The 19-year-old World Championship silver medallist was born in the host city and tops the season's best list this term with 319.84 points, achieved at the Lombardia Trophy challenger event in Italy. 

Uno also clinched victory at Skate Canada in Regina in October, one of six events on the Grand Prix circuit which served as qualifiers for the flagship finale in Nagoya.

Only the top six in the men's, women's, pairs and ice dance rankings have earned a spot for the competition at the Nippon Gaishi Hall to guarantee a world class line-up.

American Nathan Chen, the top ranked qualifier who won the Rostelecom Cup in Moscow and Skate America in Lake Placid on the Grand Prix circuit, is sure to provide Uno with fierce competition.

Two Russian Grand Prix winners - Cup of China champion Mikhail Kolyada and NHK Trophy winner Sergei Voronov - are also in the field, while Americans Adam Rippon and Jason Brown complete the competitors. 

Brown replaces Boyang Jin as first reserve after the Chinese skater withdrew through injury.

There is no place for Spain's double world champion Javier Fernández, despite his win at the Internationaux de France, while Japan's Olympic gold medallist and defending Grand Prix Final winner Yuzuru Hanyu will also not be involved after a season hit by injury.

In the women's event, Russia's defending champion Evgenia Medvedeva has withdrawn through injury.

The 18-year-old won the Rostelecom Cup and NHK Trophy and topped the overall rankings but broke her foot last month.

It means that Russian colleague Alina Zagitova could be the favourite after two golds at the Cup of China and Internationaux de France.

The 15-year-old won the Junior Grand Prix Final on her international circuit debut last year and could now add the senior crown, already boasting the season's best of 218.46 points.

Canada's Kaetlyn Osmond, the Skate Canada champion, 2012 world champion Carolina Kostnet of Italy and Russia's Maria Sotskova are also in the field, while hosts Japan will be represented by two skaters.

Wakaba Higuchi will debut in the Grand Prix Final and Satoko Miyahara, the Skate America gold medallist, has been called in to replace Medvedeva.

In pairs, China's reigning world champions Wenjing Sui and Cong Han won the Cup of China and NHK Trophy to top the rankings.

Grand Prix Final holders and European champions Evgenia Tarasova and Vladimir Morozov of Russia will provide competition after they also won twice at the Rostelecom Cup and Internationaux de France.

Skate America winners Aljona Savchenko and Bruno Massot of Germany and Canadians Meagan Duhamel and Eric Radford, the Skate Canada winners, will also compete in a strong field alongside China's Xiaoyu Yu and Hao Zhang and Russia's Ksenia Stolbova and Fedor Klimov.

Ice dance will likely see a battle between France's ranking leaders Gabriella Papadakis and Guillaume Cizeron, Canada's world champions and Grand Prix holders Tessa Virtue and Scott Moir and Americans Maia and Alex Shibutani.

All three couples won two events each with the Canadians winning their home event and then adding the NHK Trophy.

Papadakis and Cizeron won the Internationaux de France after an earlier success at the Cup of China, with the Shibutani sibilings triumphing at Skate America and the Rostelecom Cup.

United States teams Madison Chock and Evan Bates and Madison Hubbell and Zachary Donohue are also in the field, alongside Italy's 2014 world champions Anna Cappellini and Luca Lanotte.

The men's, pairs and ice dance competitions will start tomorrow, alongside the beginning of the junior events.

Senior winners in Nagoya will win a prize of $25,000 (£19,000/€21,000).
