You sound kind of paranoid there bro. It live updates the NA/EU characters too. My guy didn't have that goofy bandit mask before last night.

The servers are just broken all around. Sometimes they work, sometimes they don't, but they're not deleting your data. All of your character information is still stored there. Just because YOU can't load JP servers doesn't mean that no one else can. In fact, JP servers load for me 3x more often than NA/EU.
