Kinbaku Roca / Mammal

Today was a non-BDSM photoshoot, but during a short break, we also did a little rope and took a few photos. 今日は、非SMジャンルの撮影の日でしたが、合間に少しだけ、縄をして写真も撮りました。

I did some rope today. It was fun. Rope is always so much fun. But I still don’t really understand why. I keep tying without fully understanding it. When the person being tied gets excited, that excites me too. And when I get excited, that in turn excites them. I think there is definitely a kind of

mammal Vol.2, my collection of kinbaku photography, has been selling extremely well, and I have just ordered another reprint. This is already the third printing. I’m truly grateful. Recently, alongside my work on the next issue of Roca, I have been immersing myself in writings and archival materials

These photographs were taken last August. I really love shooting outdoors in the rain. Until now, Roca has featured many photographs taken outdoors, while mammal has focused mainly on indoor studio shoots with fetish clothing. These photographs, however, do not seem to fit comfortably into either of

I am currently developing and editing photographs I took last summer for Roca Vol.6. I am a little surprised that nearly a year has already passed since the shoot. The pace at which I take photographs is far faster than the pace at which I publish the magazine, and as a result, more and more unpubli

Here are a few preview shots from a very recent shoot. I picked out several photos from roughly the first ten minutes of a nonstop two-and-a-half-hour session. It was such a good time. The next day, I was so exhausted that I could barely move.

In the end, this is the kind of work I love most. Whenever I stop overthinking, tie the way I want, and photograph the way I want, my work always seems to return to compositions like this.

I've come to feel that kinbaku photography works best when it balances both eroticism and emotion. The challenge is that emphasizing one often weakens the other, so finding that balance is never easy. On this particular day, I intentionally approached the shoot with a stronger focus on the emotional

These photos and videos were taken in February 2025. At the time, I was trying out a tie that my friends Yuki and Miya had taught me. What I find so beautiful about this tie is that no matter what position the model takes, there is no comfortable way to rest. It leaves them enduring continuous disco

This is a behind-the-scenes video from the December 2024 photo shoot featured in yesterday's post. It was originally available only on the members-only page, but I'm making it available for free for a limited time. If you're interested, I hope you'll check it out. Ren6-2 (Vimeo)

These photos were taken with Ren in December 2024. At that time, I was on leave from my day job, which meant I had much more time to focus on photography than I do now. Once a week, we would meet at the studio in the morning and continue shooting until around 8 p.m. Spending entire days working toge

I think I first met Ren about six years ago. At the time, we were simply people who happened to go to the same SM bar. I would see her there from time to time, but we had never really spoken. Then the pandemic began, I stopped going to the bar, and I stopped seeing her altogether. About five years p

I think it was about six years ago when I first tied Akane. Since then, we haven’t worked together very often, but a few times every year, without fail, we find ourselves making photographs together with rope. I’ve always felt that we created images I loved, but the photographs we’ve been making rec

Over the past year, Ren and I explored a wide variety of scenes, dynamics, and ideas together, creating an enormous number of photographs along the way. To be honest, I would have loved to include all of them in mammal Vol.2. But a photo book needs its own coherence, and many images—however much I l

The photo book mammal Vol.2, created together with Ren, is finally finished. Ren is both a collector of fetish fashion made from materials such as latex and PVC, and an enthusiast of BDSM culture. I’ve been photographing with her regularly for around two years, and this book is a collection of those

No rope this time.

2024 was probably around the time when content restrictions were not as strict as they are now, so I feel like I was shooting a lot more nude kinbaku photography back then. Recently, because of increasingly strict platform restrictions as well as changes in my own personal preferences, I’ve been sho

Today’s rope felt right somehow. The shape just came together naturally. But if I tried to do the exact same thing again, it probably wouldn’t work. That fleeting, one-time nature of kinbaku.

I used to have access to Hinako’s studio, and back then I could do kinbaku shoots endlessly in the best possible environment. That studio is gone now, and these days I often find myself struggling to find places to work. I really need to find a new studio soon. This photo was taken with Ren in Novem

（日本語版も後ろのほうに載せています） The other day, I attended a talk event by Norio Sugiura. The event traced the history of his career, from its beginnings to the present day, alongside many of his photographs. Listening to the stories behind the work and seeing those beautiful images from different periods of his

These photos were taken in May 2022 with Jun. At the time, I was still doing suspension quite often. I was completely absorbed in rope and photography, and I enjoyed experimenting with everything I had just learned. I also loved spending time with Jun, tying in the same place every week. Both my rop

In September 2024, I had my first shoot with the model Ren. Since then, we have been working together frequently for over a year and a half. She is also a collector of fetish outfits, and being able to incorporate a wide variety of her wardrobe into our shoots has been a great pleasure.

These photos were taken in June 2023. Recently, I’ve been going through my older work and discovering many images with a very different atmosphere from what I create now—it’s been really interesting to revisit them.

Recently, it has become harder to share nude kinbaku photography on social media. In Japan, many people in the SM community have had their accounts suspended on X (Twitter). I also appreciate kinbaku with clothing, but I still deeply love nude kinbaku photography. I hope that one day, we can create

I uploaded a video to Patreon the other day, but it was quickly removed due to a Vimeo policy violation. I’ve now tried using a different video streaming service—are you able to watch it without any issues? For the time being, I’m planning to continue posting updates using this service. If anyone ha

I have several favorite forms of SM play besides kinbaku, but among them, one that ranks near the top for me is play involving a septum piercing.

These photos were taken with Ren on February 6.

The studio I had been using until now has finally closed and is no longer available. At the moment, I’m trying out various rental studios while searching for a good new space. I really liked this studio. It had a beautiful clothing rack, so I decided to use it for this play.

I’ve added a new piece of stage equipment to the studio. It’s a rectangular steel frame custom-made for me by Tetsuzo, a well-known SM gear maker in Japan. When shooting kinbaku in the studio, I’m often struggling to find solid places to anchor the rope—but this solves everything. It feels versatile

Recently, I’ve been visiting the Abnormal Museum in Iidabashi and reading SM magazines from the Showa era. This photo was inspired by a cover image from a very famous magazine — do you know which magazine and which issue it is? Normally, I tend to start shooting almost without thinking, beginning wi

Happy New Year. I think I’ll be taking lots of gote-shibari photographs again this year.

I’ve done so many shoots with Ren, and we’ve taken countless photos of her. Among them are many favorites, even some I’d consider true masterpieces. But the images we created this time are easily among the very best. When I tie and shoot day after day, almost like a daily ritual, there are those rar
