Meibutsu is a Japanese word that means "famous product" or "specialty". Imagine if you go to a market with your parents and you see a big sign that says "BEST APPLES IN TOWN". These apples might be meibutsu because they are known for being really good and people like to buy them.
In Japan, meibutsu refers to special products that are made in a certain region or city and are famous for being really delicious or unique. For example, in Kyoto there is a special green tea called Uji matcha that is very famous and people from all over Japan love to buy it. It's like a special souvenir that you can only get in that area.
In addition to food and drinks, there are also meibutsu that are famous for being beautiful or well-made. For example, in the city of Arita, there are beautiful ceramic dishes that are known as Arita-yaki. People love to collect them and they are very special.
So, meibutsu is basically something that is famous and special to a certain area or region. It could be food, drink, or even a special item that is handmade or beautiful. It's like a little piece of that area's culture that people love to share and enjoy.
