Meet the HappyRaft Crew…
We have a great team who love living and working on the Yoshino River. All of our guides are licenced by the RAJ - Rafting Association of Japan, and our canyoning guides hold licences from the CIC. We undergo rigourous training throughout the summer to ensure the safest most fun day possible. Our Kitchen staff make the finest river lunches anywhere.
