Next up on the journey to Fukuoka included a short layover in Osaka. We arrived in the early morning and our overnight bus wasn't leaving until much later that night, so we decided to do the usual Osaka bits: mess around, shop, eat okonomiyaki & takoyaki, shop more, etc.
The highlight of the layover and possibly the whole trip was the final hours before we left spent unwinding at Spa World Onsen. If it's not apparent from my facial expression, we love onsen and this was the most amazing onsen experience I have ever had. This 8 story building/hotel is complete with an outdoor swimming area, water slides, separate mens/women's floors, an arcade area, and a floor just for eating. Are you in awe yet? Good.
After 5 blissful hours in the onsen we caught our overnight bus and headed over to Fukuoka. Moral of the story: if you're gonna have a time gap somewhere, have it in Osaka.
