Query all attributes of every Japanese city in the CITY table. The COUNTRYCODE for Japan is JPN.

Alright, let's break this down:

1. First, we need to understand what we're looking for. We want to find all the information (or attributes) about every city in Japan from a table called "CITY".

2. The table "CITY" is like a big spreadsheet that has lots of information about different cities around the world. Each city has a "COUNTRYCODE" that tells us which country it's in. For Japan, the "COUNTRYCODE" is "JPN".

3. So, we need to ask the table to give us all the information about the cities that have "JPN" as their "COUNTRYCODE". This is what we call a "query".

4. To do this, we would use a command that might look something like this: "SELECT * FROM CITY WHERE COUNTRYCODE = 'JPN'". This command is asking the table to select all attributes (that's what the * means) from the cities where the "COUNTRYCODE" is "JPN".

5. Once we run this command, the table will give us all the information it has about every city in Japan. This could include things like the city's name, its population, its area, and any other details that are stored in the table.

So, in simple terms, we're asking the "CITY" table to tell us everything it knows about all the cities in Japan.
