How do you say hello in Edo?

There isn't a specific phrase for "hello" in Edo specifically. Edo was the old name for Tokyo, and people in Edo spoke a dialect of Japanese known as Edo-kotoba. While there were some regional differences in pronunciation and vocabulary, the basic greetings were the same as modern Japanese:

* Konnichiwa (こんにちは) - Good day / hello, used during the day.

* Ohayou gozaimasu (おはようございます) - Good morning.

* Konbanwa (こんばんは) - Good evening.

It's worth noting that while "Konnichiwa" is the most common way to say "hello" in modern Japanese, it was actually considered a more formal greeting in Edo-kotoba.

If you're interested in learning more about Edo-kotoba, you can find resources online and in libraries. However, it's important to remember that it's a dialect that is no longer actively spoken, and modern Japanese speakers would understand standard Japanese greetings just fine.
