The line was subject of some controversy in Japan c.2020 after repeats were claimed that drifted onto slightly easier ground to the left. It was later clarified by first ascensionist Tokio Muroi that a sloper on Zutsu was out. [1]
It’s not known if all the repeats before the clarification followed the strict line.
