Staying in a traditional Japanese inn (otherwise known as ryokan) is something that everyone should at least experience once. I have fond memories of a particular ryokan that I stayed in with my family when I was a lot younger and therefore, I decided to stay at KAI Nikko which is operated by one of the most well-known luxury ryokan brands in Japan, Hoshino Resorts. On this very same trip, I also checked out the luxurious modern ryokan which is right smack in Tokyo's Otemachi financial district - the HOSHINOYA Tokyo.
