Prince Harry arrives at Tokyo Airport on a visit to Japan

Prince Harry smiled as he arrived in Tokyo today, telling reporters it was “good to see you again” ahead of a summit on sports, community and philanthropy.

The Duke of Sussex was radiantly filmed walking through the city’s Haneda Airport among the crowd of passengers, wearing a black shirt and a dark cap bearing the logo of the Archewell Foundation which he runs with his wife Meghan Markle.

A reporter could be heard off camera asking Harry, “How do you feel about being in Japan for the first time in four years?” And he replied, “Good to see you again.”

A video broadcast on the Japanese TV network ANN News showed Harry arriving at the terminal along with his old friend, Argentine polo player Nacho Figueras.

The duo will attend Harry’s annual fundraising polo match in Singapore this Saturday, which he has said will help underprivileged youth affected by HIV/AIDS.

Omid Scobie, co-author of the controversial Harry and Meghan biography Finding Freedom, tweeted a video of the Duke’s arrival in Japan just after noon UK time.

He added: “Many fans are waiting for Harry to arrive. The royal family has always had a large following in Japan (especially Princess Diana) and interest in the Sussexes remains high. Fun fact: Finding Freedom is one of the few royal books to get a full Japanese release!’

The Duke arrived in Japan today ahead of his attendance at the ISPS (International Sports Promotion Society) Sports Values ​​Summit ‘Special Edition’ tomorrow.

Harry will participate in a panel discussion with former New Zealand rugby player Dan Carter, an ambassador for ISPS Handa who sponsors the polo cup,

Sentebale chairwoman Sophie Chandauka and Royal Australian Navy Veteran and Invictus Games gold medalist Steve James are also expected to attend.

In addition, the event in Tokyo will be attended by Professor Wim de Villiers, the Rector and Rector Magnificus of Stellenbosch University in South Africa.

Harry will then host the Sentebale Polo Cup in Singapore on Saturday, with the money raised going towards supporting the organization’s clubs and camps program, which provides psychosocial support to young people living with HIV.

Last month, Harry said: ‘The annual Polo Cup is essential to Sentebale’s vital work to ensure that children and young people are healthy, resilient and able to thrive.

‘The money raised this year will benefit our clubs and camps program, which provides intensive psychosocial support to young people living with HIV.

“At a time when being HIV positive is no longer a death sentence, we are empowering young people to know their status, stay healthy and eliminate stigma so they can break the cycle.”

Since 2010, the annual Polo Cup has raised over £11 million to support Sentebale’s work with children and young people affected by poverty, inequality and HIV/AIDS in Southern Africa.

The Duke will play in the Royal Salute Sentebale team, against the Singapore Polo Club team captained by the charity ambassador, Mr Figueras.

Sentebale was founded in 2006 by Harry and Prince Seeiso of Lesotho to help the most vulnerable children and young people in Southern Africa receive support to lead healthy and productive lives.

It first started working in Leosotho before expanding its efforts to Botswana and is active in four key areas: strengthening the social and emotional well-being of people living with or affected by HIV; help provide access to health and social services; encouraging youth advocacy and building the skills and livelihoods of individuals.
