Muji Japan Shopping Guide 2026: Must-Have Items

Muji Japan Shopping Guide 2026: Must-Have Items | TRVLOGUE

Ever wonder what to grab from Muji in Japan?

Whenever I travel to Japan, Muji is always a must-visit for me,

and the items I've personally bought and loved always find their way into my basket again on subsequent trips.

In this post, I'll be sharing my top Muji Japan recommendations, covering everything from daily essentials and stationery to delicious snacks.

Small Item Cases SS / M

SS size ¥120 / M size ¥150

While they come in various sizes,

I personally use the SS and M sizes.

I primarily use them for storing my accessories,

when I'm traveling, I used to frequently leave my rings or necklaces

next to the sink while getting ready.

But ever since I started using these cases, I haven't forgotten a single piece!

At home, they're perfect for holding small accessories like earrings, rings, and necklaces,

and even great for tidying up little bits and bobs like hair ties or clips.

Polishing Sheets for Precious Metals

3 sheets ¥199

These are polishing cloths used for maintaining silver accessories.

Since silver tarnishes when exposed to air,

it needs regular cleaning. These look just like glasses cleaning cloths,

and are perfect for cleaning tarnished rings or earrings.

At ¥199 for three sheets, the price is incredibly reasonable,

and if you're someone who wears a lot of silver jewelry like I do,

it's definitely a worthwhile purchase.

I don't recall seeing these in Korea,

I've only ever spotted them at Muji in Japan.

Compact Pen 0.5mm

These compact pens come in a beautiful array of colors.

Refills are sold separately, so once you run out, you just swap the refill – super convenient!

I find myself buying them frequently.

I mainly use them when I'm studying Japanese,

to color-code my notes,

They don't bleed or stand out too much like highlighters, and they make organizing notes by color a breeze, which is why I consistently repurchase them.

Cable Storage Case

I hated having my charging cables tangled and loose in my bag,

so I bought this cable storage case.

It's not only great for organizing charging cables,

but you can also use it as a makeshift phone stand.

When I travel solo, I often find myself eating meals while watching videos,

and it comes in incredibly handy then.

Having tangled cables in my bag used to stress me out,

but this has made things so much neater, and I'm really happy with it!

Nylon Easy-Access Pouch

¥890

This is the nylon pouch that's apparently a huge hit and constantly selling out at Muji Korea.

But I found tons of them at Muji Japan!

The size is perfect, and with three compartments inside,

it's great for keeping small items like hand cream, lip balm, and car keys organized.

I bought it because I can't stand things rolling around loose in my bag,

I ended up losing it, so I didn't get to use it for as long as I hoped. But I was so incredibly satisfied during the few days I had it that I'm definitely planning to buy it again on my next trip!

Cosmetic Refillable Travel Containers

From left: Acrylic Case ¥100, Tube M size ¥150 / S size (pack of 2) ¥120

Since I travel frequently, bringing full-sized skincare products or cosmetics

just makes my luggage too heavy,

These are the mini containers I bought to help lighten my luggage!

They're perfectly sized to fit into the pouches I introduced earlier.

Acrylic Mini Case ~$1 / Tube (Size M) ~$1

While each product has a slightly different purpose,

for me, these sizes are usually enough for a 3-night, 4-day trip, and can even stretch to a 5-night, 6-day adventure.

Dividing your skincare essentials like toner, lotion, and cleanser into these makes packing a breeze and tidying up after your trip so much easier.

Bento Box with Topping Cup 350mL / 450mL

~$4 / ~$4, ~$5 / ~$4

This is the bento box with a topping cup that's been making rounds on social media lately.

It's perfect for packing simple lunches like salads or fruits, and it even has a separate compartment for sauces on top.

If you tried to buy this in Korea but couldn't because it was sold out, you'll find plenty at Muji in Japan, so definitely check it out!

Portable Lint Roller

~$4 / ~$5

This is a portable lint roller.

Its compact size makes it perfect for carrying in your bag, and it's super convenient to pull out and use whenever you need to remove dust or lint from your clothes.

It's especially handy on days you're wearing dark clothes or knits, and it's refillable, so you can keep using it by just replacing the roller.

Mini Ramen: Kimchi Flavor / Chicken Flavor

~$1 / ~$1

These are the Muji mini ramens that are practically selling out everywhere in Korea!

They come in two flavors: chicken and kimchi.

The kimchi flavor suits my palate best, so that's what I usually stock up on.

Just a heads up, they're quite salty, so if you eat a whole one, you might feel a bit bloated the next day. I recommend sharing or eating in smaller portions.

Even just adding hot water worked fine.
