Compassionate Care Rooted in Clinical Experience
Shizue Hayashi Ito, L.Ac. is a California-licensed acupuncturist with more than 25 years of clinical experience in Japan and the United States.
Throughout her career, Shizue has sought diverse clinical experiences, believing that each stage of her professional journey would strengthen her ability to provide comprehensive, individualized, and compassionate care.
She completed clinical training in Beijing, China, where she expanded her knowledge of Traditional Chinese Medicine and acupuncture. While practicing in California, she further developed her expertise through auricular therapy workshops led by Dr. Li, an internationally respected authority in the field.
After earning her National Board Certification in Acupuncture and Herbal Medicine (NCBAHM™, formerly NCCAOM®) and her California Acupuncture License, Shizue returned to Japan to work as a hospital-based shiatsu therapist at Josai General Hospital. Collaborating with physicians in a comprehensive health screening center broadened her understanding of preventive medicine, laboratory interpretation, brain health, and the importance of caring for the whole person—not just the symptoms.
She later joined Seishindo Kampo Pharmacy, where she provided individualized Kampo consultations while continuing her professional education in fertility, women’s health, allergies, dermatology, and integrative skincare. Working alongside experienced physicians and practitioners further strengthened her clinical expertise and holistic approach to patient care.
Her clinical experience further expanded through home healthcare, where she cared for patients recovering from stroke, living with neurological disorders, and receiving palliative and end-of-life care. These experiences deepened her commitment to compassionate, patient-centered medicine.
Today, Shizue integrates Japanese acupuncture, Traditional Chinese Medicine, Kampo medicine, auricular therapy, and evidence-informed modern techniques to provide personalized care that supports healing from the inside out. Her background in Kampo medicine, skin physiology, and integrative dermatologic care also provides a strong foundation for her cosmetic microneedling practice, supporting not only skin rejuvenation, but also long-term skin health from within and on the surface of the skin.

Philosophy
My goal is not only to relieve today’s symptoms, but to support lasting health through personalized care, patient education, and prevention.
Our Services
We carefully consider your current symptoms, health history, constitution, lifestyle, and personal goals to provide treatment that is thoughtfully tailored to your needs at every visit.
Your first visit is more than an acupuncture treatment—it’s an opportunity for me to understand you as a whole person, not just your symptoms.
Using the principles of Traditional East Asian Medicine, I carefully evaluate your current concerns, health history, lifestyle, sleep, digestion, stress levels, and overall constitution to better understand the underlying cause of your condition.
Based on this comprehensive assessment, I create a personalized treatment plan tailored to your individual needs. Depending on your condition, your treatment may also include auricular therapy, cupping, Japanese shiatsu, stretching, therapeutic bodywork, or ear seeds to help achieve the best possible results.
Follow-up treatments build upon your initial evaluation and are adjusted according to your progress, current symptoms, and response to previous care.

The ear is much more than a hearing organ. It contains hundreds of reflex points that correspond to different areas of the body and is one of the few places where the auricular branch of the vagus nerve reaches the skin. This unique anatomy allows gentle stimulation of the ear to influence the autonomic nervous system and support the body’s natural regulatory processes.
By carefully evaluating the ear and stimulating specific points, auricular therapy may help reduce stress, improve sleep quality, relieve pain, and support the body’s natural healing response.
When appropriate, ear seeds are applied to provide gentle, continuous stimulation between treatments.

With years of clinical experience working in a traditional Japanese herbal pharmacy, I learned that the same diagnosis does not always require the same herbal formula. Each prescription should be selected according to the individual’s constitution, symptoms, lifestyle, and the underlying pattern of imbalance.
Using the principles of Traditional East Asian Medicine, I carefully evaluate the whole person—not just the symptoms—to recommend herbal formulas that complement acupuncture and support long-term health.
Herbal consultations are available as a standalone service or as part of your personalized treatment plan.
Personalized cosmetic treatments use precise microneedling or gentler nanoneedling techniques to support smoother-looking texture, brighter tone, hydration, and overall skin vitality. The approach is selected according to your skin condition, sensitivity, goals, and preferred downtime.
