The Japanese, who won the under-23 world title last year and added this year's World Cup crown, proved her superiority yet again.
By the end of the first period, the Japanese with a takedown and a step-out led 3-1 and, in the second, retained her aggression to score four more points, both on take downs even as Ritu managed a couple of points for the take down and one through hold.
But with time running out on her, Ritu could not overcome the deficit.
However, Ritu had done herself proud by holding on to her nerves to overpower her Bulgarian rival Sofiya Hristova Georgieva 9-8 in the repechage round and enter the bronze playoff.
It was a pulsating bout in which Ritu led 3-1 by the end of the first period. But the Bulgarian fought well in the second through a four-point throw to go 5-3 up.
However, Ritu returned the compliment and won a four-pointer and a step-out point even as the Bulgarian came too close for the Indian's comfort as Ritu edged her rival out of contention.
Earlier, Japan's Yukako Kawai outclassed Olympic medallist Sakshi Malik 16-2 in the 62 kg quarterfinals. The twice World Cup title winner was technically superior to Sakshi as she had very little chance against her, despite leading 2-1 in the first period.
However, the Rio Games bronze medal winner entered the repechange round after Kawai had reached the final.
In 50kg category, after a rousing start by Ritu Phogat in the pre-quarterfinal against Thi Yuan Nguyen of Vietnam with a technical superiority, the Indian lost her quarterfinal bout by fall to Yui Susaki.
The last year's world champion in 48kg category won 11-0. Like Sakshi, Ritu too got luckier and entered the repechage round where she will meet Alina Emilia of Roumania on Thursday. The Japanese, who Ritu conquered her in the quarters, too entered the final.
Pinki (53kg) lost her quarterfinal to Poland's Katarzyna Krawczyk 2-7 while CWG silver medallist Pooja Dhanda lost 3-4 to China's Ningning Rong at the same stage in the 57kg.
Pooja should thank her quarterfinal opponent from China for giving her a lease of live in the repechage round as Rong entered the final, to be played on Thursday.
