Located in Sakae-machi, Takikawa City, Hokkaido, Nikaido Mental Clinic is a clinic specializing in psychiatry, psychosomatic medicine, and child psychiatry. The clinic director, Dr. Masashige Nikaido, is a designated mental health physician and holds multiple specialist qualifications, including specialist and instructor credentials from the Japanese Society of Psychiatry and Neurology, certification from the Japanese Society of Child and Adolescent Psychiatry, and certification as a child mental health specialist. With this professional background, the clinic has established a system capable of addressing a wide range of age groups, from children to adults and elderly individuals. The clinic treats a diverse range of symptoms, including insomnia, adjustment disorder, depression, menopausal disorders, neurosis, manic-depressive illness, schizophrenia, and panic disorder, as well as developmental disorders and ADHD. The clinic's approach to school refusal is one of its distinctive features; when the patient has difficulty visiting, consultations are available with parents alone, and for treatment-resistant cases, the clinic provides personalized support that incorporates their unique mathematics learning instruction. Appointments are required, with consultations available Wednesday through Saturday until 7:00 PM. Saturday appointments make it easy for patients with work or school commitments to attend. The clinic also offers English-language services and is equipped with parking and barrier-free facilities.
