2026SS Season
Material Update: From Quilted Construction to Matte Leather
The highly popular Cake Bag, which also appeared in the 2026SS season.
There is a major update for the 2026SS season.
While it was released in a quilted construction in 25SS and 25–26AW, the 26SS season sees an update to matte leather.
The matte leather, characterized by its subdued, calm texture, develops a richer depth and a soft sheen over time as the oils gradually absorb, allowing you to enjoy its aging process.
The overall impression changes dramatically compared to the quilted version, so we highly recommend experiencing it in person at the store.
Detail Update: From Silver to Gold
The round rivets, which were silver up through 25AW since the initial release, have been updated to gold.
Additionally, a chain that was not included in 25SS and 25AW is now added for the 26SS season.
This chain also comes in a gold finish.
The combination of matte leather and gold accents elevates the bag to a jewelry-like presence.
The chain is designed in a shorter length, allowing for both shoulder carry and hand carry.
Compared to 24AW, the chain is noticeably slimmer.
The pairing of matte leather and gold feels refined rather than excessive, resulting in a luxurious finish.
Mini Size for Accessory-Like Styling
Following 25AW, the mini size is also available for the 26SS season.
The mini size, like the regular size, comes with a chain.
Unlike the 25AW version, which was designed to be attached to belt loops or bags, the addition of the chain allows it to be used like a mini bag.
The chain and rivets are finished in gold.
The color variations are the same four colors as the regular size.
Available colors
・Black
・Chocolate
・Green
・Cream

CAKE BAG 26SS Styling
2025AW Season
A Standard Size That Becomes the Centerpiece of Your Look
In the 2025AW season, the standard size is reintroduced in both quilted and foil-finished versions.
It is available in four colors: Black, Brown, Silver, and Gold, making it ideal as an accent piece for your styling.
As no chain is included, you can enjoy pairing it with a chain of your choice.
PETIT Size for Accessory-Like Use
In the 25AW season, the PETIT size was newly added to the lineup.
The PETIT size is compact enough to be attached to a belt loop, combining practical storage for small essentials with a playful, metaphorical concept inspired by “dreams and sweets.”
You can attach it to your existing bag or a CAKE BAG to enjoy a variety of styling arrangements.
As the capacity is limited, it is best recommended for use as an accessory.
Simple Yet Striking Design
The standard size features an expanded quilted surface, creating more sculptural depth and shadow.
Instead of traditional stitching, the bag is shaped solely with round studs, and the large circular rivets add a powerful accent to the otherwise minimal design.
The PETIT size fits comfortably in the palm of the hand, bringing a charming and feminine touch to any outfit.
A Design Completed Through Customization
The magnetic handle provides a satisfying click when opening and closing.
A large O-ring is attached to the side.
You can attach a chain or your preferred strap to customize the bag into a truly one-of-a-kind piece.
At our store, pairing it with a KAMIYA wallet chain has been especially well received.
A three-dimensional brand logo is applied to the surface.
Durability and Expression Created by Cow Leather × Foil Finish
The material is the same as used in the 2025SS season, featuring cow leather finished with a foil coating.
The inherent durability of cow leather ensures long-lasting use.
As the bag is used over time, the foil on the quilted surface develops fine abrasions, gradually maturing into a calmer, more subdued sheen.
Prices by Size
・Standard ¥60,500 (tax included)
・PETIT ¥49,500 (tax included)
2025SS Season
In the 2025SS season, the Mini size of the CAKE BAG was updated.
With two material variations—glossy cow leather embossed with a quilted pattern, and metallic leather finished with foil—the design gains added visual depth and playfulness.
While retaining its structural beauty defined by seamless construction, round studs, and a magnetic handle, the three-dimensional pattern reflects light from multiple angles, enhancing its presence.
Available in three colors—Black, Brown, and Silver—the lineup ensures versatility and ease of integration into everyday styling.
A chain is not included; instead, a studded belt was released as a separate option.
The brand’s approach of “recontextualization,” described as “something you feel you’ve seen before, yet looks new,” becomes more clearly expressed this season through the refreshed materials.
A Refined Accent Created by Gloss and Metallic Finishes
The round studs resonate with the grid-like embossed pattern, creating complex shadows and a naturally rich expression.
The design is minimalist, composed solely of the brand logo and round studs, with all unnecessary details removed.
This restrained detailing allows the quilting to stand out without interference, resulting in a harmonious overall appearance.
A Minimal Design Stripped of Excess
The round studs overlap with the grid-style embossing, generating intricate shadows that give the entire bag a natural, expressive look.
With no superfluous details, the design remains purely minimal, consisting only of the brand logo and round studs.
This minimal detailing elevates the item into a balanced piece that does not detract from the quilting.
Leather That Lets You Enjoy Two Expressions: Gloss and Foil
Both the glossy cow leather and the foil-finished leather offer excellent durability, allowing their solid texture to be enjoyed over time.
As the quilted foil surface is used, fine abrasions gradually appear, settling into a subtle, refined sheen with age.

2024AW Season
The CAKE BAG first made its debut in the 24AW season.
The initial release of the CAKE BAG dates back to the 2024AW season.
It was offered in two sizes, Standard and Mini, with a color scheme based on black accented by white.
Designer Shinpei Goto has stated that he wants “wrinkles, scratches, and even stains to become memories,” proposing a relationship in which the owner and the bag share a story through aging and use.
A Distinctive Design Inspired by a Cake Box
Based on the square form of a cake box, the design features softened lines with rounded corners that leave a gentle impression.
The round studs serve both as functional elements and iconic decoration, creating a visual rhythm.
The Essence of Design Found in the Details
The handle contains an embedded magnet, allowing smooth one-handed opening and closing.
The experience of the handle snapping neatly together through magnetic force evokes the excitement of opening a gift in everyday life.
A three-dimensional brand logo is applied to the front.
The included chain strap combines a rugged texture for practicality with chandelier-like parts that shimmer like raindrops, embodying harmony between contrasting elements.
A Structure That Maximizes the Natural Appeal of Leather
Glossy natural cow leather is used.
The structure, formed from a single piece of glossy cow leather and shaped solely with round studs without stitching, achieves a sculptural presence despite its minimalism.
With continued use, the leather deepens in color, allowing you to enjoy its aging process.
Prices by Size
Standard ¥68,200 (tax included)
Mini ¥55,000 (tax included)

What Is the CAKE BAG? From Concept to Size and How to Use It
The core concept of this bag is “to allow people to experience, in everyday life, the sense of happiness many feel when carrying a cake box.”
The excitement and anticipation associated with cakes—symbols of special moments such as birthdays and anniversaries—have been translated into the form of a bag, so they can be carried and enjoyed at any time.
Designer Shinpei Goto views fashion as something that “enriches and brings joy to daily life and to one’s entire life,” and the CAKE BAG is the purest embodiment of that philosophy.
This universal concept was inspired by a single scene witnessed by Goto.
On a rainy day, he saw a man—presumably a father—walking carefully while cradling a cake box so it would not get wet.
In that gentle gesture of protecting something precious, Goto found meaning beyond the ordinary, saying that he “saw a hero” in that moment.
This inspiration is deeply connected to the image of masculinity that MASU continues to explore.
The Standard size can hold a wallet, smartphone, and a 500 mL plastic bottle.
The Mini is an everyday size designed to carry only essential items in a sleek, streamlined way.
The PETIT size is ideal for small items such as AirPods or lip balm, and can be enjoyed like a charm attached to a belt loop or another bag.
When worn crossbody with the chain strap, it keeps both hands free, making it perfect for strolling around the city on days off.
Standing the handle upright and carrying it like a clutch complements formal outfits as well, drawing attention at dinners or parties.
The greatest appeal lies in embracing aging without fear—allowing scratches to become memories and cultivating the bag into a one-of-a-kind vintage piece over time.
