Support for children's charities in Japan

We are proud of a CSR record stretching back over a decade

Honyaku Plus has consistently sought ways to benefit the wider community, with a focus on helping to raise money in aid of charities that work with Japanese orphans and other vulnerable children in care.

Mirai no Mori

The Tokyo-based NPO Mirai no Mori <> is an excellent volunteer organization which provides life-changing outdoor programs, such as summer and winter camps, for abused, neglected and orphaned children resident in Japanese care homes, so as to support their growth into happy and successful young adults. All of Mirai no Mori’s programs are designed to provide these at-risk children with the skills and knowledge that they will need to forge their own path in life, once they leave the care home.
(Roughly translated from Japanese, Mirai no Mori means something like “green shoots for tomorrow”.) 


The Tokyo-based NPO YouMeWe <> is a volunteer organization that organizes programs for teaching IT skills to care-home children.
These children include both orphans and children who have been the victims of neglect or abuse. Once they leave institutional care at the age of 18, they face a highly uncertain future, and are at risk of drifting into prostitution or crime.
YouMeWe teaches IT skills to these children, and this both enhances their future educational and employment prospects, and affords them some release from their everyday stresses. It also serves to give them more self-confidence and a sense of independence. While its main focus is on teaching IT, YouMeWe also teaches the children language and writing skills, and encourages them to contribute to the local community by helping the elderly get to grips with modern digital technology. Thus, YouMeWe seeks to help the children grow into productive and financially independent young adults who can contribute to their local community.

The Knights in White Lycra

The Knights in White Lycra <> is a team of cyclists who raise money for children’s charities in Japan through various sporting and social activities—the principle one being an annual sponsored 4-day cycle ride around Japan every summer.
