Long-time travelers understand that a good way to get the most out of their journey is to learn some interesting words in the native tongue. "Isshoni odorimasenka?" is the Japanese way to say "Would you like to dance with me?" And "Benjo wa doko desu ka?", which translates as "Where's the toilet?"
Birthday of Emperor Akihito falls on the 23rd of December, so if you're visiting at this time, put aside your sightseeing and join in the fun and festivities with locals.
