Okinawa is a subtropical climate that is warm in winter and cool in summer, and is suitable for vacation all year round. April to October: For the summer of Okinawa, enjoy a sea bath in this long period. May to June: During the rainy season, the rain is hot and stuffy, and the rain falls around June 20 and then enters the summer. The summer is dominated by sunny days and the sun is strong. September to November: Sometimes a typhoon hits. November: Mainly cloudy and light rain, a short winter is coming. Winter (November to March) is very warm, basically kept at around 20 °C, no snow. What do you want to take to Okinawa? Clothing: I won't say it in the summer. The temperature in winter is generally around 18-26 degrees, a little cold, long-sleeved outerwear + jeans ok. If you want to be beautiful, you can consider wearing a thick skirt. It is recommended to wear a long-sleeved jacket even in the summer, because the air conditioner is turned on everywhere (the winter is also open). Sunscreen: Be sure to bring it, it is very dry. Umbrella: Free rental umbrellas are available in hotels or other public places, where it always rains. Rain is usually a shower. Take it as appropriate. The sun protection function of my umbrella is more important. Drugs: General fever, cold medicine can be. Power adapter: If you bring a computer (recommended) or other electrical appliances, the plug is three-socket, it is best to buy two heads and three heads. There are two plugs on the other side of Japan, and there are very few three plugs (American standard, the plug above is cylindrical). The hotel I stayed at (Pacific Hotel Pacific Hotel) didn't have three plugs. I bought the wrong converter and rented a converter at the hotel. The 1000 yen deposit was used up and the refund was used. If you don't buy it in China, there is only one small shop selling goods in the international terminal of Naha Airport, 630 yen. Mobile: I only know mobile. The global sensation zone, Shenzhouxing, and the 5-card card can open permanent international roaming for free. The balance is to be 500 and the real name system. If you only have one month of roaming, the balance will be 200. Direct 10086 has been opened for real-name system (or text message KTGM to 10086), and there is no real-name system to go to the business office. After that, you must ensure that your mobile phone must support WCDMA (3G standard), because Japan is a 3G signal (Docomo or Softbank) to roam the past. After roaming, the direct domestic call is 4.99rmb/min and the SMS is 0.89rmb/strip. If you dial ** 139 * 86 mobile phone number # can be 1.99rmb / minute. Before going, it is recommended to suspend the Internet function and send ZTSJLL to suspend the Internet service. After returning to China, HFSJLL will resume again. Cameras, etc.: In principle, more than 5,000 personal items must be declared at the time of customs clearance. I am very embarrassed to declare, and the result is no one at all, sigh~ do not report in Japan. Kettle: It's very important! ! Japan buys water and is expensive... a bottle of mineral water on the street costs 110 yen or more. Therefore, the daily activity hotel will pick up the water with the water at the tourist attraction. As for drinking hot water, the hotel I live in offers a boiling water cup and can boil water by myself. But eating outside is free to ice water because of westernization.. Toiletries: The hotels I live in offer Shiseido's shampoo and facial cleanser. I bring the slag. Girls need to bring skin care products, remember to check. The hotel has only woolen slippers, the bath is a bathtub, and the bare feet can stand without plastic slippers. JPY: The bank only offers a large face value exchange of more than 1,000 yen. If you go directly to the exchange, it is generally only 10,000 yen. To 1000 yen, you need to make an appointment one day in advance. However, it is recommended to change the number of 1000. (Note: The yen is below 1000 yen.) Local convenience stores and the like will help to exchange small change, the service is very good. The yen exchange rate has been rising, so it is better to exchange money in advance. Language: It is good to speak Japanese. But English is also OK, hotels and other tourist areas can basically communicate easily.
