After coming to take the idea of veganism and zero waste into life, and noticing that the choices are not accessible to everyone, she is hoping to make steps toward a livable environment for all.

Community Development

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).

Norah Hoang

App Development

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!

Business Development

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).
