Community Outreach Manager

I was born in Hamburg, Germany, and raised in a small town just north of Hamburg. Studying Japanese and Linguistics, I spent a year in Kyoto as an exchange student. The strange misconceptions about non-Japanese people I was made aware of during this time, made me decide to come back to Japan after graduation, thinking that I might use my skills to promote globalization. I’m now based in Osaka, working in translation and international cooperation. For a while now, I have been switching my focus from languages and culture to sciences and environmental awareness (as a second passion of mine).

Originally from Vietnam, Norah came to Japan in 2010 to study Sustainable Development at Ritsumeikan Asia Pacific University. She is now based out of Tokyo. While a recruiter by profession, Norah remains an advocate for sustainable development at heart. She believes in the collective power of each and every individual making sustainable choices every day. Norah was drawing a little map of zero waste shops around Tokyo for her own, when she heard about mamoru. She didn’t need to think twice at the opportunity to join the effort!

Community Outreach Specialist

I am Anna, from Osaka, Japan. After having finished my MA in Peace and Conflict in the UK and Germany in 2018, I came back to Japan to work in a trend agency to learn how the trend has been set and creative industries follow it. During the time I grew my interests in one of the trends, digital and IT, which led me to pursue my career into the field and worked as an IT Specialist for 2 years. In September 2021, I said bye-bye to my beloved Japan, and moved to Amsterdam, the Netherlands.

Sarah left her job in edutech in Singapore after taking night classes in dress making and realised how ridiculous it is that companies can sell clothes at less than $10 when she took a month to make a skirt.

She will be graduating from Fashion School in a few months but is not stressing enough about finding employment (partially because her research project is enough to fill her plate already).
