Follow the safe-diving basics<\/h3>\n\n<ul>\n  <li><strong>Do what the guide signals.<\/strong> Okinawa&#8217;s underwater topography is complex and currents shift; never move forward, back or up on your own judgement.<\/li>\n  <li><strong>Never dive alone.<\/strong> Stick to the buddy system and keep your partner and guide in sight at all times.<\/li>\n  <li><strong>Ascend slowly.<\/strong> A fast ascent expands nitrogen bubbles in the body and can cause decompression sickness or lung barotrauma. Coming up from depth, make a <strong>safety stop of at least three minutes at five metres<\/strong>.<\/li>\n<\/ul>\n\n<h3 id='5-read-the-cancellation-policy-before-you-pay'  id=\"boomdevs_24\" class=\"main-head\" >5. Read the cancellation policy before you pay<\/h3>\n\n<p>Typhoons are frequent from summer into autumn, particularly August to October. If a shop calls off a trip because of sea conditions, the standard remedy is a <strong>full refund or a free reschedule<\/strong>.<\/p>\n\n<p>Cancelling for your own reasons is a different matter and usually follows a sliding scale \u2014 free up to eight days out, a rising percentage inside seven days, and 100% on the day. Terms vary by operator, so read them at the point of booking.<\/p>\n\n<h3 id='6-dive-lightly-on-the-reef'  id=\"boomdevs_25\" class=\"main-head\" >6. Dive lightly on the reef<\/h3>\n\n<ul>\n  <li>Do not touch or stand on coral, and do not chase or handle marine life.<\/li>\n  <li>Do not feed the fish \u2014 bread and pellets disrupt the local balance.<\/li>\n  <li><strong>Choose your sunscreen carefully.<\/strong> Chemical filters such as oxybenzone contribute to coral bleaching. Use a product labelled reef-safe, or skip it altogether and cover up with a rash guard or wetsuit, which works better anyway.<\/li>\n<\/ul>\n\n<hr \/>\n\n<h2 id='faq'  id=\"boomdevs_26\" class=\"main-head\" >FAQ<\/h2>\n\n<p><strong>Q. Do I need a diving certification in Okinawa?<\/strong><br \/>\nNot for snorkelling or discover scuba diving. A discover scuba dive takes you to 12 metres with an instructor alongside you the whole time and no card required. Only fun diving below 18 metres requires PADI Open Water or Advanced Open Water certification.<\/p>\n\n<p><strong>Q. How much does diving in Okinawa cost?<\/strong><br \/>\nSnorkelling is \u00a54,000\u20138,000, discover scuba \u00a58,000\u201320,000 and guided fun diving \u00a515,000\u201325,000. Boat access to an offshore site adds roughly \u00a52,000\u20135,000 on top.<\/p>\n\n<p><strong>Q. How long after diving can I fly?<\/strong><br \/>\nWait 18 to 24 hours after any dive on a tank. Nitrogen absorbed underwater expands at cabin altitude and can cause decompression sickness, so you cannot dive on your departure day. Snorkelling has no waiting period.<\/p>\n\n<p><strong>Q. Can I dive in Okinawa if I cannot swim?<\/strong><br \/>\nYes for snorkelling \u2014 you wear a buoyancy vest and float on the surface. Discover scuba is also possible because the instructor manages your buoyancy, but tell the shop when you book if putting your face in the water makes you uncomfortable.<\/p>\n\n<p><strong>Q. What is the minimum age for children?<\/strong><br \/>\nFive for snorkelling, with some shops running family programmes from age one. Ten for discover scuba and fun diving, because of the weight of the equipment and the need to equalise.<\/p>\n\n<p><strong>Q. Which Okinawa dive sites suit beginners?<\/strong><br \/>\nThe Blue Cave at Cape Maeda, Sunabe in Chatan, Naminoue Umisora Park in Naha, Minna Island and Kouri Island. All have gentle conditions, the lowest difficulty rating, and are reachable by car from Naha.<\/p>\n\n<p><strong>Q. Do dives run in the rain?<\/strong><br \/>\nUsually yes. Rain has very little effect on underwater visibility; swell and wind are what cancel a trip. All marine activity stops when a typhoon approaches.<\/p>\n\n<p><strong>Q. Is winter diving in Okinawa worth it?<\/strong><br \/>\nYes. The water holds 21\u201322\u00b0C from December to March and a thicker wetsuit is enough. Plankton levels fall, so visibility is the best of the year, and it coincides with humpback whale season.<\/p>\n\n<hr \/>\n\n<h2 id='wrap-up-pick-the-water-first-then-work-out-what-time-you-leave'  id=\"boomdevs_27\" class=\"main-head\" >Wrap-up \u2014 <span class=\"__text_accent2\">pick the water first, then work out what time you leave<\/span><\/h2>\n\n<p>Diving in Okinawa comes down to two questions: <strong>do you hold a certification card, and how far are you willing to travel?<\/strong> Without a card, the Blue Cave, Sunabe and Naminoue are all open to you. With one, Kerama, Kume and Miyakojima come into range.<\/p>\n\n<p>What connects the two is transport. The sites are scattered along the mainland coast and across island ports, and you will be moving wet gear between them \u2014 which is why almost every itinerary in this guide assumes a car.<\/p>\n\n<p>GO!GO!TOUR compares the national chains and Okinawa&#8217;s local operators on one screen, with an English interface and live chat support. Pickup and return at Naha Airport is standard, and some partners handle out-of-hours collection \u2014 useful when a boat dive meets at 07:30.<\/p>\n\n<p><strong>Five reasons travellers book with GO!GO!TOUR<\/strong><\/p>\n\n<ul>\n  <li><strong>Live chat with a real person<\/strong> \u2014 English support 09:00\u201318:00 Japan time, so questions get answered before you fly.<\/li>\n  <li><strong>A fleet that actually fits<\/strong> \u2014 multiple vetted local operators, from kei cars to 8-seat minivans.<\/li>\n  <li><strong>Flexible pickup and return<\/strong> \u2014 partners that handle out-of-hours collection, which matters for early boat departures and late arrivals.<\/li>\n  <li><strong>Delivery and collection<\/strong> \u2014 paid hotel pickup and return available on selected plans.<\/li>\n  <li><strong>One platform for the whole trip<\/strong> \u2014 marine activities, accommodation and eSIM can be booked alongside the car.<\/li>\n<\/ul>\n\n<div style=\"border: 1px;
