When we talk about Japan, we would often relate it to fresh sashimi, sushi, and onsen spots. However, with 34,000 km (21,126.6 mi) of coastline, Japan makes an amazing spot for scuba diving as well! While many may have overlooked Japan as a dive destination, you will be surprised with the clear water and diverse marine life as you explore the country’s diving spots. The peak season for scuba diving in Japan starts somewhere around mid-July, as it is nearing the end of the rainy season, and goes all the way to mid-September when the weather starts turning cold! With many beautiful diving spots, it is certainly impossible to get to all destinations in one trip. However, you can always pick one or two spots whenever you visit this intriguing country! Read on to find out about the best spots for scuba diving in Japan.
