MOS Burger Near Tokyo Station: How to Find It, Order & What to Try

Tokyo Station seriesPart of my Tokyo Station Yaesu Guide — choose the right exit, check whether a place is inside or outside the JR gates, and plan time before trains or buses.

MOS Burger Yaechika is a practical Japanese-born burger stop just outside Tokyo Station’s JR ticket gates. I visited the branch to photograph the underground route, English self-order screens, cashless payment notice, table-number system, seating, and the meal I actually ordered. The shop opened on August 19, 2026 in the North 1 area of Yaesu Underground Shopping Mall.

1. Quick answer: MOS Burger Yaechika at a glance

2. Where is MOS Burger near Tokyo Station?

MOS Burger Yaechika is in Yaesu Underground Shopping Mall (Yaechika), in the North 1 area on basement level B1. It is outside the paid JR area, so travelers arriving by train must pass through a Yaesu ticket gate before visiting. You can also enter Yaechika directly from the street without holding a JR ticket.

The branch’s interior is intentionally different from a typical fast-food shop. Yaechika describes a calmer design using natural textures and subtle shadows. The large table and wall finish incorporate soil from Narimasu, the Tokyo neighborhood where MOS Burger began.

3. How to get to MOS Burger from Tokyo Station

I photographed this route starting at JR Tokyo Station’s Yaesu Central Exit. I stayed underground after the ticket gate, so you do not need to go outside.

1. 1
   Leave through Yaesu Central Exit

   Follow the yellow station signs and pass through the JR ticket gates. MOS Burger is outside the paid train area.

2. 2
   Continue straight toward the underground shopping area

   After the gate, walk into the Yaesu-side concourse and continue toward Gransta Yaesu and Yaechika.

3. 3
   Keep walking through Gransta Yaesu

   Use the blue arrows I added to my photo and stay underground. At the junction near L’Occitane, turn left toward Yaechika North.

4. 4
   Use Donki as your landmark

   After turning left, the compact Okashi Donki and Osake Donki shop comes into view. Continue along the same passage toward MOS Burger.

5. 5
   Look for the large green MOS sign

   The open storefront and self-order kiosks are easy to see from the passage.

Continue straight past Donki, and you will find MOS Burger ahead. Look for the large green MOS BURGER sign and the self-order kiosks at the open storefront.

4. What makes MOS Burger different?

MOS Burger is not available only in Japan. It began in Narimasu, Tokyo in 1972 and now operates in Japan and several overseas markets in Asia. The useful reason to try it here is not exclusivity: it is a Japanese-born chain that adapts the hamburger to Japanese tastes.

• MOS Burger: the signature burger combines a patty, tomato, onion, and a generous original meat sauce.
• Teriyaki Burger: MOS introduced its Japanese-style sweet-and-savory teriyaki burger in 1973.
• MOS Rice Burger: grilled rice patties replace the bread bun; the chain introduced its first version in 1987.
• Made to order: MOS says its food is prepared after the order is received, so allow more time than for a burger already waiting under a heat lamp.

5. How to order at MOS Burger Yaechika

The ordering system below is the exact flow I photographed and used. The kiosk has an English-language option. Its large sign says cash is not accepted at the self-order machine; customers using cash, gift certificates, or coupons should use the staffed register.

Step 1: Start the kiosk and choose dine-in or takeaway

Step 2: Choose the burger, customizations, and set

Select a menu category, then tap the item photo. The English screen lets you order the burger alone or choose a set and adjust available ingredients. Read every selection before continuing; options and prices change.

Step 3: Choose a number tag and enter it at the kiosk

This is the branch-specific step that is easiest to miss. For dine-in, take any available number tag from the holder beside the kiosk. Scan its barcode when prompted, or type the printed number and select Confirm. Do not leave the tag behind.

Step 4: Pay, choose an open seat, and display the tag

Complete payment using one of the cashless methods shown on the kiosk. If you need to pay cash, stop and use the staffed register instead. Carry the numbered tag to any open seat and place it upright where staff can see it. You do not need to stand at the counter waiting for the food; a staff member brings the order to the matching number.

Step 5: Return the tray after eating

Take the tray, cup, and wrappers to the designated return area when you finish. If you cannot find it or are unsure how to separate anything, hand the tray to a staff member and say “Sumimasen.” Do not leave large rubbish on the table unless staff specifically asks you to.

6. What should you try at MOS Burger in Japan?

My order: Double Tobikiri Cheese with Hokkaido Cheese

I ordered the Tobikiri Cheese Burger Double Patty ~Hokkaido Cheese~ (ダブルとびきりチーズ ～北海道チーズ～), made with two 100% domestic-beef patties. The burger itself was listed at ¥1,020 on the kiosk I photographed, and the regular fries-and-drink set added ¥450.

7. How to eat a MOS Burger without making a mess

The signature MOS Burger and other saucy items are easier to eat when they stay inside the wrapper. MOS itself recommends using the wrapper to catch the sauce.

1. 1
   Do not remove the burger completely

   Hold the wrapper around the lower half so tomato, sauce, and fillings stay contained.

2. 2
   Rotate it as you eat

   Turning the burger helps the wrapper collect sauce rather than letting it run onto your clothes or the table.

3. 3
   Use the remaining sauce

   Dip a fry into the sauce left at the bottom of the wrapper, or ask staff for a spoon if needed.

4. 4
   Return the tray

   Gather the wrapper and cup neatly, then take the tray to the return area.

8. Can you get breakfast at MOS Burger?

Yes. MOS Burger Yaechika opens at 7:30 a.m., and MOS officially lists its breakfast menu, Asa MOS, until 10:30 a.m.. It can be convenient before a Shinkansen or highway bus because the branch is connected to Tokyo Station’s underground Yaesu network.

• Good for: travelers who want a seat and a freshly prepared breakfast rather than a convenience-store meal.
• Allow time: food is made after ordering, so do not arrive immediately before a train or bus departure.
• Check the live menu: breakfast items can sell out and some items may not be handled at every branch.
• Plan your route afterward: allow extra time to return through the correct JR or Shinkansen gate, or reach the appropriate highway-bus terminal.

9. Seating, takeaway, and useful tips for travelers

• Choose an open seat after ordering. During my visit, the number tag—not a fixed table assignment—connected my kiosk order to the table.
• Power is available at selected seats. The photographed counter position has an outlet, but do not assume every table does.
• Keep luggage out of the aisle. The branch is beside a busy underground passage. Ask staff where to place a large suitcase rather than blocking seats or an exit.
• Takeaway is available. Select Take Out on the first kiosk screen and follow the pickup instructions shown for that order.
• Families can use the shop. A table is easier than a counter when available, but one adult should keep the order tag visible and supervise children around the busy entrance.
• Check allergens before paying. The kiosk has allergen and nutrition buttons, and MOS publishes an English allergen list. Shared preparation means the information is not a zero-contact guarantee.

10. My first-time visitor tips

• Use the staffed register when paying cash. The kiosk’s large notice explicitly says cash is not accepted there.
• Review dine-in versus takeaway first. Correcting it later can require staff assistance.
• Read the set details. A burger, side, and drink are separate choices, and customizations appear on later screens.
• Budget more than 10 minutes. My food arrived about 10 minutes after I paid, but ordering, eating, clearing the tray, queues, and made-to-order preparation require a wider planning window.
• Use current signs as your final guide. Underground tenants and detours can change, and the linked multilingual PDF was issued before this MOS Burger branch opened.
