There was Tokyo Game Show, which I went to. Plenty of games, but sadly not a whole lot I was super hyped about. Was lucky enough to pass a 2 hour queue for Psycho Break/The Evil Within, it looked great at TGS, but recently saw that the ending of that game was super disappointing... Went there with a bunch of friends, saw great cosplays and even saw Hideo Kojima in person. Definitely a good trip.
Tried the Burger King Black Burger when that was being sold. Pretty average. Tastes just like a normal Burger King burger to be honest.
Other experiences would be spotting a Japanese wedding at Meiji Shrine, a visit to the Edo era museum, going up Tokyo Sky Tree, a cat café, and a small Lantern Festival. These are things I could recommend taking a look at.
Recently, I was dressing up as Santa Claus for a kindergarten as part of a volunteer event from school. Being Santa Claus for 150-ish kids is an amazing experience. Definitely something to remember!
Also went to Shiodome with my girlfriend to see the Christmas illumination. They know how to decorate and set up a light show here! Until next post, Merry Christmas and Happy New Year!
