 16th place.
McLaren appear to be waiting to deploy their pace, after Oscar Piastri ended the session in eighth ahead of Lando Norris in tenth.
