TOKYO (November 26) -- Akari FUJINAMI (JPN) won't be defending her Olympic gold at women's 53kg at the 2028 Los Angeles. That's bad news for anyone aiming to strike gold at 57kg.

Fujinami has announced that she will move up to the next Olympic weight class starting next year, the Japan federation website and Japan media widely recently reported.

Fujinami, who turned 21 on November 11, cited the difficulty of cutting weight for the decision, as well as the historic aspect that no woman wrestler has ever won a second straight Olympic gold after moving to a higher weight class.

"I have decided to move up to the 57kg weight class," Fujinami said after Sunday's East Japan Collegiate Women's League, a team tournament that marked her first competition since winning the gold at the Paris Olympics in August. "Considering my height and my normal weight, I think I can give my best performance at 57."

Fujinami competed at 59kg in the five-team league tournament (one school was a no-show), which was run in a round-robin, duel-meet format with only three weight classes -- 53kg, 59kg and 76kg.

She won both of her matches by fall, extending her current winning streak to 139 matches dating back to her junior high school days in September 2017.

The 1.64-meter Fujinami was actually wrestling near her natural weight of 60kg. But even against two naturally bigger opponents -- Ikuei University's Ichika ARAI (JPN) was the 2023 world U20 silver medalist at 57kg -- her skills and speed were overwhelming.

"It has been really hard to cut down to 53kg," Fujinami said. "I felt I lost muscle during the process. I feel I can give my best performance by going down three kilos from my natural weight."

Asked when she expects to make her full-fledged "debut" at the new weight, she replied in a text message, "It will be sometime next year. I haven't decided exactly when yet."

With a full schedule of post-Olympic TV appearances and local events curtailing her training, she has already ruled out appearing at next month's Emperor's Cup All-Japan Championships.

It is likely she will compete at the Meiji Cup All-Japan Invitational Championships in the spring, as that tournament, along with the Emperor's Cup, will serve as qualifiers for the 2025 World Championships.

The move up to 57kg will likely put her on a collision course with the reigning Olympic champion, Tsugumi SAKURAI (JPN). The two met last year at the East Japan Collegiate tournament, with Fujinami coming away with a 5-0 victory.

The challenge of possibly accomplishing a historic first appeals to Fujinami, who last year won her second career world title at 53kg in Belgrade.

"I heard that no [woman] has moved up a weight class and won another Olympic gold," Fujinami said. "It will difficult, but that's what makes it challenging. I hope I can become stronger at the next [Olympics] in Los Angeles."

Two Japanese women -- Saori YOSHIDA (JPN) and Kaori ICHO (JPN) -- have won an additional Olympic gold after going down a weight, but that was mainly because the number of weight classes was expanded from four to six, allowing them to compete more closely to their normal weight.

Among men, the legendary Aleksandr MEDVED (URS) won the freestyle 97kg gold in 1964, then triumphed again at 97+kg in 1968, while Levan TEDASHVILI (URS) won at freestyle 82kg in 1972 and 90kg in 1976. More recently, Abdulrashid SADULAEV claimed the freestyle 86kg gold in 2016, then won again at 97kg in 2021.

Fujinami said she doesn't expect to make any major alterations to her wrestling style at the heavier weight.

"I have no intention of making any big changes in my wrestling style," she said. "I will still try to keep the opponent from getting at my legs, and take the initiative to score points. Still, I can feel the extra weight of four kilos, so how I increase my weight could affect how I perform."

At this year's East Japan league tournament, Fujinami's Nippon Sport Science University was relegated to second by Ikuei University, which won 2-1 in their duel meet. Ikuei got victories from Moe KIYOOKA (JPN) and Ami ISHII (JPN), who both won gold medals at last month's Non-Olympic Weight Category World Championships.
