いきなりだんご is a local dish in Kumamoto Prefecture, Kyushu. "Ikinari" means "suddenly", it is described as that because it is often made when visits suddenly appear at your house.
The world kimono literally means "clothing", and is the most recognizable garment from the Japanese culture - even not being the most used anymore.
During the Meiji period (September 8, 1868 - July 30, 1912; when Japan moved out from being a feudal society), the western culture and fashion started to get imported and became more popular; kimonos now are more expensive and used only in special occasions.
Due to this, many people nowadays won't know how to properly put and tie a kimono (since it's a complicated procedure), having to ask help for their mothers or take a course at a kimono school.
A kimono has a lot of different parts:
Front
Rear
