People who want to leave or enter Inazuma legally must pass the strict assessments conducted by the Kanjou Commission to obtain permission. Those who are not Inazuman cannot leave Ritou without a Travel Permit as a result. However, such restrictions did not initially apply to the Fatui and Snezhnayan merchants due to their diplomatic ties.
To enforce the Sakoku Decree, the Shogun surrounded Inazuma with a storm barrier, resulting in very few ships being able or willing to navigate them and harm Inazuma's economy. The storm barrier is encountered in-game as A Nation Closed by Thunder and prevents players from entering Inazuma before the quest Setting Sail (Archon Quest Chapter II Act I: The Immovable God and the Eternal Euthymia) as well as traveling to and from Inazuma without teleportation, such as with Teleport Waypoints.
When the Vision Hunt Decree was abolished, the Sakoku Decree had not immediately followed suit. However, the restrictions placed upon foreigners were relaxed and the decree was expected to be lifted soon after. After her duel against the Shogun in Imperatrix Umbrosa Chapter Act II: Transient Dreams, Ei abolishes the Sakoku Decree, resulting in an influx of visitors and foreign trade returning to normal.
- "Sakoku" (Japanese: 鎖国) means "the locking up of a country" in Japanese, and has been translated as "closed" or "state of lockdown."
