Product Story

New Buddy for Hiking

Akira Natsume (Yamatomichi Founder)

To test Yamatomichi’s THREE pack in 2014, I hiked from the Oyashirazu coast of the Japan Sea to Hirayu, passing through the Northern Japanese Alps. I extended my hike further into the very deep alpine area of the Southern Alps from Jizo-ridge, and ultimately reached Tohyamago area, the southern part of Nagano Prefecture. After this trip, I realized that on my next long hike I wanted to travel much lighter so that I could almost just jump from one mountain to the other.

I tried to visualize the ideal backpack for this kind of hiking and came up with an image of a small, simple, and obviously lightweight backpack that I thought would be “just the right thing.” It didn’t have to be either eccentric-looking or technically advanced, but a pack I would just grab without any hesitation—just like the classic silnylon backpack I yearned for in the early days of ultralight hiking.

In those days, technically advanced materials such as X-Pac that we use in the THREE backpack, and Cuben hybrid composite were all the talk, while rip-stop nylon material like silnylon was considered a little outdated. But I was determined to create a new backpack with Skylite that has a similar texture to silnylon, in a kind of homage to the simple backpack that brought about ultralight hiking back in the day.

I also decided that the front pocket should be in a mesh.

Before I made THREE with its mesh pocket similar to the one we use on MINI2, I had been skeptical about adopting mesh for the rainy climate of the Japanese mountains. I initially felt mesh pockets were impractical since the rain could easily soak the contents. Even during my hiking test of the mesh-pocketed THREE, I didn’t like how everything seemed to be getting wet in the beginning, but after several days of hiking, I gradually came to like the function of the mesh pocket. I could stow my still moist tent in the morning without much thought, and the mesh material allowed me to easily see what was inside the pocket.

Sure, things could get wet easily in a mesh pocket, but they would dry quickly too. Hiking became more carefree and natural for me than ever before, and the mesh pocket perfectly synced with my feelings at that time.

With all this in mind, I decided to base the new design on our MINI, but in different material and with mesh pockets. The original MINI fits your body when you carry it on the upper part of your back, and it is so comfortable that you feel as though you can go on walking forever. The new pack was going to be an updated version of the MINI so I simply called it MINI2.

In 2015, I traveled from the Japan Sea through the Pacific Ocean, traversing through the mountains in a fastpacking style with a prototype of the MINI2.

It was autumn, and the first snow of the season gently covered the mountains. I carried only the bare essentials to minimize the base weight down to 2.2kg, limiting the total weight, including food and water, to under 5kg.

I was in complete harmony with my surroundings. The journey seemed to open up a whole new world. The MINI2 became like a part of me throughout the journey, allowing me to run parts of the trail and jump from one mountain to the other as I had initially dreamed of doing.

I use MINI2 daily now, and I just use waterproof Ziplocs when I stow items in the mesh pocket on a rainy day.
Without a doubt, MINI2 is more of a mountain-oriented backpack than a town-use daypack. And I can’t wait to take it on another long trail soon again.


Form and Function

High Capacity Mesh Pocket

On designing the MINI2, we decided to modify the original MINI’s front pocket to mesh. The front pocket is very important since the MINI2 is lidless, as is the case with most ultralight packs. The front pocket is used for storing small items, rainwear, and snacks. At times, even your tent, tarp, or groundsheet may end up here.

Suppose you wake up in the morning to find it raining, pack up all your gear inside the tent, or under the tarp. You are almost ready to leave, but what do you do with the tent you are in? With our MINI2, you just tuck the tent in the front pocket after packing up everything else inside and are ready to go. Backpacks with the capacity of 25-35 liters rarely have such a large front pocket that can store items as big as a tent, but the MINI2 is equipped with a high capacity front pocket similar to that of our THREE backpack that allows for just this. Normal mesh fabric tends to tear easily and are difficult to repair if torn, so we used a stronger and slightly heavier hard mesh on MINI2’s pockets to keep you from worrying out on the trail.

Designed for Comfortable Hiking

The MINI2 is designed to carry up to around eight kilograms of total weight and comfortably distribute the load in the upper back part of your torso, as well as around your chest without relying on your waist to support the weight. This frees your waist from the load and makes it easy for you to comfortably walk around the often steep mountain trails in Japan.

Highly Versatile

The MINI2 has a long tubular roll-top and large-volume front and side pockets with a capacity total of over 30 liters. You can be creative and use the top strap, bungee cords and bottom attachment loops to carry even more.


Minimalist Pad

The Yamatomichi Minimalist Pad (45 x 90 x 0.5cm / 43g) is folded in four and inserted as the back panel instead of an internal frame. Although a harder pad is better for a heavier load, the Minimalist Pad is designed to properly work when the pack weight is 8 kg or less. The Minimalist Pad is removable and can be used as a sleeping pad or a supplementary pad.

Optional Parts and Items (sold separately)

We have a full line-up of optional parts and items that enhance MINI2’s function and capacity.
Choose and use them to maximize the MINI2’s capability according to your needs.

Overnight Hiking with the MINI2

Several years ago, the standard volume of backpacks for ultralight hiking was around 35-45 liters. However, gear is increasingly getting lighter and more compact, allowing for overnight hikes with much smaller packs. Many traditional hikers might still be skeptical about overnight hiking with a small 25-35 liters backpack like the MINI2, we wanted to share a couple of gear list examples for overnight stays with the MINI2.

Akira Natsume’s (Yamatomichi Founder) gear list for fastpacking from the Sea of Japan coast to the Pacific Ocean coast

For this fastpacking trip, Akira traversed from the Oyashirazu coast of the Sea of Japan to Hirayu, passing through the Northern Alps. He traveled extremely lightly this time, carrying only the bare essentials with a base weight of only 2.2 kg and just under 5 kg in total pack weight. With the MINI2, he was able to keep going for six days without any problems.

Yusuke Kurosawa’s (Previous Yamatomichi Staff) gear list

The below is what ultralight hiker Yusuke Kurosawa brings when he is hiking the Japanese Alps in the summer or lower-lying mountains in the spring or autumn. By eliminating items you really don’t need, you will find the MINI2 more than large enough for overnight hiking.


Skylite Fabric

The standard fabrics used for ultralight backpacks tend to be lightweight, water-resistant, and durable with a certain thickness such as Cuben fiber (dyneema composite fabric) and X-Pac that we also use.

Though all of these are excellent materials, we imagined something else when we thought of creating a genuinely ultralight Yamatomich backpack. We wanted to go back to basics to the first homemade silnylon packs sewed in someone’s garage back in the mid-90s when ultralight hiking was just taking off.

Back then, my first impression on seeing the ultralight backpacks made of ridiculously thin fabric from the US was “Can I really go hiking with this? It looks almost like a garbage bag!” But these innovative packs were also at the core of the appeal of ultralight hiking for me.

In terms of overall functionality, Skylite is inferior to X-Pac or Cuben hybrid, though having a wonderfully shiny and silky texture that reminds one of silnylon. That being said, I choose this paper-thin fabric to express the nostalgia of the 1990s, wanting to share the excitement I felt at that time with a new generation of young hikers who might think “Can I go hiking with this?”. My answer is clear, “Yes, this is just right!”


Size M L
42~69 67~85
78~95 92~110
150~175 170~190
背面長/Back Length
45~54 54~57

As a rough guide, we recommend the L size for people over 175cm, but there are people 170cm tall and the L is perfect for them. We recommend trying before buying.

Please Note

  • Q.

    Will it fit a petite woman?


    The shoulder straps are designed slightly shorter than those of American or European backpacks. One of our customers, a 153cm tall woman, uses the MINI with no problem. If you are concerned about the fitting, we recommend you to test it at one of our stores.

  • Q.

    Do you repair it?


    We repair it for a fee depending on the extent of the damage. If you wish to repair a small hole or rip by yourself, we recommend you use the silicone seam sealer “SilNet” for a quick fix. Please note that the main fabric, Skylite repels normal adhesive used on most repair tape.
