According to OECD data, Japanese adults average about 7 hours and 22 minutes of sleep per night \u2014 the least among major developed countries. For foreigners living in Japan, sleep problems are even more common, driven by work stress, culture shock, jet lag, and the anxiety of navigating daily life in a foreign language. If you are lying awake at night, staring at the ceiling, you are dealing with one of the most common health complaints in this country.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Sleep Problems<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Not all sleep problems are the same. Understanding your specific issue helps determine the right treatment:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sleep-onset insomnia:<\/strong> Difficulty falling asleep. You lie in bed for 30 minutes or more before sleep comes. This is often linked to anxiety or an overactive mind.<\/li>\n\n\n\n<li><strong>Sleep-maintenance insomnia:<\/strong> Waking up multiple times during the night and struggling to get back to sleep. This is often associated with stress or depression.<\/li>\n\n\n\n<li><strong>Early-morning awakening:<\/strong> Waking up at 3 or 4 AM and being unable to return to sleep. This is a classic symptom of depression.<\/li>\n\n\n\n<li><strong>Non-restorative sleep:<\/strong> Sleeping enough hours but waking up exhausted. Your sleep lacks quality even if the quantity seems adequate.<\/li>\n\n\n\n<li><strong>Circadian rhythm disruption:<\/strong> Your body clock is misaligned \u2014 you are wide awake at midnight and cannot wake up in the morning. Common after international travel or in people with irregular schedules.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Why Sleep Problems Are So Common Among Expats in Japan<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Work stress:<\/strong> Long hours, performance pressure, and the challenge of working in a cross-cultural environment keep your nervous system in &#8220;fight or flight&#8221; mode, making it hard to wind down at night.<\/li>\n\n\n\n<li><strong>Anxiety:<\/strong> Worrying about language mistakes, social interactions, visa renewals, finances, or your future in Japan activates your brain when it should be shutting down. See <a href=\"\/en\/column\/anxiety-types\/\">understanding anxiety<\/a>.<\/li>\n\n\n\n<li><strong>Screen time:<\/strong> Blue light from phones and computers suppresses melatonin production. Many expats spend evenings on screens \u2014 catching up with friends in different time zones, browsing social media, or watching content in their native language.<\/li>\n\n\n\n<li><strong>Alcohol:<\/strong> Japan has a strong drinking culture, and many expats use alcohol to unwind. While alcohol may help you fall asleep faster, it fragments sleep architecture and reduces sleep quality significantly.<\/li>\n\n\n\n<li><strong>Environmental factors:<\/strong> Japanese apartments can be noisy (thin walls), hot and humid in summer, and have different mattress styles (futons) that take time to adjust to.<\/li>\n\n\n\n<li><strong>Loneliness and depression:<\/strong> Both conditions disrupt sleep patterns. See <a href=\"\/en\/column\/loneliness\/\">loneliness as an expat<\/a> and <a href=\"\/en\/column\/expat-depression\/\">depression in expats<\/a>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">When Insomnia Becomes a Medical Problem<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Occasional poor sleep is normal. Insomnia becomes a medical concern when:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It occurs three or more nights per week<\/li>\n\n\n\n<li>It has lasted for more than three months<\/li>\n\n\n\n<li>It significantly affects your daytime functioning \u2014 concentration, mood, energy, work performance<\/li>\n\n\n\n<li>You have become anxious about sleep itself \u2014 dreading bedtime, worrying about not sleeping<\/li>\n\n\n\n<li>You are relying on alcohol, over-the-counter sleep aids, or other substances to sleep<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Chronic insomnia is not just annoying \u2014 it has real health consequences. It increases the risk of depression, anxiety, cardiovascular disease, obesity, and impaired immune function. It also significantly raises the risk of accidents.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sleep Hygiene: The Foundation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before considering medication, start with sleep hygiene \u2014 the set of habits and environmental factors that promote good sleep:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Consistent schedule:<\/strong> Go to bed and wake up at the same time every day, including weekends. Your body clock needs consistency.<\/li>\n\n\n\n<li><strong>Limit screen time before bed:<\/strong> Stop using phones, tablets, and computers at least 30 minutes before bed. Use night mode or blue light filters if you must use screens.<\/li>\n\n\n\n<li><strong>Create a cool, dark environment:<\/strong> Use blackout curtains, earplugs, and an air conditioner or fan. Keep the room temperature around 18\u201320\u00b0C.<\/li>\n\n\n\n<li><strong>Avoid caffeine after 2 PM:<\/strong> This includes green tea, which is ubiquitous in Japan and contains meaningful amounts of caffeine.<\/li>\n\n\n\n<li><strong>Limit alcohol:<\/strong> Avoid drinking within 3 hours of bedtime.<\/li>\n\n\n\n<li><strong>Exercise regularly:<\/strong> Physical activity improves sleep quality, but avoid intense exercise within 2 hours of bedtime.<\/li>\n\n\n\n<li><strong>Use the bed only for sleep:<\/strong> Do not work, eat, or scroll through your phone in bed. Your brain needs to associate the bed with sleep, not wakefulness.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Medical Treatment Options<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If sleep hygiene improvements are not enough, a doctor can help with several approaches:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Medication<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Japan has several types of sleep medications available by prescription:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Non-benzodiazepine hypnotics:<\/strong> Such as zolpidem (Myslee) and eszopiclone (Lunesta). These are effective for short-term use with fewer side effects than older sleep medications.<\/li>\n\n\n\n<li><strong>Orexin receptor antagonists:<\/strong> Suvorexant (Belsomra) and lemborexant (Dayvigo) are newer medications that work by blocking the brain&#8217;s wakefulness signals. They are effective and have a lower risk of dependency.<\/li>\n\n\n\n<li><strong>Melatonin receptor agonists:<\/strong> Ramelteon (Rozerem) helps regulate the circadian rhythm and is particularly useful for circadian disruption.<\/li>\n\n\n\n<li><strong>Low-dose antidepressants:<\/strong> For insomnia associated with anxiety or depression, certain antidepressants have sleep-promoting effects at low doses.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Treating the Underlying Cause<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Insomnia is often a symptom of another condition \u2014 depression, anxiety, burnout, or chronic stress. Treating the root cause often resolves the insomnia. This is where psychosomatic medicine excels: by looking at the full picture of your physical and mental health, the doctor can identify and address what is actually keeping you awake. See <a href=\"\/en\/column\/stress-physical-symptoms\/\">the connection between stress and physical symptoms<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Over-the-Counter Sleep Aids in Japan<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Japanese pharmacies sell OTC sleep aids (primarily diphenhydramine-based products like Drewell), but these are intended for occasional use only. They are less effective than prescription medications and can cause daytime drowsiness. If you are relying on OTC sleep aids regularly, it is time to see a doctor.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Get Help With Your Sleep<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">At Tokyo Hub Clinic, Dr. Ichiro Kamoshita, M.D., Ph.D., evaluates sleep problems in the context of your overall health \u2014 physical, mental, and lifestyle factors.
