Morning all, and welcome to live updates from free practice one of the Japanese Grand Prix!

We'll be back at 6am UK time for the second practice session - just us then for that one!

So the drivers in order after that session: Button, Hiamilton, Vettel, Alonso, Webber, Alguersuari, Massa, Buemi, Schumacher, Petrov.

Vettel watches on as the stewards recover his car. Meanwhile the racers are doing a few practice starts to round off the session.

In the meantime, Jenson Button shaved 0.014 seconds off his best time.

Vettel went wide in Degner one, got on to the gravel and couldn't help but go into the tyre wall at the next corner. Front wing broken, but other than that it doesn't look too devastating. Drama nonetheless, though.

Session over - and as it comes, Vettel crashes!

Only time for a maximum of one more lap - will we see any improved times in this session?

Kobayashi inching along in his Sauber - bit disconcerting with that many cars out on track.

Limited tyre allocations for the drivers mean that most racers are on old rubber - the medium tyres unlikely to get any better this late in the session.

Glock has had a miserable morning for Virgin, with the car sidelined for most of the session with gearbox troubles. But good news for the German - he's going to get a couple of laps before the 90 minutes is up.

All the top six drivers out on track in the final five minutes of the session.

Vettel unable to make any improvement on his best time so far this morning - but it's so often around this time in a session that the German has popped up with the day's best time.

Several racers coming out for a final tilt in this session, including Button, who has the leading time.

Vettel follows Webber out - and this will be the pair's third run of the morning session.

Into the final ten minutes - will there be any late twists? Webber is out on track, Alonso back in the garage.

Rosberg seems to have spent plenty of time on track for very little result. He's still languishing, relatively speaking, in 16th place in the Mercedes.

A word on Senna - the Renault man is as happy as can be at the moment after getting the opportunity to race again.

Alonso still lapping, currently about a second off his best time. Back down to a handful of cars still on the circuit at present.

Vettel dives back into the pits after easing off considerably in the final lap of a seven-lap stretch.

Perez goes a little too late into the first corner of the chicane at the end of the lap, and has to run off track for the second corner.
