Can you tell us more about the trip to Japan?
I’ve been wanting to come check out the climbing in Japan for a long time and decided this year would be a good one to come. My original plan was to see a few different areas and get a real feel for all the climbing. However once I arrived at Mt Mizugaki and saw how good it was and how much rock there was, I quickly realised I wanted to stay there for the whole trip.

There are hundreds of boulders and thousands of lines! I had a few boulders in mind I really wanted to do and managed to tick through all but one, Floatin! I think Floatin was at the top of the list and I got really close but my skin just fell apart and never really healed enough to make it work unfortunately. I will have to return for it.

Asaigmadara was by far the best boulder I sent and one of the best lines I’ve ever done. The line is around 15-20 metres high in total and the hard climbing only stops almost half way up the boulder, so it’s a real mental challenge as well as physical. The hard climbing revolves around one cool heel hook, a bad pinch and lots of two finger pockets.

Two 8B+/V14 lines I managed Decided and Hoto are also amazing and I really enjoyed climbing. Both using cool right heel hooks as well. I would definitely recommend them. My three weeks trip to Mt Mizugaki was incredible and I really enjoyed my time here in Japan. Main take aways are the rock is crazy sharp!!! The grades are a bit all over the place and the thought of bear attack is scary.
