Picnic Trash Disposal (ゴミの持ち帰り - Gomi Mochikaeri)
The crucial eco rule of cherry blossom parties: you must bag and carry all your empty bento boxes, beer cans, and garbage back to your accommodation. Leaving trash piled up in the park is heavily frowned upon.
Protects the natural beauty of the parks. Littering attracts crows and rats, ruining the beautiful sakura view. High-volume littering has historically forced cities to ban picnic blankets and food altogether in famous parks.
Pack 2 or 3 large plastic garbage bags. Sort your cans, PET bottles, and food waste immediately as you dine. Tie the bags tight at the end, and carry them home or drop them at the park's designated trash centers.
