Iioka is a surf spot located about 80 kilometers from Tokyo, attracting a lot of surfers looking for a fun day on the waves. The main beach features a range of jetties and breakwalls that run along the shore, creating some sandbars and channels that help shape the waves. This spot is especially popular on weekends when surfers, often beginners from local surf schools, head out to catch some waves.

The surf at Iioka tends to work best with a southeast swell, but it can also handle swells from the southwest. Waves generally break over sand and can be enjoyable at sizes around 1 foot (0.3 meters) or so. You can expect both left and right-breaking waves, making it versatile for different surfers. The most favorable winds come from the north, and the spot holds up well during low, mid, or high tide, making it accessible for surfers of all levels, especially beginners who are just getting their feet wet.

Iioka is known for its busy atmosphere, especially on weekends, so if you're looking for a laid-back session, try to hit it during the week. The combination of the surf conditions and the crowd can make for an interesting day, so be prepared for some hustle and bustle if you go out when the surf schools are active.
