Before arrival, mark two locker or staffed-storage candidates on JR West’s Shin-Osaka map and make your hotel the third option. An official facility symbol does not guarantee an empty compartment large enough for your suitcase. Save the collection deadline and the route back from Osaka Metro together with the storage location.
After leaving the Shinkansen, the emotional impulse is to reach the tournament quickly. Carrying a large case to Namba and the arena, however, makes the subway crowd, seat space and evening exit harder. Ten deliberate minutes at the beginning can simplify the next several hours.
Build two candidates from the map
JR West’s station information identifies coin lockers, a baggage service, gates and lifts. Put the first candidate along your natural route from the Shinkansen toward Osaka Metro. Put the second on another level or near a different gate, not directly beside the first bank of lockers. Confirm size, operating period and accepted payment on the physical display.
A staffed counter has a collection deadline. If you plan to return after the final bout, do not aim for the last possible minute. Add the Namba crowd, subway journey, walk through Shin-Osaka and a queue at the counter before your onward train.
If both are full, do not transfer the problem to the arena
Return to the hotel-storage option, find a currently operating official reservation service, or stop the bag at another station already on your route. A service appearing in search does not establish that it is open or has capacity. Check the operator’s current information.
Luggage forwarding to a later hotel can remove the case for more than one day. Confirm that the receiving property accepts deliveries and allow the stated transport interval. Keep your passport, medicine, ticket access, electronics and anything required the next morning with you.
Photograph the return path
Record the locker number, floor, nearby shop or gate and whether it is inside or outside a ticketed area. A photograph of the approach is more useful than a close-up of the door. Returning from Namba, you should be able to tell which side of the Shinkansen gates holds the bag.
Once your shoulders are light, watch one wrestler’s foot survive the edge of the dohyo. There is a pleasing contrast between releasing your own weight and noticing exactly where a rikishi keeps his.
Evidence limits and event-day fallback
Confirmed fact: JR West station information/maps and the Osaka Metro station page identify gates and facility candidates. A map symbol does not show that this bag fits now.
What remains unknown: Vacancy, internal dimensions, price, payment, hours, staffed-desk queue, the live inside/outside-gate route and hotel acceptance remain unknown for the date and bag.
Reasoned inference: Saving storage and retrieval as one route is likely to reduce post-sumo mistakes. Confidence is medium; it does not guarantee collection or the train connection.
Editorial suggestion: Record the level, gate and nearby landmark and avoid a closing-time retrieval. This is not an official station or storage procedure.
Fallback: If both candidates are full or unsuitable, move to a confirmed hotel, other station or formal service. Do not make carrying a large case into the arena the automatic third option.
