If your referring to the baggage handling tag that the airline puts on at the airport, the whole tag is a sticky label that can be applied to flat objects like boxes or handle-less suitcases.
The agent should also peel off a smaller “backup tag” and stick it on another area of the luggage. This is in case the main label gets torn off. So make sure you don’t have any old backup tags on your luggage and make sure the agent sticks one on (they often forget).
If you’re really worried, bring some clear packing tape and tape down the edges of your main tag when you check in. But that may be overkill.
Note: some plastic suitcases have a bumpy texture that makes it hard for stickers and tape to stick. In those cases you may indeed want to figure out how to provide a better surface for the luggage tag to stick if there’s nowhere for it to go.
Finally, most checkin agents have used the suitcase pull handle when the carry handle is sketchy.
Also, Japanese delivery companies are really good in terms of compensation. I’d honestly just get a new suitcase and bill them.
