The Weight of an Ita-bag Witnessed in the General Admission Queue at Wonder Festival
In the middle of the general admission queue at Wonder Festival Summer 2019, the ita-bag of the attendee in front of me was slowly tilting. Inside the transparent PVC window, can badges of the same character were packed tightly. There must have been well over 60. The spot where the shoulder strap dug in had turned red, and every five minutes they shifted the bag to the opposite shoulder. The wait time was 40 minutes. Even while touring the dealer booths after entry, that bag would continue hanging from their shoulder.
Oshi-katsu merchandise culture appears light and glamorous in social media proof shots. But on-site, only one's own shoulders and wallet bear that weight. The number of can badges contained in a single ita-bag averages 30-50, with weight ranging from 800g to 1.5kg. When acrylic stands are added, cases exceeding 2kg are common. Unlike scale figures fixed inside glass display cabinets, the physicality of merchandise worn on the body daily is heavier than expected and wears out faster than expected.
Let me state my conclusion first. Ita-bags are not the pinnacle of oshi-katsu but its beginning. When you attach that first can badge, it feels light, but only after filling in 42 do you realize: what this culture demands is not just affection, but shoulder endurance and wallet stamina.
What Is the Physical Weight of 42 Can Badges?
A single standard 75mm diameter can badge weighs approximately 22g. The 57mm version is about 15g, and 44mm around 10g. Calculating 42 at the 75mm standard yields 924g, approaching nearly 1kg. Add to this the ita-bag body itself (averaging 250-350g with transparent window), decorative backing sheet (50g), chain ornaments and acrylic keychains (100-150g total), and you reach 1.3-1.5kg. It's equivalent to carrying three 500ml plastic bottles on your shoulder.
The problem is not the weight itself but its distribution. While figure boxes are carried by hand or received by delivery, with ita-bags the entire load concentrates on two shoulder straps. When the strap width is 2cm, a 1.4kg bag exerts approximately 700g/cm² of pressure on the shoulder contact surface. Carry it for over 30 minutes and strap marks remain; after 2 hours, shoulder muscles ache. Most ita-bag proof shots uploaded to social media are photographed either held by hand or placed flat. Only those who've carried one all day long truly know: the weight remembered by the shoulder points in the exact opposite direction from the glamour in photographs.
Ita-bags filled with over 40 can badges mostly transition to display-only use at home. Actual-use ita-bags typically compromise at an average of 15-25 badges. The process of finding the balance point between weight and practicality is precisely the maturation curve of oshi-katsu.
Why Does Oshi-katsu Merchandise Start Light and End Heavy?
When you buy that first can badge, it feels light. Between 700-1,200 yen, it starts with the feeling of spinning a gachapon once. The second is the same character in a different outfit, the third activates the series completion desire. Around the sixth, you think, "Since I'm collecting anyway, why not make an ita-bag?" Purchase of the ita-bag body (20,000-40,000 yen), addition of decorative sheets and chains (10,000-20,000 yen), and subsequent purchase of additional can badges to fill empty spaces follow.
The problem is that can badges aren't sold individually. Most are random box sales or event-limited/bonus gift formats. To obtain one desired character, you buy a box (6-12 piece sets), and put duplicates and unwanted characters up on secondhand trading platforms. Average box price is 15,000-25,000 yen. Spin through three boxes and you've already exceeded 70,000 yen. Community statistics showing an average of 100,000-150,000 yen to complete one ita-bag are no exaggeration.
Acrylic stands are more brutal. H150mm and larger products cost 12,000-20,000 yen each, and limited editions exceed 30,000 yen. Just buying one main acrylic stand to place in the center back of the ita-bag and two for left-right auxiliary placement costs 50,000-60,000 yen. It's the moment when oshi-katsu that started lightly becomes a hobby with monthly expenditures of 150,000 yen. Weight is borne by the shoulder, but wallet weight returns as bank balance.

Ita-bag photos uploaded to social media are mostly frontal flat compositions. Can badges filling the transparent window sparkle in the light. Likes reach 300, with comments lined with "pretty," "perfect," "envious." But three things are missing from those photos: marks where shoulder straps dug in, dust accumulated at the bag bottom, and holes where safety pins on the backs of can badges pierced through fabric.
Ita-bags are not display frames. The moment you carry them, physical laws operate. With each step, can badges shake, and safety pin fasteners gradually stretch the fabric. After 3 months of use, the fabric around window edges loosens, and after 6 months, some can badges fall out. Safety pin locking mechanisms loosening is not manufacturing defect but the inevitability of repeated use. Though it doesn't appear in proof shots, average ita-bag lifespan is 1 year. Many who carry them daily replace them every 6 months.
Separating photography-use from actual-use is the choice of oshi-katsu veterans. Photography ita-bags remain at home for combined display and photography purposes, while going-out ita-bags are configured lightly with 10 or fewer can badges. Preparing both costs approximately 200,000 yen. Behind one perfect photo uploaded to social media hides the logic of dual operations working in invisible places.
Does a Golden Ratio for Ita-bag Decoration Exist?
The golden ratio circulated in communities is "20 75mm can badges + 10 57mm + 1 H120mm acrylic stand." Total weight is approximately 800g, the upper limit for carrying comfortably on shoulders. However, ita-bags adhering to this ratio receive evaluations on social media like "still not full" or "the empty space is disappointing." Proof shot culture favors densely filled coverage without gaps.
To increase density, you either fill empty spaces with 44mm small badges or add chain ornaments and ribbons. However, while 44mm badges weigh 15g each, adding 10 adds 150g, and chains and ribbons add another 100g. It's the moment you exceed 1kg from the golden ratio's 800g. Practicality collapses, leaving only display use.
Some oshi-katsu users operate a "rotation system." They change can badge arrangement weekly and switch themes according to seasons or events. With a single ita-bag, they rotate through 80 owned can badges. Weight remains constant while proof shots with different configurations can be uploaded to social media each time. The golden ratio existed not in numbers but in operational method.

"Ita-bag bulk transfer" posts appear weekly on secondhand trading platforms. Most cite reasons like "graduating from oshi," "taste change," or "lack of storage space." But the real reasons emerge in comments: "heavier than expected," "can't handle monthly expenses," "compulsion to buy whenever new merchandise comes out."
Unlike figure collecting, oshi-katsu has no visible end. Scale figures have set release schedules, and choices end at around 2-5 types per character. But can badges and acrylic stands see new designs every month. Birthday commemoratives, event exclusives, collaboration bonuses, seasonal outfits—30-50+ merchandise items for a single character annually is not uncommon. Buying everything is impossible; choosing is agonizing.
The confession "at first I bought because I liked it, but at some point I bought from a sense of obligation" appears frequently in communities. It's the point where oshi-katsu transforms from expression of affection to consumption competition. The pressure created by ita-bag proof shot culture accumulates outside social media as fatigue of shoulders and wallet. What people who quit transfer is not just merchandise. They also hand over memories of weight they couldn't bear.

Figure collecting and oshi-katsu merchandise culture belong to the same otaku cultural sphere, but their operational methods are polar opposites. Figures appreciate or maintain value after release, but can badges plummet in value immediately after events end. Even limited edition can badges trade at 50% or less of retail price in the secondhand market 3 months later. Having no resale value means spending purely for personal satisfaction alone.
Figures inside glass cabinets remain in place even 10 years later. But can badges in ita-bags—you can barely remember where they went after 1 year. Badges with fallen safety pins pile in drawer corners, faded acrylic stands stack in boxes. As the lifespan of physicality is short, emotional consumption is also rapid. Figures are collection, merchandise is consumption. Both open wallets, but what remains differs.
Therefore, some collectors don't pursue both cultures simultaneously. If focusing on figures, merchandise is kept to a minimum; if immersed in merchandise, figures are left untouched. Budget, space, and emotional capacity are limited. Whichever you choose, you alone bear the weight.
FAQ
What's an appropriate budget when first starting an ita-bag?
Combining the ita-bag body (20,000-40,000 yen), 15-20 can badges (including box purchases, approximately 50,000-80,000 yen), and decorative sheets and chains (10,000-20,000 yen), you start at a minimum of 80,000 yen. Adding acrylic stands brings it to 120,000-150,000 yen. Rather than trying to complete it all at once, filling it gradually over 3 months is the method that reduces wallet burden.
Safety pins on can badges keep coming loose—how do I manage this?
Safety pin locking mechanisms naturally loosen after 3+ months of use. You can slightly tighten the locking ring with pliers or add another layer of fixation on the back with clear tape. However, there's no fundamental solution. For frequently carried ita-bags, the realistic approach is to rotate can badge arrangements every 6 months to 1 year, or simply separate display-use from actual-use entirely.
I want to quit oshi-katsu merchandise—how do I organize it?
Bulk transfer on secondhand trading platforms is fastest. However, note that can badges trade at 30-50% of retail and acrylic stands at 50-70%. Some high-value limited editions or popular characters may sell close to retail, but most require accepting losses. If affection has cooled, quick disposal is better. The longer you wait, the more market value drops.
If doing both ita-bags and figure collecting, how should I allocate budget?
Assuming 30% of monthly disposable income goes to hobbies, allocating figures and merchandise at 7:3 or 8:2 is typical. Since figures maintain resale value while merchandise is consumption-heavy, increasing the figure proportion long-term is advantageous from an asset management perspective. For merchandise, developing the habit of deciding "just one thing I absolutely want to buy this month" to reduce impulse purchases is necessary. Both cultures are endless, so you must draw your own boundary lines.
---
What I realized after filling 42 into an ita-bag is that oshi-katsu is not proof of affection but a choice of weight. Weight shoulders can bear, speed wallets can sustain, and density hearts can endure. The process of finding the balance point among those three is each person's own oshi-katsu. Social media proof shots are glamorous, but on-site, you alone shoulder that weight. May good connections reach your glass display cabinets today as well.
