Can Do Near Tokyo Station: Marunouchi Oazo 100-Yen Shop Guide

Tokyo Station seriesPart of my Tokyo Station Guide — use the correct side of the station, leave the JR ticket gates, and make a quick practical stop before your next train or hotel check-in.

I visited Can★Do Marunouchi Oazo on October 24, 2026 and bought bath bombs and small vehicle toys for family travel. This 100-yen shop is on B1 of Marunouchi Oazo, directly across from the Marunouchi North Exit side of Tokyo Station. It is a useful stop when you need an inexpensive activity for a hotel evening, a simple travel item, stationery, snacks, or one more small distraction for a child—but not every product costs ¥100, and you should always check the age guidance for toys with small parts.

1. The quick answer

Worth a stop?

Yes—especially when Tokyo Station is already part of your day

Can★Do Marunouchi Oazo is close enough to the Marunouchi North Exit for a focused shopping stop. The branch is outside the JR paid area, so you must leave the ticket gates. Go with a short list, check the price printed on each shelf label, and allow extra time if you are unfamiliar with Tokyo Station.

For parents, the best value is not a huge souvenir haul. It is finding one compact item that solves the next part of the trip: a bath bomb for a permitted hotel bathtub, an age-appropriate quiet toy, stickers, a pouch, or another small activity that can help a tired child reset.

3. How to walk from Tokyo Station

This photo route begins at the JR ticket gates for Marunouchi North Exit. Can★Do is outside the paid area, on B1 of Marunouchi Oazo.

Start: Find the Marunouchi North Exit ticket gates

Inside Tokyo Station, follow the yellow signs marked Marunouchi North Exit (丸の内北口), then leave through these JR ticket gates.

Step 2: Go underground, then turn right by the coin lockers

Take the stairs down into the underground passage. At the bottom, continue to the coin lockers and turn right as shown in the second photo.

The red star and CanDo logo make the store easy to confirm on the directory.

◎ With a stroller or large luggage

The photographed route uses stairs. Use the signed elevators instead of carrying a stroller or suitcase, and allow extra time to rejoin the B1 passage. Tokyo Station’s Marunouchi North Exit and Marunouchi Underground North Exit are different gates, so check the exact wording on each sign.

4. What I actually bought

I focused on two types of low-cost family items: vehicle toys for simple pretend play and bath bombs containing surprise animal mascots. The store had a large bath-bomb display with many themes and characters, although designs, prices, and stock can change. These items are compact, easy to pack, and can turn a quiet hotel evening into an activity rather than more screen time.

Why the bath bombs worked well at the hotel

A bath bomb gives the child something to anticipate at the end of a long sightseeing day, while the parent still controls when and where it is opened. The surprise mascot can also become a memory of the trip. The selection photographed here included dinosaur and creature themes, but the available series may be completely different when you visit.

The surprise mascots are small parts—not toys for unsupervised young children.

Japan’s Consumer Affairs Agency advises adults to follow the stated age range and keep small parts away from young children. If the mascot is outside your child’s age range, an adult should remove and store it immediately. The same check applies to wheels, ladders, and any detachable parts on a vehicle toy.

5. Why this stop can help families with young children

I found this kind of small purchase genuinely useful while traveling with a young child. Travel days ask children to wait in unfamiliar places: on trains, in hotel rooms, at restaurants, and while adults repack. A small, inexpensive activity can redirect attention before everyone becomes tired. The key is to choose for the child’s actual age—not simply buy the smallest or cutest item.

Situation	Useful choice	Parent check
Hotel bath	A sealed bath bomb used by an adult	Ask whether the hotel permits bath additives; check ingredients and age guidance; rinse the tub afterward.
Hotel-room play	A larger age-appropriate vehicle or simple activity	Inspect for detachable pieces and keep the toy away from the child during sleep.
Train ride	Stickers, drawing supplies, or another quiet item suited to the child	Avoid loose miniature pieces that can roll away, be swallowed, or disturb other passengers.
End-of-day reset	One new activity, not a full bag of toys	Introduce it before the child is overtired and keep the routine simple.

Do not use bath additives in a public bath, shared hotel bath, or any bathtub whose rules prohibit them. If a child has sensitive skin, check the package and use your normal pediatric or medical guidance rather than assuming a low price means a gentle formula.

6. Prices and checkout

A “100-yen shop” is a store category, not a guarantee that every item costs ¥100. Many standard non-food products marked ¥100 before tax cost ¥110 at checkout, while this branch also carries products at ¥200 or more before tax. Read the shelf label and the price printed on the package before deciding.

Keep each item with its shelf label in mind. Similar-looking toys or bath products may have different prices.
Check the tax-included total at the register. The large “100” associated with the store category may not be the final amount.
Use the payment logos at the checkout. The official listing says the branch accepts cash, credit cards, electronic money, and code payments, but individual brands can change.
Do not rely on telephone stock checks. Can★Do asks customers not to call this branch for product availability, orders, or holds.

7. Before you go

1
Write a three-item list
For example: one hotel activity, one practical travel item, and one small souvenir. A short list keeps a quick stop from becoming a luggage problem.
2
Check your departure time
Tokyo Station takes longer to navigate than the short walk between the North Exit and Oazo. Return to the correct platform with a generous buffer.
3
Read the package before giving an item to a child
Check the age range, warnings, ingredients, number of pieces, and whether any part could detach.
4
Ask the hotel before using a bath bomb
Some bathtubs or properties restrict colored, fragranced, oily, or foaming additives. Never assume permission.
5
Photograph the package before discarding it
This preserves the product name, ingredients, warnings, and manufacturer details while keeping your luggage light.

8. Frequently asked questions

Is Can★Do Marunouchi Oazo inside Tokyo Station?

No. It is on B1 of Marunouchi Oazo, outside the JR ticket gates. Leave through the Marunouchi North Exit, go down to the underground passage, and follow the Oazo signs shown in this guide.

How long does the walk take?

Marunouchi Oazo is close to the Marunouchi North Exit, but your total time depends on your arrival platform, crowds, luggage, and familiarity with Tokyo Station. The photo route uses stairs, so allow extra time if you need an elevator.

What time does the shop open?

When I checked the official listing on October 24, 2026, it showed 8:00–22:00 Monday through Friday and 9:00–21:00 on Saturdays, Sundays, and holidays. Special closures and building inspections can change access, so recheck before a special trip.

Does everything cost ¥110 including tax?

No. Many basic non-food products do, but the branch also carries items priced above ¥100 before tax. Always check the current shelf label.

Are the bath-bomb mascots suitable for young children?

Do not assume so. The photographed mascots are small enough to create a swallowing or choking risk. Follow the package’s age label and keep small parts out of reach; an adult should remove and store the mascot when it is not age-appropriate.

Can I use a bath bomb in my hotel bathtub?

Only if the property allows bath additives and the product is appropriate for the user. Ask the hotel first, follow the package directions, and rinse the tub. Do not use one in a shared or public bath.

Can the store reserve an item for me?

The official store page asks customers not to request product availability information, orders, or holds by phone. Visit with flexible expectations because designs and stock change.

On-site visit, official information, and child-safety note

I visited and photographed Can★Do Marunouchi Oazo on October 24, 2026. I checked the address, floor, hours, payment categories, product categories, and stock-inquiry policy against the official Can★Do store page.

Hours, payment brands, prices, products, and stock can change; confirm the current signs and package.
