Japanese Prime Minister Junichiro Koizumi heads south this morning for the great highlight of his trip: his first visit to Graceland.

"We understand that he is genuinely excited about

coming," said spokesman Todd Morgan. "It can be a very moving experience."

Koizumi, accompanied by George and Laura Bush , will arrive at the mansion shortly after 10 a.m., the first time it has ever been shut down for a private tour since it opened to the public in 1982. Then again, it's the first time a sitting president has visited the music mecca. "We've certainly had our share of celebrity visitors, but these are the two highest-profile leaders who have ever visited Graceland," Morgan said.

The presidential party will be met by Priscilla Presley and Lisa Marie Presley and will spend about two hours going through the house and the trophy building. The ropes are coming down for this special visit, so Bush or Koizumi can walk where Elvis walked, sit where Elvis sat . . . and play where Elvis played.

Koizumi arrived in Washington on Wednesday and stopped traffic that night at the Prime Rib restaurant. The party of 12, including Japan's ambassador to the U.S., Ryozo Kato , all had prime rib, lobster bisque and cabernet sauvignon. "I want to thank you for opening your markets to U.S. beef," Bush said at the joint news conference yesterday. "I think the Japanese people are going to like the taste of U.S. beef. As a matter of fact, I had a good slice of beef last night, and you told me you did, as well, and you look like you're feeling pretty good."

More beef at the White House dinner last night -- but today it's time for Elvis food. The tour will be followed by a lunch at the Rendezvous -- no word on the menu, but our money is on fried peanut butter and banana sandwiches.

Seller: Morgan O'Brien

Asking Price : $29.5 million

Details: The founder of Nextel and his wife, Belle , are unloading their 44-acre Wye River estate, Penderyn, named after a village in Wales. The 22,500-square-foot Georgian-style mansion (23 rooms, including 9 bedrooms and 9 baths) boasts a 60-foot gallery, 11 fireplaces with imported antique fronts, a swimming pool and six separate waterfront parcels near St. Michaels, Md. (If waterfront isn't your thing, you can buy just the residence for a mere $19.5 million.) The O'Briens bought the place for $8 million in 1999, then expanded and improved it. No word why they're downsizing, but the O'Briens still have a home in the District, a new villa in St. Maarten and a 110-foot yacht named Summer Love.

You got a problem with the way the Nationals are playing? Tell it to the team boss. His picture's right here.

At a luncheon of business execs yesterday at the Ritz-Carlton Tysons Corner, incoming Nats president Stan Kasten said he'll be found at almost every game, walking around. "I don't sit," he said at the Potomac Officers Club gathering. "I'm talking to fans. This is what I do." So a fan could complain about anything? "Guaranteed," he said.

During a Q&A session, the man who ran three Atlanta pro teams at the same time deftly sidestepped queries about getting games on TV and getting the D.C. Council to play ball. Steroids in baseball? Not going there. But, noting the presence in the room of former representative Tom McMillen (D-Md.), one of his Hawks players way back when, Kasten quipped, "Believe me, Tommy was never suspected of using steroids."

Alonzo Mourning driving through Georgetown on Wednesday in a green Range Rover, dressed post-workout-style in a tank top. Turns out the Miami Heat center and former Hoya was in town to pick up 9-year-old son Trey from a week-long basketball camp at GU -- there was a "Welcome Alonzo" banner waiting for him on campus yesterday.
