In Like a Dragon: Ishin, side quests for side stories are introduced in Chapter Two after Ryoma Sakamoto reaches Kyo via issue #47: Ee Ja Nai Ka. Shortly after visiting the shrine for the first time and discovering Virtue, you will encounter a group of people blocking the way in the northwest corner of Fushimi. However, this is part of a series of side stories involving the right and wrong way to use social protest.
Sub-stories #47: Ee Ja Nai Ka in Like a Dragon: Ishin
This one is quite simple. Heading north from the first shrine of Like a Dragon: Ishin, you’ll see an unavoidable crowd outside of Yashikimachi in northwest Fushimi. Walking towards them will cause Ryoma to interact with them. You will then have to fight a particularly disrespectful party member.
Sub-stories #22: Ee Ja Not Ka en Like a Dragon: Ishin
It’s in chapter 4 of Like a Dragon: Ishin, provided you have completed the previous mission. Head northeast from the Rakugai Blacksmith. (It started for me after finishing The Spitfire Debt Collector.) Walk down the side streets to the bar and Ryoma will start hearing “Ee ja nai ka” again. When you walk in that direction, you will see an old lady on the ground who has been pushed away by the dancers. You will then engage in a fight against the dancers who knocked her down. This will end this sub-story.
Sub-stories #7: Ee Ja Nai for justice in Like a Dragon: Ishin
After completing Side Story 22, you can participate in Ee Ja Nai for Justice. This sees Ryoma clash with a group of dancers protesting against a corrupt official. It’s on Shinmeicho Street in Rakunai, still near the blacksmith. After the Politician tells his guards to attack the mob, Ryoma intervenes. Winning the battle ends the quest.
Like a Dragon: Ishin is available on PS4, PS5, Xbox One, Xbox Series X and PC.
