Yakushima (Pt.5) – Mocchomudake; The Yonic Mountain That Crushed Us

Map of Mocchomudake’s hiking course

Our mission today was to climb Mocchomudake. Known as one of Yakushima’s most challenging hikes. Kei couldn’t stop sniggering at the name of this mountain. Mocchomu apparently refers to the yonic shape of the rock formation at the top…

We were climbing the vagina mountain.


Mocchomudake’s Trailhead

Starting at 270m, the beginning of the hike leads you through lush green forest and is a steep climb at an average of 25-30°. We found ourselves building up a sweat quite quickly here.

Follow the pink ribbons!

This trail is not maintained like Jomon Sugi, and you have to look out for the little pink ribbons otherwise you will get lost quite quickly. They lead you over little root-ledges and across mossy rocks and silver streams. 

We kept our eyes peeled. Furthermore, after saying for days that every tree root looked like a snake, and worried that we would come into contact with one of the most poisonous snakes in Japan… we found a snake. Run!

Concentration-face is back

The summit sits at 994m high, and not one part of the climb gives you a rest-break. You are climbing steps, rocks, roots and ropes the entire way up. Again, I would recommend strong footwear (unlike mine!).

We reached 800m and our hopes started to peak.

Then we asked a passing hiker if we were nearing the top, he replied with “Ha! Not yet! You have lots of ups and downs to go before reaching the top!”


Bandai Sugi – 3000 years old

At this point we stopped for a break to see the two ancient Jōmon Sugi on this trail; Mocchomutaro Sugi, and Bandai Sugi. They were incredibly tall, and hollow inside as they had rotten from the thousands of years of growth in this wet climate. 

Collecting Yaku-water from the stream

The water that flows through the forest is also particularly tasty, with a mossy green taste. Make sure to collect it from running water and check upstream for dead animals first 👍🏼

Mocchomudake’s Peak

The last part of the climb was a killer, as the exhausted hiker had said, it ascends and descends 3 times before you reach the top. We could already see hikers at the peak.

Climbing up, abseiling down

Despite not being a maintained route, there were helpful ropes for pulling yourself up the sheer granite rock faces. Slippy when wet, I wouldn’t dream of attempting this climbing in the rain. We were lucky.

Climbing the peak’s rock face

The last hurdle was a huge rock perched on the summit. You have to put all of your trust into a single knotted rope to finish this hike.

The view was Saikou!!!

The view of south Yakushima’s coastline was stunning. Mocchomudake is usually shrouded with clouds so having this view on a clear day was something special.

Unfortunately we couldn’t get a photograph of the rock formation that Mocchomudake was named for… so you’ll just have to use your imagination…or not.

Legendary 70 year old ladies abseiling down the peak’s rock face

We also met a young guide with 3 very special ladies. They had started at 5:30am that morning, and they had just summited after a 7 hour hike (it was 12:30). 

Did I mention that they were 70 years old? 


View from the summit

If I am still climbing when I’m 70 years old, I will be extremely happy. 

Happy to have conquered this peak!

After having sweet Yakushima oranges on the summit, and getting lost in the view of the blurred sea horizon and patchwork fields along the chalked outline of the coastline, we decided to make our descent.

The descent was much harder…

For us, in total it was a 6hr full-body climbing experience. Pretty fast.

Eventually, we overtook the ladies on the way down, even though my knees felt like a 70 year old’s at this point. I learned that you really have to know your own fitness limits to attempt hikes like this, and I believe that I had reached mine. 

We waited for the ladies at Senpiro Waterfall at the bottom, and they arrived at 5:30pm.  They had taken a full 12 hours to achieve what was a highly challenging hike!

Good on them!


Traveller’s Tips:
Rating on YES! Yakushima:
Level 4/5  |  Distance: 6km | Time 7-8 hours | Altitude 270m ~994m
Bring lunch with you, you will need the energy! There is a little space on the summit to have lunch if the weather is fine. There is also a tiny shrine at the start and at the base.
Mocchomudake’s summit tends to be shrouded in cloud quite often, and to be honest if you can see cloud I would not attempt this hike. It is a challenging course for the reward of an amazing view at the top. 
If you have strong ankles, a good fitness level and a strong mind to tackle some vertical roped sections (you can’t give up halfway on this hike!) then I recommend it for you.
Free parking at the base of the walk to Senpiro Waterfall, where the trailhead starts. Has toilets and a small shop at the base also.
