Why this leaning score
The language used is generally neutral, but the inclusion of Japanese Prime Minister Sanae Takaichi's statement about it being a 'race against time' to rescue those trapped suggests a slightly sympathetic tone towards the government's efforts.
Written under an earlier scoring contract, which gave a paragraph rather than checkable quotes. Re-analysing this article replaces it.
