Shinjuku Gyoen is Tokyo's most carefully tended imperial garden — the perimeter and central loops are all continuous smooth surface. Every garden style (English lawn, French formal, Japanese traditional) connects step-free. Accessible toilets at all three gates. Wheelchair-loanable at Shinjuku Gate reception. Fully wheelchair, mobility-scooter and stroller friendly.

• ToiletsAccessible toilets at all three gates, the Rest House, and the Taiwan Pavilion

Because it is Tokyo's decision to hold 58 hectares of near-silence in the centre of Shinjuku — one loop here rewrites what the nervous system thought a city could contain.
