In my mind I thought the Japanese island was a big island that needed a large boat to get there. When we went to tourist office in cabo frio the guy there just told us to go to the canal and ask about a boat to island. No specific directions so we asked someone along the way who pointed us to canal. From there we met another man working on his boat who told us to go down to a traffic cone on shore and shout across water. He then looked across the water and waved and then a guy in a small boat came across his name is sergio. it cost 5 reais each to cross. When across we had a 10min walk to a water crossing at a bar to get onto the small island known as japonese island. We walked around the white sands on the island and paddled in the water which was warm and clean. As the island is small we didnt stay long so we made our way across the rocky crossing and after a walkabout there we left and made way back to sergio and his boat and payed another 5 reais to cross back over. It was something different so not time wasted.

It was very cool the experience, if you want to cross on foot search the sea board and arrive around 9h, 9h30 to catch the low tide give time to enjoy and return on foot. If you want to cross boat they were charging R$25 per person going and going. Good part of the island just where it crosses even pq the back part was with a strong smell of rot and full of urubu in front you can neither see nor feel anything. The lagoon of Araruama was a delight, transparent waters saw many fish and siri, if you have water shoe is a good Pq has a lot of shell and stone on the ground. We found 2 places far to park we got a little lost, but finally we put in the little barbecue that appears in the Maps near the crossing and we managed to park very close. Restaurant with high prices. As we were only going to stay in the morning when we arrived near lunch time we left. It was worth the experience!
