Regional Features of Southern California

Home to Los Angeles and San Diego, Southern California is a beautiful area coveted by people worldwide, symbolized by blue skies, the sea, palm trees, and the shining sun. The number of Japanese companies and residents is among the largest in the U.S., and has a well-established infrastructure as convenient as Japan’s. The food culture is highly diverse; you can enjoy authentic Mexican food, the sushi culture of the region that birthed the California Roll, and gourmet flavors from around the world. Locally founded hamburger chains, in particular, are immensely popular as a West Coast classic. With Hollywood (the capital of film), Disneyland, and the beaches of Santa Monica, there is no shortage of weekend activities. The climate is a Mediterranean one that remains warm year-round, with low humidity making it very comfortable. While the cost of living is high, it is more than offset by the abundance of exciting experiences and career opportunities. For those who want to embody the "California Dream", fulfilling both professional and private life in an open atmosphere where diverse cultures mix, this is the perfect destination.
