High-level uchigatanas and wakizashi will do okay, but tachis definitely won't. Night battles heavily reduce their stats and they're quite expensive to repair. It's far better to use as many high-level regular tantous for that map if you have them. They're the cheapest and fastest to repair and also perform the strongest in night battles out of all the swords. They do really well there starting from around lv. 60.

At any rate, you definitely don't need to go through the medium or short route to try to get Juzumaru to drop if you don't have enough high level kiwame tantous considering the long route is perfectly viable as well. Just keep trying, even once a day, and he'll definitely drop sooner or later. Then you can use the seals to get another rare sword, if you want, like any of the event-ony ones.
