The most popular beach in Oarai is the Oarai Sun Beach. Because of the shallowness of this beach, Oarai Sun Beach can be quite crowded with visitors. During the summer season, the beach is flocked by swimmers of all ages. Because of its popularity, the beach often holds beach volleyball games as well as surfing races. Visitors can also enjoy a cruise by availing the high-speed pleasure boat from Oarai Harbor.

Aside from being the most popular, Oarai Sun Beach is also the largest beach located in the area of Kanto. Its enormity also contributes to its popularity. Covering a huge area of the coastline, Oarai Sun Beach stretches from the bluffs situated at the edge of the town to the Oarai fishing port in the south. Even though it is popular as a shallow beach, its actual depth is actually near the size of its width.

Typically, a small parking area lies near the access road during the off-season. However, when the summer season begins in mid-July, this parking lot is used for business to take advantage of the traffic that it gets during that season. This is because visitors would really have to cross this area in order for them to reach the actual beach area. With a wide stretch of sand, the beach is filled with beach blankets and umbrellas during the summer season.

Though the shoreline, as well as most sandy parts of the area, are near flat level, they are covered in white sand, which adds to the beauty of the beach. The sand is composed of very fine particles, which lets visitors enjoy its feel on their skin. This also adds to the fact that they would not have to worry about any sharp stones that may hurt their skin.

The beach also features active waves, though these are not as vigorous as those seen in its sister beach known as Oarai Beach, which is located to its north. Because there are not rock outcroppings in Oarai Sun Beach, visitors are also able to enjoy a smooth water surface that is perfect for swimming as well as other water sports.

Changing stations or bathrooms in Oarai Sun Beach are aplenty. Showers are also available for guests to remove seawater and sand from their bodies after swimming or sunbathing. Vendors with their huge stalls can be found at the edge of the beach village for anyone needing any supplies such as toiletries, foods, and drinks. A permanent “beach restaurant” can also be found in the area.

If visitors plan on visiting the beach on a weekend, it is highly recommended to go early. This is because as the time gets late, the amount of people increases. One should also bring lots of liquids before heading off to the beach because vendors typically sell their liquids at a steep price. Having to hike back to one’s car just to get water may also prove to be tedious and tiring.

One of the things that make Oarai Sun Beach extra special is that it is designed to be completely barrier-free, which means that the beach is also accessible to handicapped people or people in a wheelchair. In fact, free rentals of wheelchairs are also available, which can even be used to go into the ocean. In Oarai Sun Beach, everyone can enjoy the ocean.
