Client Experiences

I did two 4-hour sessions with Yuki during my vacation in Japan. Her approach to Jab Kasai is deceptively intense despite the surprisingly light pressure she applies, and the first session genuinely felt like my testicles were being crushed. Beyond the muscle release from the full-body work and a few days of tenderness afterward, I was hit with an unexpected wave of emotion that I can only describe in one word: longing. It caught me completely off guard, even though her website does mention this can happen.

I was compelled to book a second appointment toward the end of my trip. The discomfort was noticeably more bearable this time, and I leaned fully into meditation throughout the treatment, which guided me into a depth of relaxation I’ve never reached during a standard massage. The aftereffects were also more pronounced. My body felt wonderfully light in the way it does following a great deep tissue session, but Jab Kasai seemed to amplify those benefits and make them linger far longer. I walked away feeling rejuvenated, with noticeably less tension throughout my body and pelvic floor. Cannot recommend it enough, provided you’re brave enough to handle the pain.

Thank you for your hard work.
It has been a relaxing session!

The best massage I’ve ever had. Thank you so much Yuki. You are a sweetheart! 

This was my first time receiving this kind of massage, so at the beginning I felt unsure and a bit suspicious. But compared to a normal massage, the energy increases afterwards, and I realized she is actually a very safe and trustworthy therapist.

I think the testicles might be the most neglected part of my body, so it was definitely a surprise to feel them moved in ways they’ve never been moved. Sometimes painful, yeah, but the overall effect felt liberating.
I feel more open now, like expressing myself more honestly. Is that normal? Either way, it feels good. Big respect to you for traveling so far to learn this technique.

I would like to thank Yuki for the delightful treatment and for the professionalism. For me it was the first Jab Kasai treatment ever. She went above and beyond my expectations, dedicating the necessary time and attention to ensure a thorough, enjoyable and effective Jab Kasai treatment process. Their willingness to listen and address my concerns with compassion and understanding was remarkable. I felt youthful and revived like a teenager. I strongly recommend to have this experience.

After just one session, I noticed a clear change in my body. My urination felt stronger than before, which genuinely surprised me, as I had felt my flow was becoming weaker. It gave me a renewed sense of vitality.

At first, I felt slightly self-conscious about exposing my body, but your professionalism and steady presence quickly put me at ease. By the time I stepped into the shower after the session, I felt completely refreshed, as if my whole system had been reset.

The Jab Kasai work had a powerful impact. I felt a surge of energy building in my abdomen, intense yet invigorating. At moments, the sensation was so strong that I almost wanted to vocalize my reaction, but afterward I felt deeply revitalized.

The prostate-focused treatment brought an unexpected sense of release, almost like a reset within my body. It felt both surprising and cleansing, leaving me with a new sense of ease and balance in that area. I also noticed improvements in my erections and overall physical condition.

You created an environment where I felt completely comfortable, free from awkwardness or hesitation. That sense of ease allowed me to fully receive the benefits of the session, leaving me feeling more energized, balanced, and in better overall health.

Thank you so much, Yuki!! It meant a lot to me. You’re the best.

During the Jabkasai treatment, I noticed a particular area around my navel that felt unusually firm. When pressure was applied, the sensation of pain seemed to linger in that spot.
Compared to before the session, I could clearly feel an improvement in the firmness and fullness of my erections, as well as better blood circulation. The prostate healing brought a gradual warmth that spread throughout, accompanied by a deep, almost elusive sensation that slowly filled my body—a unique and deeply relaxing experience.
The head massage at the end was incredibly soothing. Before I knew it, I had drifted off into sleep in an instant. By the time the session was over, both my body and mind felt refreshed, leaving me with a profound sense of relaxation and contentment.

Getting bit older I decided it is time to take more care of my body and my own wellbeing so I wanted to try Jabkasai for the first time in my life.I selected Yuki because of the vast training background explained on her website. I was simply thrilled by this new experience , guided by the gentle touch of Yuki’s warm hands. The 2 hours passed by very quickly for me( too quickly actually),Yuki has a very good flow in her massage , I could relax very well and my thoughts drifted far away. A moment of peace and bliss.For me it felt like Yuki knows me very well (although we met first time that day).Reading about Jabkasai I was somehow warned that the massage is partly painful (but that is part of it)but also here Yuki knows exactly the right spots and how strong to touch with her own technic.I expected to be drained and exhausted after the massage, but the opposite was the case,I felt balanced and energized next day.I am already thinking to plan my next session and look forward to that.

The massage is purely professional and very therapeutic and focuses on all areas where blood flow is essential to the overall performance. The balance between adequate pressure and soft iterations creates a strong sensation that leaves one feeling absolutely rejuvenated!

Hey Yuki san, thank you so much. It was a pleasure talking with you, and I had a wonderful “Yuki Kasai” session.

Thank you so much ! It was an amazing experience! I felt completely relaxed, cared for, and energized afterwards. It’s clear that this work is truly special. I left with a renewed sense of ease and lightness in my body.
