What is a randoseru?

The randoseru is the backpack worn by Japanese children from the moment they enter elementary school.
Made of high-resistance leather or synthetic leather, it accompanies the child for six years, without ever being replaced.
Notebooks, books, and toolboxes are protected from daily shocks, day after day.
But it's not just the contents of the bag that are protected.
Designed to protect the growing child's body, the randoseru combines robustness and lightness.
Its design conforms to the shape of the back, for stable and balanced carrying.
Every detail weight distribution, back shape is designed so that the child can wear it,
day after day, for six years, without ever feeling its weight.
Before the start of the school year, choosing its color as a family is part of the joy of preparing for this moment.
For a long time limited to black and red, the choice of colors has now expanded blue, purple, pastel tones offering the child the opportunity to make, for the first time, a choice that reflects them.
For the child, the randoseru alone embodies the anticipation of school life: a true companion, by their side for six years.


It's no coincidence that we manufacture our randoseru in Japan.
Firstly, the region benefits from pure and abundant water
an essential element for material treatment and dye quality.
Furthermore, unlike more extreme climates, Japan enjoys four distinct seasons, with moderate temperature and humidity variations.
This climate stability helps preserve the quality of materials at every stage of manufacturing and storage, throughout the year.
It is in this privileged environment that the expertise of our Japanese artisans has been refined over generations.
From the selection of parts to stitching, reinforcement, and finishing, this expertise is applied at every stage of manufacturing.
Made in Japan




We want every child to grow up happy, in a world where everything they see and touch sparkles and guides them towards the future.
Like a blank canvas ready to welcome all colors, every child holds infinite potential.
We want them to be free to choose their favorite color, and find a color that reflects who they are their own color.
It is with this in mind that we present our randoseru in all colors, in an immaculate space.
Pink and pastel A castle garden
Picking flowers in the gardens of a white castle. Discovering sun-ripened fruit at a city market. Watching hydrangeas bloom behind the window on rainy days. Dreaming of stars on nights when sleep is slow to come.
Navy blue and deep green The youthful knight's drive
Feeling strong, elegant, and brave, like a young knight.
Carrying one's own backpack is already, in a way, feeling oneself grow.
It means moving towards the future with determination, ready to face,
in their own way, the challenges that await them: studies, discoveries, the first steps towards adulthood.
A common emotion for each color
"Dreaming. Hoping. Growing up a little faster."
These emotions, which emerge around the age of five or six, we carry forward into the future: that's why we meticulously attend to every detail, no matter how small, so that the child can intuitively feel it.
A wide range of colors







#POINT01
An ally in an emergency
In Japan, the randoseru is not just a school bag: its rigid structure also makes it an ally in emergencies.
As Japan is a country frequently affected by earthquakes, schools teach protective measures from a young age.
In the event of an earthquake, the learned action is simple: remove the randoseru, place it above your head, and crouch under it to protect yourself from falling objects.
This robustness, originally designed to protect notebooks and books, thus becomes, when needed,
a real protection for the child itself.

#POINT02
Robustness designed to last
The randoseru is designed to withstand intensive daily use for six consecutive years. Every material is carefully chosen high-resistance synthetic leather
and every stitch is reinforced in the most stressed areas: corners, handles, and clasps.
This demand for strength is not just about longevity. It also protects the bag's contents notebooks, books, lunchbox from daily impacts, while accompanying the child as they grow without ever failing.
It is this robustness that allows a randoseru to go through six years of school in the same condition as on the first day.

#POINT03
Designed for the child's comfort
For many years, we have been studying weight distribution and bag shape to protect children's backs and shoulders. Every detail is designed for optimal comfort, day after day.
The back of the bag, which is in direct contact with the child, is made from a breathable material for comfortable wear in all seasons.
