Pirika Inc. (Chiyoda-ku, Tokyo, CEO: Fujio Kojima, hereinafter "Pirika"), which aims to overcome all environmental problems with the power of science and technology, will hold an online litter-picking event, "15th Anniversary Piri-Cup 2026," to commemorate the 15th anniversary of the launch of the litter-picking SNS "Pirika."
It will run for 5 days from April 29 (Wed/Holiday) to May 3 (Sun/Holiday), 2026. You can participate from anywhere in the world, at any time.
## What is "Piri-Cup"?
"Piri-Cup" is an online litter-picking tournament held annually on the litter-picking SNS "Pirika," centered around "Garbage Day" on May 3. Based on aggregate results such as the amount of litter picked up, we have also prepared gifts like original goods for top performers.
An offline event is also scheduled to be held in Tokyo on April 29 (Wed/Holiday).
Why not start enjoying litter picking during the holiday season when an increase in dropped litter is a concern?
## This Year's Mission: Let's Build a "Virtue Tower" Together!
The theme for Piri-Cup 2026 is "Accumulating Virtue."
- "Accumulating virtue" means gradually repeating good deeds that benefit someone else or society. -
Actually, picking up litter might be one of those "accumulating virtue" actions that cleans up the city and makes someone feel good. In this year's Piri-Cup, we will visualize each of these "virtues" posted on the SNS Pirika together with everyone.
On the special website, the "Virtue Tower" grows by 1 cm for every piece of litter picked up! On the final day of the event, a "Virtue Tower" reflecting the achievements of all participants will appear.
Would you like to join us in visualizing each individual's small actions and tackling a challenge together with users from all over the world?
## Sharing the "Small Happiness" Beyond Litter Picking
This event also focuses on the positive experiences found through litter picking.
- It feels good when the city gets clean
- Someone said "Thank you" to me
- I noticed the beauty of nature
Such "experiences beyond litter picking" are also shared as posting themes, creating new value that goes beyond mere cleaning activities.
