Seesou-ji temple in Asakusa!
Day time visit a lot of people in there.
And u can some enjoy Japanese things shopping and enjoy buy eat some Japanese sweets in Naka-mise markets.
But, Night time visit, not so much people Quite in there and right up temple it's feel like Romantic in there! ☆
Kabukiza Theatre in Ginza with a single act ticket（roughly 10 USD), Tokyo National Museum in Ueno, and truly traditional Shibamata Taisyakuten Shrine are highly recommended!!
