One week before my trip, I ordered two TRIWONDER foldable duffel bags on Amazon Japan (Model: 01 A, Color: Black).
Each one was ¥2,290.
Originally, I planned to buy just one.
But then I remembered my sister’s legendary shopping power — so I bought two without hesitation 😂
One was used every day to bring all our shopping back to the hotel, and the other became our extra luggage for the return flight.
And of course, we really ended up needing it — no surprise at all! hahaha
Even though I personally feel I didn’t buy that much on this trip 😌, this foldable travel bag turned out to be the most valuable thing I brought with me.
👜 Why I love this bag
The shoulder strap is wide, so it doesn’t dig into your shoulder at all.
The double-zipper design feels very secure, and you can even put a small lock on it if needed.
During the trip, I almost never used store shopping bags — everything just went straight into this duffel bag.
I don’t like carrying a bunch of bags in my hands, so having a bag that can be both hand-carried and shoulder-carried is a lifesaver, especially when walking long distances.
The shoulder strap length is perfect — even for someone like me with a bigger build, it doesn’t cut into the underarm area (if you know, you know 😆).
When folded, the size is about the same as a 500ml water bottle.
That’s slightly bigger than some ultralight foldable bags, but the fabric is thicker, the structure stands up firmly when packed, and it keeps a nice shape — so for me, this is totally worth it.
Inside, there are small organizing pockets around the inner wall, perfect for separating small items without needing extra pouches — very convenient!
And the best part: it can be securely attached to the suitcase handle, so you don’t have to carry it by hand — super effortless when moving through airports or train stations.
If you’re looking for a foldable travel bag that’s lightweight, comfortable to carry, durable, and stands firmly on top of your suitcase, I truly recommend this one.
