This is something elderly people take, but the smell is really unpleasant. I have scary memories of being forced to take it as a kid, and I still can't forget it. I wouldn't recommend it...
I love riding the bus leisurely through the streets of Tokyo, taking in the city's unique vibe in each neighborhood. It's a feeling you just can't get from the subway or trains.
You can enjoy amazing views of Tokyo city and the whole Tokyo Bay. The scenery is breathtaking. The nighttime atmosphere is beautiful—perfect for couples.
