I love buildings and I count myself lucky to be living in a great city for architecture and photography. Tokyo also has some great high-rise observation decks.
In the last 12months, the observation decks in the north and south towers of the Tokyo Metropolitan Government Building (Tocho) have been renovated. They are really nice, welcoming spaces now. Sadly, right now, both observation decks are closed because of the Covid-19 virus situation. Hopefully that all changes soon.
