The first POPUP of August is a scorching hot collaboration!!
We’ve invited two brands with serious character to shake up the vibe in Toranomon.
Returning to Circles Tokyo for the first time in a while is RAWLOW MOUNTAIN WORKS, and making their debut here is HIKER TRASH!
We are hosting both brands for a simultaneous POPUP event!!
【RAWLOW MOUNTAIN WORKS】
RAWLOW MOUNTAIN WORKS is a Japanese mountain gear brand established in 2015. Founded by two designers with over 20 years of experience in bag making, the brand focuses on backpacks and proposes tools that move fluidly between the mountains, travel, and everyday life.
【HIKER TRASH】
There is a peculiar breed of people in this world who embark on journeys known as "long-distance hiking."
Because these nomads are often trail-worn and disheveled, they are affectionately called "Hiker Trash."
Hiker Trash spend so much of their lives on the trail that they don't distinguish between the mountain and city life.
In other words, it means wandering freely and being true to yourself anywhere you go.
That spirit of HIKER TRASH invites you on that kind of exhilarating journey.
Both RAWLOW MOUNTAIN WORKS and HIKER TRASH are brands with deep, long-standing ties to Circles, and they are also our friends who have connected with us through cycling.
And for this event, both Ryotaro from RAWLOW MOUNTAIN WORKS and Iwashi from HIKER TRASH will be at the shop for both days.
Just thinking about these two being together in Toranomon makes me feel like something exciting is bound to happen. (Haha)
Furthermore, a Morning Ride will be held on Sunday, August 2nd!
Both of them will be joining, so it’s a perfect opportunity to listen to stories about travel and adventure while chatting in the saddle. Plus, there will be a special bike, too…!! I’ll share the details in the second half.
But first, let me introduce the many special items we’ve prepared for this POP UP.
RAWLOW MOUNTAIN WORKS
Two classic & new models! Plus exclusives!!
RAWLOW MOUNTAIN WORKS just held a POPUP in Nagoya, and for this Tokyo-Nagoya tour, we’ve prepared plenty of items for Tokyo too!
The must-have item, which was a huge hit in Nagoya, is the Bike’n Hike Saddle Bag.
This signature "wearable saddle bag" from RAWLOW MOUNTAIN WORKS, which has been crafted since the brand's inception, has finally been updated.
The materials and design follow the new Colorado Pack, making it even more heavy-duty. By refining the inner core material and the side gussets, the stability when mounted to the saddle has been significantly improved.
The capacity is 8–10L. It’s a great size for day rides as well as 1-night, 2-day touring trips.
Additionally, a "Circles original color 'Blue'" will also be available.
When using your bike for travel, it's always a pain to figure out what to do with your bags when you take them off, right? This Bike’n Hike Bag lets you detach it from the bike and wear it as a backpack.
It's perfect for when you want to go for a quick hike during a tour, or just hop off your bike to wander around town.
Next up.
The newly released Colorado Pack will also be available!
The colorways, which feel like a nod to 80s and 90s American products, are really great.
This model has been resized as a lumbar pack that works for a wide range of activities, including low-mountain hiking, mountain biking, and fishing.
Along with the new Medium size, we’ve prepared a Small size, which is close to the traditional Nuts Pack.
Featuring adjustable belts on both sides, it fits securely even during intense rides like MTB or when carrying heavier loads.
And we’ve also brought the apparel line that started last year!
You rarely get the chance to see these in person, so please don't miss out.
Ryotaro-san of RAWLOW MOUNTAIN WORKS is a true "pro of play" who spends every season exploring different fields.
Since it's rare to have the chance to meet Ryotaro-san, please be sure to talk to him directly—he can share personal stories and insights into gear selection that only someone who has truly put their products through the wringer can offer.
HIKER TRASH
This is the first time HIKER TRASH has been hosted at Circles Tokyo.
First, let me introduce the director of HIKER TRASH, Iwashi-san.
Ryosuke "Iwashi" Kawato (Sketch)
Beyond his work as an illustrator, he directs the apparel brand "HIKER TRASH."
At Circles, nobody calls him "Kawato-san." Everyone calls him "Iwashi-san" with affection.
Iwashi-san is a Triple Crown hiker who has completed the three major American long-distance trails.
Confronting the harshness of nature requires tough physical strength, but the gear you wear is just as crucial. He produces hiking socks that he truly feels are necessary to survive those grueling, long-distance journeys.
They’ve become a staple item among the Circles staff.
Whether you’re already a fan or just learning about the brand, please come pick up the products and hear the stories behind their creation and the long-hike episodes directly from Iwashi-san himself.
You’ll surely find that the value of those socks feels multiplied.
Besides socks, we’ll have a wide lineup including bags, bandanas, and T-shirts.
Personally, I’ve been getting into hiking lately, so I’m really looking forward to hearing what they have to say.

A rare two-day opportunity where both Ryotaro-san and Iwashi-san will be at the shop together.
Just looking at the gear is fun, but the greatest charm of this POP UP is the ability to talk directly with these two. About mountains, bikes, travel, and play—let's spend some quality time together at the shop.
And as I mentioned at the start, we're holding a Morning Ride!

It’s a valuable opportunity for some leisurely saddle talk while riding with Ryotaro-san and Iwashi-san.
