Not OP, but here's the context surrounding July 5th and Japan.
1. A comic book called "私が見た未来", (roughly translated "The Future I've Seen"), published in 1999, predicted a big earthquake would happen in Japan in 2011, March 11.
2. The big Kanto Earthquake actually fucking happens in Japan on 2011, March 11 as the comic predicted, earthquake, tsunami and nuclear disaster and all.
3. The author of the comic relatively recently, (within the past few years or so), comes out and predicts an even bigger earthquake on 2025, July 5, 04:18 AM. Many Japanese paranormal-themed Youtube channels are still going apeshit over this. <Insert the "2 weeks" meme here>

Picrel is the comic book cover published in 1999. If you look closely, it actually does say "大災害は2011年3月", (roughly translated "Big disaster in March of 2011").
Me personally, I'm guessing nothing will happen. My experience is that when enough people are aware of a future psychic prediction with a specific date and time, somehow the psychic prediction just fails to play out. Feels to me like some hidden rule of the universe or something. I'm still stocking up on food and water and shit though.
