Kyoto ペットキャリア（オニキス、ラージ）

My 16-pound beagle fits comfortably inside and the carrier slides right under the train seat without any fuss. The padding on the shoulder strap is a lifesaver for longer walks between platforms, and he actually settled down for a nap during our ride.

The mesh windows give my 14-pound cat plenty of airflow, and the padded strap actually makes a 40-minute train ride feel fine. It’s roomy enough for her to turn around but snug enough that she doesn’t get tossed around.

My cat finally rides the train without crying the whole way—the soft-sided design fits perfectly under the seat, and the Onyx color hides fur and dust nicely. It’s roomy enough for her to turn around, and the shoulder strap made the station walk comfortable even with a 10-pound load.
