Here's a few favorite places I have picked if you are visiting Tokyo one day.
Hie Shrine (日枝神社)
How to go:-
Take the Hanzomon Line to Nagatacho Station (Z04) > Alight and walk 5 mins to Akasaka-mitsuke station, exit station and walk to Hie Shrine via Sotobori-dori street
Tokyo Skytree Tower
Tokyo Skytree is at Oshiage Station.
Mount Fuji is pretty obvious in the photo below
I didn't have enough time to explore the whole of Disneyland because the kiddos couldn't last the whole night, they were tired.
How to go:-
Take Hanzomon Line Z14 -> Jimbocho Station (I10) Alight -> Take Shinjuku Line (S06) -> Shinjuku Station (S01) -> Sasazuka Station (Keio-Sagamihara Line, Hashimoto) -> Tama Center Station
*above is just for reference please ask for directions at the stations because the lines there are quite complicated.
Yup I was there in the day so I did not manage to capture the neon lightings. But I did get to eat Taco Bell! (not avail in SG) Is it just me or the Quesadilla just taste so good?
DIVER CITY TOKYO PLAZA
You can do a lot of shopping there as well.
And I love their toilets because every single public toilet/cubicle I went, they have all these functions! It's my first time in Tokyo so I might sound very suaku about this but seriously they installed these in every public cubicles! I wish Singapore will do the same one day.
