Yonaka (YO-NAA-KAA) is the Japanese word for
Midnight -- the combination of the two words "YORU" which means
night and NAKA which means the middle.
Technically, Yonaka means "middle of the night" but most
japanese people understand it as late night, usually midnight until about
2:00am.Our full name in Japanese is, Yonaka Hashiri-Ma, which when literally
translated means roughly "middle of the night car racing maniacs".
The term Motorsports is widely understood in Japan
with the same meaning it has in North America.
