TOKYO — With the dolphin flap over and done with, Olivia Newton-John can get on with the business of doing what she does best — singing.

In March, the self-professed animal lover canceled her third concert tour here when she discovered Japanese fishermen were killing dolphins they said were hurting their livelihood.

"I was upset about the incident. I didn’t refuse to sing here, I merely canceled my tour because I was upset. It was an emotional decision," she told reporters Wednesday.

She is back in Japan after discovering research has begun on how man and dolphin could live together peacefully.

The International Marine Biological Institute is studying the intelligent creatures and Miss Newton-John is donating $20,000 from this tour toward the research.

It has been two years too many since the pretty blue-eyed blonde has graced Japan stages.

Since then, she has proven herself not only an above average animal lover, but a capable actress as well with her performance in "Grease."

The movie has already opened in military theaters, but isn’t scheduled to premier on the Japanese circuit until November.

Miss Newton-John, 30, plays the part of an 18-year-old high school student, a part Marie Osmond said she turned down because of the sometimes raunchy goings on in the flick.

But the Image doesn’t bother Miss Newton-John.

"I think it suits me perfectly," she said.

"I get to play two roles. In the first half of the movie I play the kind of person most people think of me as. But, near the end, I play what I think is another side of me."

That other side, shown off in skin-tight black pedal pushers and wild hairstyle, is indeed anything but the pure and wholesome image which surrounds the Australian-born singer.

Despite her protests and budding movie career, however, Miss Newton-John appears most at home singing.

And sing she did in Tuesday’s opening performance at the Budokan.

After weaving through standards like "Let Me Be There," and "Have You Never Been Mellow?" she included two selections from "Grease" and her latest single, "A Little More Love."

And, amid cheers of "Olivia!" she proved that, protests be damned, they still love her.

For those who missed her first Tokyo performance, she’ll be back in Yokohama’s Bunka Cultural Hail Oct. 31 for a 6:30 p.m. final concert.

She’s also slated for a 6:30 p.m. performance Tuesday and 3:30 and 6:30 p.m. shows Wednesday in Osaka’s Festival Hall.
