HANOI, July 9 (Reuters) - Uruguay-born Sebastian Quintana fired a dramatic late equaliser to earn Qatar a 1-1 draw against holders Japan in their Asian Cup opener on Monday.

Naohiro Takahara's close-range strike after 61 minutes had

looked good enough for Japan until Quintana's deflected free

kick flew into the top corner in the 88th minute.

'We were careless!' Japan coach Ivica Osim fumed after his

side's failure to kill off the game. 'This result could make it

difficult for us. The players have got to learn to turn style

into substance.'

Eintracht Frankfurt striker Takahara clinically tucked in

Yasuyuki Konno's flicked cross with a left-foot volley for his

20th goal in 48 internationals.

But Japan were undone after Yuki Abe's clumsy foul on

Quintana, who blasted the subsequent free kick past Yoshikatsu

Kawaguchi from 25 metres with the help of a deflection.

Japan, bidding for a third straight Asian Cup title, trail

Vietnam in Group B after the co-hosts' 2-0 win over United Arab

Emirates at the weekend.

Even a red card shown in stoppage time to Hussain Yaser

failed to dampen the joy of Qatar coach Dzemaludin Musovic, who

was also ordered down the tunnel for protesting the decision.

'Of course Japan won't be happy with the result,' said

Musovic, who was assistant to Osim when he led Yugoslavia to

the quarter-finals of the 1990 World Cup.

'But we deserved to take a point and I think we can be a

danger to any team in the tournament now.'

Yaser will be banned for Qatar's game against Vietnam on

Thursday while Musovic could also face sanction pending an AFC

disciplinary meeting.

Japan playmaker Shunsuke Nakamura said Qatar's last-gasp

equaliser had shocked the holders, who never really hit their

stride in Hanoi's clinging humidity.

'We were in control and then it was just a sense of 'ugh!'

when they scored,' Nakamura told Reuters.

'We need to learn to finish the game off with a second

goal.'

The Celtic midfielder added: 'Abe feels gutted right now

after the foul but we'll bounce back.'

Japan face UAE in their second game on Friday.

This year's tournament is being staged jointly by Vietnam,

Indonesia, Malaysia and Thailand. The final is in Jakarta on

July 29.
