Series of mods that I am using in my Jozai Legendary campaign in FOTS.
I am still testing things like the launch order a bit, I chose only these few mods to guarantee it won't crash. There are more that I like, which you can check on my other collections.
If you are having issues, follow these steps:

1. Launch the game WITHOUT any mods
2. Launch the game again and select the mods from Lost Domains to below
3. Launch the game with the rest of the mods

Also: The additional years mod and the increased zone of control mod crash the game, I think it's because Lost Domains alters the same files.

List of mods as it appears on the launch window:

The Hayashi Clan of the Jozai Domain is really interesting both lore and gameplay wise. The Hayashi clan was one of the first to come into contact with Commodore Matthew Perry and the American fleet. Their Jozai Domain had a strategic position in controlling Edo's (Tokyo's) Bay and these things allowed this minor and somewhat poor clan to get good positions in the bakufu. Their daimyo during the Boshin War, whose picture you can see above, was called Hayashi Tadataka, aged only 19 years old at the time. He wasn't part of the Shogunate loss at the Battle of Toba–Fushimi, but once he received news of it and of the Shogun having fled Central Japan, Hayashi took his entire army up north of Japan to fight as part of the Ōuetsu Reppan Dōmei, an alliance of the northernmost domains of Mutsu, Dewa, and Echigo. During this time the Hayashi army performed guerrilla actions all the way into Sendai.

Hayashi Tadataka, also known as Masanosuke, was amongst those that fought for the Shogunate until the end, he only surrended once he received news that the Tokugawa were going to be given a domain and power in the new Imperial order. However, having fought so fiercely when others stood down, the Hayashi Clan was stripped of the Jozai Domain and Tadataka was detained at Edo. Eventually, he was released, and held several government positions, being made a danshaku in the kazoku system (something like a baron and one of the lowest hereditary peer titles in the Imperial order). Hayashi Tadataka was the last of the former daimyōs to die, living until 22 of January in 1941, at the ripe old age of 92.

Today the Jozai Domain is a part of Chiba's prefecture, where the National Museum of Japanese History is located. I personally like archives more, due to my current university studies into the area, so I should also mention the Chiba Prefectural Archives and the local archives, which respect the provenience principle, holding several rare documents and materials from across the prefecture, preserving the administrative and cultural history of Chiba Prefecture, according to the idea of primary and secondary values respectively.

Gameplaywise, I like their blue and black colour scheme, I only wish the blue was darker like in Satsuma's (Shimazu's) case. Plus, their unique traits and unit allows them to be really aggressive. You can send your army into enemy territory for most of the year and they will replenish while there. Their Yukigetai unit is an improved sharpshooter as well, which helps you to set up ambushes and use sneaky tactics. Overall, their position is also quite good, you don't have your back to the wall in any way, you start close to Edo (Musashi) and you can decide your path fairly well, having the US trade node really close also helps your trade.

The only possible issue is that you can trigger realm divide easily if you blitz the enemy and find yourself with enemies on all sides, something which the Aizu and Satsuma avoid by having the possibility of pacifying all enemies in one direction before it happens. Still, if you are running a Shogunate run, you might get lucky if the closest factions don't end up Imperial, thus making realm divide a guarantee that they won't betray you. The only case when it won't work is if you go republican, which I consider more fun anyway but means you enter total war with all other clans like in the case of the regular Shogun 2's realm divide.
