United States

If you want to find out more about American etiquette, feel free to read Emily Post. This lady has published a wonderful book describing what is considered to be a norm in the United States. The book will teach you how to behave in the country and what to expect from the people surrounding you there. According to Emily, the wisest way to welcome new people is to bring them a bouquet. Also, a plate of home-made cookies will also be appreciated! It is very probable that you’ll be informed about the rules set by the local authorities. Some will show up at your door with something quite practical, such as takeout menus from their favorite local bars and restaurants.

Japan 

Neighborly relations in Japan are totally different from those observed elsewhere. They are very delicate and polite. If you have kids, let them visit the neighbors and deliver some small gifts. Try and make the gift tiny since impressive presents will only make the people feel uncomfortable and embarrassed.
