Enjoy a fix of vitamin D at Miho Beach. Once you've topped up your tan, stick around and watch the sky change color as the sun starts to set.
This stretch of coastline won't cost a thing, which will be music to your ears if you're after free things to do. You'll find Miho Beach in Shimizu Ward. There are loads more places to experience nearby, including Tokai University Marine Science Museum, Chibi Maruko-chan Land and Bay Dream Shimizu.
