HAYAMI's thoughts on establishing a grass straw

The grass straw brand "HAYAMI" was launched by three young people.


By 2050, marine plastic waste will exceed the number of fish. I felt a sense of urgency that if I continued to live like this, I would not be able to swim in the beautiful sea or eat delicious fish in a few decades.


Despite being called a developed country, Japan has low awareness of sustainability and the environment, and mass production and mass consumption are taken for granted, considering only immediate costs.

Therefore, we launched the Grass Straw Project to realize a sustainable Japan.


Without the earth, not only business but also human beings cannot live. In order to build a world where loved ones and loved ones can live comfortably in the future, we who live in the present need to take action. Small changes in each person's daily life will lead to major changes that will change the future of the earth.


Although it is a small change called a grass straw, we would like to contribute to the construction of a sustainable society by making many small changes.
