Naha City — the capital of Okinawa Prefecture and also the island’s business center — is home to a number of accommodation facilities, eating and drinking establishments, souvenir shops, shopping malls and commercial complexes. Kokusai Street, along with its neighborhoods, is considered Naha’s downtown area. Shuri, with its iconic Shurijo Castle, is the area that thrived as the capital during the Ryukyu Kingdom era. Naha’s Shintoshin, or Omoromachi, area is a popular shopping district dotted with large shopping malls, shops and restaurants, while the Naminoue area offers the only bathing beach in the city, Naminoue Beach. Yui Rail, a monorail running about 13 kilometers across Naha City, from the airport to Shuri, is the only rail transportation system in Okinawa, where no train service is available. Driving time from Naha to Chatan in central Okinawa is about one hour, and it’s about one-and-a-half hours to Nago in northern Okinawa via the Okinawa Expressway.
