In my effort to answer this I've been trying all the clients I can find and it appears nostr:npub1yzvxlwp7wawed5vgefwfmugvumtp8c8t0etk3g8sky4n0ndvyxesnxrf8q has a built in wallet option like Primal.

I’m curious, is Yakihonne offering a no-kyc custodial lightning account or is this an eCash implementation? It’s not offering backup details when activating the wallet so I’m assuming it’s tied to the npub for recovery but can’t find the docs.
