Getting there

Begin the hike by driving to 五宝の滝 carpark. Copy and paste the characters into Google Maps and it will take you there. The road to the parking lot is a bit dicey, particularly in central Yaotsu. The roads are very narrow. There is a toilet in the carpark. From the carpark, follow the sign that says 五宝の滝.

Maps

Google Maps innit (there is also a map at the carpark). 

Route/Trail notes

The hike is very easy. Just be warned that there are some steep stairs that can be easy to slip on, hold onto the rails as you ascend. From the carpark, follow signs for the waterfall, look for the kanji 滝. This will take you to the base of the first waterfall. From here, take the stone staircase upwards to a lookout where you get a spectatcular view of a triple waterfall with a red bridge in-between. 

From the lookout, continue upwards over the bridge and ascend the red staircase. This will loop you around the back and take you to the other four waterfalls. Continue following this path until you loop back to the carpark.
