Retail price: 1,980 yen Reasons to loosen the area around the sacrum: This area is where thick blood vessels gather and where many nerves pass through, including those connected to the pelvic organs, as well as the nerves of the parasympathetic nervous system. Stimulating this area can improve blood flow throughout the body. Also, there are acupressure points that enhance the function of the uterus, making it beneficial for gynecological issues! Introducing "Koshiretch mini," a cute, palm-sized sacrum-rocking item. Koshiretch, a popular compact acupressure device that you simply place on your sacrum (senkotsu) and gently rock while lying down, is now even smaller and palm-sized. It fits perfectly on the sacrum and allows for pinpointed treatment. If you want to stretch your lower back, Koshiretch mini is a great help. When you're concerned about your lower back, rock and stimulate it with Koshiretch! The sacrum is located in the center of the pelvis, which is the foundation of the body, and is a heart-shaped bone at the base of the spine. The sacrum is connected to the large gluteus maximus muscle, the piriformis muscle (an inner muscle of the buttocks), the long and large erector spinae muscles of the back, and the multifidus muscle (an inner muscle of the back). "Koshiretch mini" was developed with a focus on the perfect size, angle, and softness of the material to effectively target the sacrum. It stretches and strengthens the area around the sacrum, which is difficult to reach on your own. For concerns about your lower back and body discomfort, rock and stimulate with Koshiretch!
