Does this mean tourists don't need a visa for Japan anymore? Including people with traditionally "weaker" passports like Uganda, India, etc.? The article linked elsewhere in the comments is not clear on this.
Probably not. It sounds like they are lifting COVID era restrictions on travel (you could only do pre-arranged tours with strict itineraries)
Probably not. So far, after COVID, Japan is “open” but only if you go as part of a tour group. You can’t just land and get visa-free entry to go backpacking around. It sounds like that’s what’s changing.
If a passport allowed visa-free entry pre-pandemic, this change allows that again. Otherwise you will have to apply for a visa.
