For hanami 花見, it's common to lay down a tarpaulin to reserve a place for viewing and picnicking, with some people camping in advance to secure the best spots for themselves or businesses.
Even with the crowds the atmosphere of the park was always relaxed. Maybe this is something that can only exist in Japan, and maybe saying as much is cliché, but it's hard to imagine anywhere else.
Nearby, the recently restored Ueno Tōshō-gū 上野東照宮, shining at the end of an army of lanterns.
Slightly to the north where food vendors crowd the arbors along paths and gates, the Kan'ei-ji five storey pagoda 旧寛永寺五重塔, almost four hundred years old, casts your eyes to the sky.
From afar, a time traveller would see the pagoda like a beacon on the landscape, fixed and unchanging as the metropolis exploded.
Quiet excitement in the many paths and ways.
A moment aside the river of people.
Further into the park, on paths paralleled by lanterns, blue tarpaulins and a growing canopy of brilliant white.
Out of the bustling station and absorbed by Ueno Park 上野公園 and the increasing density of those partaking in hanami 花見, the traditional custom of flower viewing. The park is famous for its extensive sakura 桜, in particular the white/pale pink Somei-Yoshino 染井吉野, part of what makes it the most popular city park in Japan. Despite it being a Monday, the crowds were a sight on their own.
