The Organising Committee have corrected a map on the "dream programme" section of their official website which did not include Japan. 

A correction was demanded by the Japan Sports Agency, via the South Korean Embassy, after they received complaints from members of the public. 

The omission was reportedly blamed on a "simple mistake", according to Associated Press.

It comes at a time of continuing territorial and historical tensions between the two countries. 

The map still uses the name "East Sea" for waters between the two countries, although Tokyo would prefer "Japan Sea".

In this context, a message of support from the Japanese Olympic Committee (JOC) comes as a boost for organisers desperate to improve ticket sales and show that the Games will be safe despite security concerns on the Korean peninsula. 

"The JOC is looking forward to participate in the Olympic Winter Games Pyeongchang 2018 and will be in Pyeongchang together with the athletes and the Japanese delegation whom have been training and preparing for the past four years," said the body's President Tsunekazu Takeda, a member of the International Olympic Committee (IOC) Coordination Commission for the South Korean Games.

"I know that Pyeongchang 2018 will ensure to provide a safe Games for the entire Olympic family."

Tensions have continued to rise in the region, following a series of missile tests by North Korea in recent months.

Two missiles have been fired over Japanese territory. 

Matters have been escalated further by the increasing rhetoric between United States President Donald Trump and North Korean leader Kim Jong Un.

Kim has warned that North Korea would consider the "highest level of hard-line countermeasures in history" against America in response to Trump’s repeated threats to destroy them.

French fencer turned Sports Minister Laura Flessel warned last week that her country could miss next year's Games if "our security cannot be assured".

National Olympic Committees, including in France as well as the United States, have since answered an apparent call to arms from the IOC to publicly declare their support.

The IOC have contacted all 205 National Olympic Committees asking them to "coordinate any media enquiries and responses" about the situation in North Korea with them.

It comes as they seek to avoid the largely unfounded fears over the danger of Zika virus before last year's Summer Olympics in Rio de Janeiro.

The JOC message is a particular boost because of the Organising Committee's hopes that large number of Japanese spectators will attend the Games.

Pyeongchang 2018 President Lee Hee-beom told insidethegames earlier this month that he was hoping to meet with the JOC and the Chinese Olympic Committee (COC) to help boost ticket sales and support in those countries.

No similar public message has yet been given by the COC.

The German Olympic Sports Confederation (DOSB) is among others to have delivered a message of support today.

DOSB President Alfons Hörmann said that "security for the entire team of Germany is at the top" of their priorities before saying that it is "currently considered too early" for "discussions on possible concrete measures".

"In the coming months, we will keep a close eye on the situation and the development and will continue to exchange information with both the IOC and the Federal Foreign Office," he added.

South Korea's Culture and Sports Minister Do Jong-whan has, meanwhile, said today that the country hope to use next year's event to promote peace through sport.

"Pyeongchang Winter Olympics is a good opportunity to send a message of peace and reconciliation to the world," the official was reported as saying by Xinhua following a meeting with foreign correspondents in Seoul.

A "truce resolution" was submitted to the United Nations General Assembly last week in an attempt to force a suspension of any conflict in the world during Pyeongchang 2018.
