From Guesthouse tabi-tabi, take a 40 minute bus ride down and around the coast to Nakagi, pay a 1000 yen for a 5 minute boat ride and you’ll arrive at the underwater wonderland, Hirizo. Before boarding the ship you can pick up some cold drinks, and rent the required snorkel and mask for only 500 yen. Do pack well, Hirizo is nothing but a rocky beach. There are no toilets or vending machines. We brought beach chairs, a parasol, towels, fins (flippers), sunscreen, drinks, snacks, and an underwater camera. If you have a wetsuit or surfing vest it will keep you in the water longer and let you dive deeper as it can get pretty chilly hanging out with cold blooded creatures all day. There are tons of fish to see! I wish I knew the names of them all but can just tell you there are big ones, little ones, blue ones, yellow ones, and striped ones. Some hang out in massive schools while others can be seen hiding alone between rocks and soft coral. We spotted lots of sea anemone too but have yet to find any nudibranches (colorful sea-slugs) but I know they are out there somewhere! Will be back soon with a better pair of goggles to help me find the finer creatures. Click on any pic for my flickr set!
Please be aware that on days when waves are big or the sea is choppy there will be no boats heading to Hirizo. You can find contact details for Nakagi and Hirizo on their (Japanese only) website here.
UPDATE: Word has spread and Hirizo has become famous, and is now infamously crowded. You may want to save your Hirizo adventure for an off-season weekday.
