South Korea Protests Japanese Warlord’s Appearance at Asian Games Ceremony: Why the 2026 Nagoya Games Face a Diplomatic Row 

The appearance of a historical Japanese warlord at a welcoming ceremony for the 2026 Asian Games has triggered a diplomatic and sporting controversy, with South Korea lodging a formal complaint over a figure associated with Japan’s invasions of Korea.

The dispute centres on Toyotomi Hideyoshi, a Japanese military leader whose campaigns against Korea in the late 16th century remain a sensitive chapter in the two countries’ shared history. South Korea’s protest has put the spotlight on the challenge of staging a major international sporting event amid unresolved historical sensitivities.

What happened at the Asian Games welcoming ceremony?

The controversy began on September 15, when a ceremony was held at Nagoya’s Kinjo Pier to welcome the Costa Serena cruise ship, which is being used to accommodate athletes and officials during the 2026 Aichi-Nagoya Asian Games.

The performance featured three historical Japanese warlords associated with the Nagoya region: Oda Nobunaga, Toyotomi Hideyoshi and Tokugawa Ieyasu. While the figures are part of the region’s historical and cultural identity, Hideyoshi’s inclusion prompted criticism in South Korea because of his military campaigns against the Korean peninsula.

Why is Toyotomi Hideyoshi a sensitive figure in South Korea?

Hideyoshi was the Japanese military leader behind the invasions of Korea between 1592 and 1598, known as the Imjin War. The campaigns caused widespread destruction and remain a significant episode in Korean historical memory.

The sensitivity also reflects the broader history of relations between the two countries, including Japan’s colonial rule over Korea from 1910 to 1945. Consequently, a figure celebrated in one country’s regional history can carry a very different meaning for people in another.

What did South Korea say about the incident?

The Korean Sport & Olympic Committee (KSOC) sent a formal complaint to the Aichi-Nagoya Asian Games organising committee and the Olympic Council of Asia on September 16, expressing regret and calling for measures to prevent a similar incident.

South Korea’s delegation chief, Lee Sang-hyun, said he respected local culture but regretted that greater consideration had not been shown towards the Korean delegation. He also emphasised that the team’s priority was to focus on the sporting competition.

How did Asian Games organisers respond?

The organising committee said the performance was intended to introduce the host region’s culture and tourism, rather than endorse a particular historical figure or communicate a historical message.

It acknowledged that ceremonies at an international sporting event can be interpreted differently by audiences from different countries and said it would ensure future programmes were appropriate for the Games.

As of September 17, the KSOC said it had not received a formal response to its complaint from either the organising committee or the Olympic Council of Asia.

Why has the 2021 Tokyo Olympics resurfaced in the debate?

The controversy has also revived memories of a dispute during the Tokyo Olympics in 2021, when South Korea displayed banners at the athletes’ village referencing Admiral Yi Sun-sin, a celebrated Korean naval commander who fought against Hideyoshi’s forces.

The banners drew objections in Japan, and the International Olympic Committee subsequently asked South Korea to remove them.

Some South Korean commentators have pointed to the earlier episode while questioning the apparent difference in how historical figures associated with the two countries have been treated at sporting events.

What does this mean for the 2026 Asian Games?

The dispute highlights the difficulties of organising an international sporting event in a region where historical memories remain politically and culturally sensitive.

For Nagoya, the warlords are part of its regional heritage. For South Korea, Hideyoshi is associated with a devastating invasion. The disagreement illustrates how a ceremony intended as a cultural welcome can be interpreted differently by participating nations.

With the Asian Games bringing together athletes from across Asia under the slogan “Imagine One Asia”, the episode has raised questions about how organisers can celebrate local history while remaining sensitive to the experiences of international delegations.
