What it is
Cosmos Pharmaceutical operates a nationwide drugstore network that began in Miyazaki Prefecture and later expanded across Kyushu, western Japan and parts of eastern Japan. Its official locator reported 1,735 stores in 38 prefectures. The chain emphasizes low everyday prices and a simple shopping model, which can appeal to travelers buying snacks, drinks, cosmetics and other daily necessities.
Cosmos uses an everyday-low-price model and generally emphasizes cash payments. Its official inbound shop list, however, advertises Alipay and WeChat Pay at named branches including Kabukicho 1-chome and Hiroo Station in Tokyo, Dotonbori and Shinsaibashi Minami in Osaka, and Tenjin Daimaru-mae in Fukuoka. These are specific supported examples, not a universal payment promise. Some stores, such as the Tenjin Daimaru-mae branch, are also listed as tax-free; compare shelf labels and branch services before shopping.
How to order
Step 1: Locating Suburban & Urban Mega Stores
Cosmos operates 1,735 stores across 38 prefectures:
- Look for the distinctive bright pink-and-green roadside signs featuring ディスカウントドラッグ コスモス or COSMOS.
- Cosmos has many suburban branches and some urban sites. For example, its Tenjin Daimaru-mae branch in central Fukuoka is listed on the official website and opens from 10:00 AM to 11:00 PM.
- Company FAQ says the standard schedule is 10:00 AM–9:00 PM, with exceptions. Stores generally close on January 1 and may close for renovations or inventory; check your location.
Step 2: Preparing Physical Japanese Yen Cash
- Payment Preparation: Have enough Japanese yen cash before shopping. Check the selected store for any accepted cashless methods rather than expecting them.
- Do not count on Visa, Mastercard, Suica, ICOCA, PayPay or Alipay at a Cosmos checkout unless you have confirmed that the specific store accepts the method.
- Do not count on an ATM at the shop. Use a bank, convenience-store ATM or another confirmed cash withdrawal point before visiting.
Step 3: Navigating the Giant Food & Pharmacy Aisles
- Grab an extra-wide shopping cart at the entrance.
- Frozen Foods and Groceries: Check the available freezers and shelves for packaged snacks, bread, bottled drinks, chilled or frozen foods; the range varies by branch.
- Private Brand "ON365": The company has an ON365 product range; look for its label on eligible products and compare unit prices.
- The Over-the-Counter Medicine Department: Find relief remedies for headaches, motion sickness, digestive upset, eye strain, and muscle fatigue.
- Consulting On-Site Staff: Ask a pharmacist or registered salesperson when one is on duty. Some medicines cannot be sold without the appropriate qualified professional; follow the label and staff instructions.
Step 4: Checkout & Cash Payment
- Bring your items to the register and follow the cashier's directions.
- The cashier scans your items and states your total.
- Pay as directed at that register; payment hardware is not identical at every shop. Pack purchases yourself at the available bagging area, as the company FAQ advises.
Step 5: Tax-Free Exemption Clarification
- The official branch page for Tenjin Daimaru-mae (Fukuoka) explicitly marks the store as tax-free. This is a branch-specific service; do not infer the status of other locations without checking their official listings.
- Under the November 1, 2026 refund regime, eligible customers pay tax-inclusive prices at an authorized tax-free shop and receive the tax refund only after customs confirm export on departure. At ordinary shops, standard consumption tax remains included.
What to order first
These are suggested product categories, not a guarantee of inventory. Check the actual shelf price and product label at your branch.
1. Cosmos Private-Brand "ON365" Snacks & Groceries
- What it is: Proprietary private-brand confectionery, roasted nuts, dried fruits, green teas, and pantry staples.
- Why buy it: House-brand packaged goods are worth checking against other options by product size, ingredients and shelf price.
2. Over-the-Counter Eye Drops & Cooling Sheet Packs
- What it is: High-efficacy Japanese eye drops (vitamin-enriched, cooling menthol) and thermal forehead gel sheets (Hiepita).
- Why buy it: Small eye-care and cooling products are convenient to pack; read medicine labels for indications and precautions.
3. Bottled Teas and Other Drinks
- What it is: 500ml and 2-liter bottled Japanese green teas (Ito En, Ayataka), sports electrolyte drinks (Pocari Sweat), and energy tonics.
- Why buy it: A shop stop is a convenient time to buy drinks for a longer journey; compare current shelf prices.

- What it is: Flexible pain-relief medicated patches containing felbinac or salonpas-style formulations for aching feet, shoulders, and lower back.
- Why buy it: Essential relief after days of intensive walking and sightseeing across Japan.
5. Japanese Sunscreens & Skincare Cleansers

Payment & practical info
Prices and details checked: October 2026.
- Accepted Payment Modes: Yen cash is the safe default. The official inbound pages list Alipay and WeChat Pay at named urban branches (Kabukicho, Hiroo, Dotonbori, Shinsaibashi Minami and Tenjin Daimaru-mae); confirm the selected store and service before paying.
- Tax-Free Exemption: Tenjin Daimaru-mae (Fukuoka) is explicitly marked tax-free in the chain’s official branch listing; do not assume all Cosmos outlets offer this service. At a participating, authorized tourist tax-free shop, purchases from November 1, 2026 are paid tax-inclusive. Eligible purchases generally total at least ¥5,000 before tax at the same store on the same day. The traveler completes customs export confirmation within 90 days, before checking baggage, and must take all goods in the purchase record out of Japan; food or cosmetics consumed in Japan cannot be refunded. The retailer or its refund provider returns the tax equivalent after customs confirmation, not the customs officer.
- Operating Hours: Hours vary by branch, and dispensing-pharmacy hours may differ from retail hours. Check the official store locator before visiting.
Good to know / Common mistakes
1. Plan to Pay with Yen Cash
The safest approach is to carry yen cash before you shop. Payment services differ by location, so check with the store before relying on a card or smartphone app.
2. Pharmaceutical Consultation Guidelines
Over-the-counter medicines have different sales requirements. A pharmacist is needed for certain categories; a registered salesperson can advise on some others. Staff cannot provide a medical diagnosis. Check the label, age restrictions, and instructions before purchasing.
3. Bring a Reusable Bag
Bring your own bag; check the branch for current prices on disposable carrier bags. The official FAQ confirms that customers generally bag their purchases themselves after checkout.
FAQ
Q1: Why should travelers bring cash to Cosmos?
Bring yen cash to avoid checkout problems where cashless payments are unavailable. Cosmos emphasizes everyday value, but actual prices should be compared using current shelf labels.
Q2: Is there an ATM inside Cosmos?
Do not assume there is an ATM at the store or that a foreign-issued card will work there. Withdraw cash at a confirmed ATM before you shop.
Q3: Does Cosmos have stores in Tokyo?
Yes. The chain's official store directory listed 11 shops in Tokyo and stores in Saitama, Chiba and Kanagawa. Use the store locator for addresses and services.
