Boulder problems

5D in the Japanese bouldering grading system.

Sweden

Mt. Kasagi, Gifu, Japan

There is some debate over this problem. Aidan Roberts first ascent used a brutal shoulder move and crimp in the roof. Will Bosi using a wobbly block in the roof, he also broke 3 feet in the lower section of the problem. Both gave the problem 8C.

In early 2025 Harry Constantine made a shock ascent, using different beta throughout and a wider foot for the first move. Aidan did use this foot in his ascent just for the second move, not the first move as Harry did, meaning a break is unlikely, although not implausible. Eli Cartwright then made the 4th ascent with a variation of Harry's beta, and proposed 8A+. Following Eli's ascent, Harry agreed a grade around 8B would be appropriate, however wasn't very firm on his suggestion.

It seems the date of specific foot breaks are unknown.

After this in mid 2025, a bloc in the roof which previous ascentsionists had noted was insecure broke, as well as the left hand starting hold breaking off, making the problem significantly easier again. Callum Amos then climbed the problem, estimating a grade of 8A/+.

'Classic' limestone eliminate bouldering.

A Jerry Moffatt project, featuring one of the hardest moves around at the time, it succumbed to the mighty strength of Paul Higginson. Less powerful sequences now exist.

Secret location due to sensitive access.

Originally climbed as a sport route at around 8b+, now typically climbed above pads.
