HI,

When I was in Tokyo for 2 nights in January ( after 4 days in Hiroshima and before flying home). I went to the Sunshine 60 observation deck at Ikebukuro . There were lots of parents with young infants on the fake grass/shaped like rolling hills along part of the observatory.
I managed to see Mt Fuji rising above a thin layer of smog as well as the Tokyo Skytree.

Some details and nice photos here

Getting to “TENBOU Park” with kids! | Enjoy the observatory | SUNSHINE 60 OBSERVATORY TENBOU-PARK (sunshinecity.jp)

The cafe was reasonably priced ( had a coffee and cake)
And a couple of personal photos

Place to sit. lots of parents and infants were sitting on the grassy floor



View of Shinjuku ( NTT docomo tower ) to the left and Mt Fuji rising above the smog layer to the right with some clouds on top ( in reality the top of MT fuji was clearer than in the photo as it was above the brown smog)


Christmas tree still up on 18th Jan



Gallery of photos enroute to the elevator lobby to take me back down to the exit ( loved the Red moon ( lunar eclipse) and the sun behind Tokyo Skytree and Mt Fuji)
