Japan's Prime Minister Kōishi seems to have taken foreign diplomats aback with her unique approach to diplomatic manners. Detailed reporting about what exactly was surprising is not clear yet, but diplomats worldwide appear to be expressing both astonishment and intrigue. The incident took place during an unspecified, recent diplomatic engagement.

In Japan, diplomacy is deeply rooted in traditional etiquette and respect, where every action and spoken word can carry significant meaning. Prime Minister Kōishi's unconventional approach has sparked lively debates among the public, with some praising her refreshing style and others expressing concern over potential breaches of protocol.

In the US or EU, diplomatic standards are also upheld with great care, though there might be more tolerance towards individualistic styles of expression. Therefore, diplomats in these regions may perceive Prime Minister Kōishi's behavior with less surprise, viewing it more as a personality trait rather than a protocol breach.
