Karsai Nei Tsang ＆ Jap Kasai

Feeling constantly tired, even after a good night’s sleep?

Feeling mentally and physically stuck?

Noticing a drop in your masculine energy?

If any of these sound familiar, we invite you to experience our specialized detox care for men:

Karsai Nei Tsang × Jap Kasai

At 2SmiLe, we combine these two traditional Thai therapies into a deeply rejuvenating treatment tailored specifically for men.

What is the treatment like?

Your session begins with a full-body oil treatment from the back side.

Using slow, rhythmic movements, we gently work through your neck, shoulders, back, hips, and legs—helping you release tension and reach a deeply relaxed state.

Next, we move to abdominal care through Karsai Nei Tsang.

This technique focuses on relieving tension in your internal organs—improving issues like bloating, constipation, fatigue, and emotional blockages.

We then continue with Jap Kasai, a therapy that targets the male intimate area to support hormonal balance, improve circulation, and restore sexual vitality.

For deeper tension, coldness, or poor blood flow, we may use high-concentration oxygen oil (O2 Kraft) to enhance the treatment’s effectiveness.

Recommended for those who…

• Feel a decrease in libido or erectile function

• Often have a bloated stomach or sluggish digestion

• Struggle with emotional stress or insomnia

• Are concerned about early signs of andropause

• Want to maintain masculine energy as they age

Men in their 20s to 60s have experienced this treatment and found real benefits.

Caring for your health now can make a noticeable difference in the years to come.

Final Thoughts

These therapies are still rare in Okinawa—but that’s exactly why we introduced them at 2SmiLe.

We want to provide a safe space where men can openly address concerns that are often hard to talk about.

Fatigue, sexual issues, chronic discomfort, emotional tension—

You deserve a space where you can release it all and reconnect with yourself.

This is a new choice for modern men.

We invite you to experience it for yourself.
