Your best bet is to put all of your strongest swords (include kiwame) into one single team or if you have enough, more teams. Then spam E4 as much as you can. I don't recommend using tachi, uchigatana, wakizashi and yari because they lack the night boost and speed of tantous while also lacking the tanking ability and range of ootachi/naginata (although Iwa seems high enough to withstand it). Unless they're about 90+, which'll counter any debuffs they receive at night.

Unless you're strong enough/have enough rations, don't try the chaos maps. It's also best to use your gold box on the hardest map you can complete because it ensures that you won't lose the box and you'll get the bonus. I've had a lot of success using two kiwame tantou (35+) + two standard tantou (90) + two ootachi (99) on E4. It's also best to use your batons on the chaos maps.

Assuming you get about roughly 450 otos per run of E4, your current amount of koban will get you 36900 otos and that's nowhere near enough for Hyug. So from there you'd have to supplement your koban count with expeditions. If you're not going to use other teams, it's best to send them off on expeditions that'll give you koban. The expeditions article on this wiki will give you an indicator of what is the best.

TL;Dr: Put your most powerful into a team, do more expeditions for money (check the wiki for a guide) and do the hardest maps that you can consistently finish.

Good luck!
