OTC Medicines at Japanese Pharmacies
Travelmin (トラベルミン) — Japan's leading OTC motion sickness medication. Contains diphenhydramine and scopolamine. Very effective. Available at pharmacies and major convenience stores. Take 30 minutes before travel.
Travelmin Junior — child-formulation of the same product, available for children from age 6.
Seabandブレスレット (Seaband) — acupressure wristbands that apply pressure to the P6 (Nei Kuan) acupressure point on the inner wrist. Available at larger pharmacies. Some travelers find them helpful as a supplement to medication.
Ginger products — ginger capsules, ginger tea, and concentrated ginger ale (Wilkinson, Schweppes). Ginger has the best evidence among natural remedies for motion sickness. It is particularly helpful for the nausea component.
Antihistamines — dimenhydrinate (contained in Travelmin) and similar antihistamines available in combination cold medicines also reduce motion sickness.
Important note: Most motion sickness medications cause drowsiness. Do not drive after taking them. Plan rest time after long bus or boat journeys if you have taken medication.
Prevention Strategies for Japan Specifically
On mountain buses: Choose a window seat near the front of the bus. Looking forward at the road rather than sideways significantly reduces symptoms. Avoid reading or looking at your phone.
On the Shinkansen: Request a forward-facing seat (進行方向の席, *shinkō hōkō no seki*) when booking. This aligns your body's motion sensing with the direction of travel. Book through your Japan Rail Pass reservation or at the JR ticket window.
On ferries: Stay on deck in fresh air if sea conditions allow. Fix your gaze on the horizon — this is the most effective non-pharmacological intervention for sea sickness. Avoid below-deck enclosed cabins if symptomatic.
On mountain roads: Sit in the front passenger seat or front rows of a bus. Do not eat a large meal within 2 hours of departure. Light snacks (crackers, ginger biscuits) are better than an empty stomach.
General tips: Avoid alcohol the night before; get enough sleep; stay well hydrated; avoid strong food smells before travel.
Finding a Doctor in Japan
If motion sickness is severe enough to significantly impair your travel and OTC options are insufficient, visit an internal medicine clinic (内科, *naika*) or a neurologist (神経内科) to discuss prescription options like scopolamine patches (Scopoderm, available on prescription in Japan) or stronger antiemetics.

FAQ
Q: Does the Shinkansen cause motion sickness?
A: For most people, no. The Shinkansen ride is extremely smooth compared to other forms of transport. However, sensitive individuals may experience discomfort during acceleration, deceleration, or on curves. Sitting in a forward-facing window seat and avoiding screen use minimizes risk.
Q: What is the best seat on a Japanese mountain bus for motion sickness?
A: The front seats behind the driver offer the most stable ride and best forward view. Avoid the back rows, which experience the most motion. If possible, book designated front seats when purchasing your bus ticket.
Q: How early should I take Travelmin before a journey?
A: Take Travelmin at least 30 minutes before you board. If you are taking a morning bus, take it with breakfast. Do not wait until symptoms start — motion sickness medication is far more effective as prevention than as treatment once symptoms have begun.
Q: Are there prescription motion sickness patches available in Japan?
A: Scopolamine transdermal patches (スコポラミンパッチ) are available in Japan on prescription. They are applied behind the ear 6–12 hours before travel and provide up to 72 hours of protection. They are the gold standard for severe motion sickness including sea sickness.
Q: Can children take Travelmin in Japan?
A: Travelmin Junior is formulated for children aged 6 and above. For children younger than 6, consult a pediatrician before giving any motion sickness medication.
Q: Is motion sickness the same as vertigo?
A: No. Motion sickness occurs only during movement and resolves quickly when movement stops. True vertigo (内耳性めまい, inner ear vertigo) causes a spinning sensation even at rest and may indicate inner ear conditions like BPPV, Ménière's disease, or labyrinthitis. If you have dizziness or spinning sensations when not moving, see an ENT or neurologist.
