Controversy has once again cast a shadow over Japan's preparations for the 2020 Games after French prosecutors launched an investigation into $2 million in payments allegedly paid to help Tokyo secure the Olympics.
John Coates, chairman of the IOC's Tokyo 2020 coordination commission, attempted to deflect attention away from potentially sticky issues on previous visits, such as last year's row over the cost of the main stadium.
As scandal-hit Tokyo organisers sweat over the French probe into cash funnelled into a Singapore bank account, said to have been paid to the son of disgraced former athletics chief Lamine Diack, Japanese officials will be more grateful than ever for the usual IOC platitudes.
Allegations the payments were improper, first reported by Britain's Guardian newspaper two weeks ago, sent shockwaves through Japan.

Prime Minister Shinzo Abe ordered full cooperation with French authorities after being grilled by opposition leaders in Japan's parliament.
"For Japan, as a democratic country, the use of bribes and dirty money brings dishonour to the country," said Katsuya Okada, president of Japan's Democratic Party. "We need to clarify all the facts."

Takeda has refused to disclose details of the consultancy contract to lawmakers, citing a "confidentiality obligation".
He told lawmakers on Tuesday that the payments "were compensations for a consultancy contract, and we'd never thought that the money would be sent to Mr. Diack".
With the Rio Olympics less than three months away, regular coordination activities have been postponed to later in the year and replaced by an executive meeting, although Coates is expected to inspect the Tokyo 2020 sailing venue.
Tokyo has been hit by a series of controversies since beating Istanbul and Madrid in September 2013 in the race to host the coveted Summer Games.
Further embarrassment followed when Tokyo organisers ditched their 2020 Games logo after allegations of plagiarism and the threat of legal action from a Belgian designer who claimed it too closely resembled the emblem of a theatre in Liege, Belgium.
However, those fiascos pale in comparison to accusations of murky payments made to a consultant called Ian Tan Tong Han of Singapore-based Black Tidings, said to be an associate of Diack's son Papa Massata Diack.
