Welcome to Sewayaki Mariko (世話焼きまりこ)!

Sewayaki Mariko Ltd was established in March, 2019 by Mariko Kobayashi, a Japanese entrepreneur, to answer the demands of the communities of pre-preparatory school families and expat families in London. It is a venture inspired by Japanese culture and Japanese educational discipline and manners.

The business idea of Sewayaki Mariko Ltd is endorsed by The London School of Economics and Political Science (LSE) as part of Tier 1 Graduate Entrepreneur Visa scheme. “Educational Nanny” is the term Mariko has created to answer the demands of both local British families and expat families in London, particularly families who send 2-6 year olds to pre-preparatory school to prepare for the 7 Plus exam or/and expat families who are new to London and need English as an Additional Language or bilingual supports. British and expat families are looking for high quality “Educational Nannies” who are qualified educators to work as both nanny and tutor. While engaging with children’s questions on paper and in real life, “Educational Nannies” answer the demands of this specifically-targeted market, providing native speaker expertise, educated and polite grooming and basic household duties for children. The business idea of Sewayaki Mariko Ltd was born and the venture is currently in the middle of providing a matching service for such families to high-quality university students (“Educational Nannies”) in London. Moreover, it is scheduled to provide a new service inspired by a Japanese way of childcare in which the elderly in the local community share their lifelong knowledge with the next generation of children as “Educational Nannies.” Thus “Educational Nannies” can dip into a mine of experienced university graduates and accomplished seniors to support hard-working parents with younger children who want to learn these important skills quickly. According to market research coordinated with our clients in London, there are currently no such services in the London market that match exactly with what Sewayaki Mariko Ltd offers. For example,

Our business aims to achieve the following social impacts:

  • Interactive and positive learning experiences for children who sit for 7 Plus exam
  • Support for expat families who are new to London
  • Employment opportunities for university students and the elderly to match them with hard-working parents who seek high-quality Educational Nannies

Thank you very much for your interest in Educational Nannies. We look forward to serving your family very soon.

20638625_996202516356_4362244595589957723_n-1 My name is Mariko Kobayashi. I am a multilingual (English, Japanese, Arabic and Spanish) Japanese who is an entrepreneur, founder, director and Educational Nanny of Sewayaki Mariko Ltd. I grew up in Tokyo, Japan. I have been based in London since September, 2017. I am also a part-time Japanese-language consultant at King’s College London’s spin-out OSINT (Open Source Intelligence Collection) consultancy Ridgeway Information to carry out open source research in support of its non-proliferation research projects. Sewayaki Mariko Ltd is inspired by Japanese culture and Japanese education of discipline and manners. From receiving education at an international-oriented high school in Tokyo until the present moment establishing Sewayaki Mariko Ltd in London, I have lived, studied and worked internationally in various cities of the world including Cairo (Egypt), Leiden (The Netherlands), my hometown of Tokyo (Japan) and currently London. Before relocating to London, I held a full-time professional position at a US government organization in Tokyo, Japan, while working on a part-time basis as an English-speaking nanny and educator serving 0-12 years old children of Japanese and expat families in Tokyo. I have been learning about different cultures and languages since I was a child. I have always loved London because I felt very comfortable and welcomed on each visit. The opportunity to move to London came when I was accepted into the Masters Program in Social Anthropology at The London School of Economics and Political Science (LSE). Not only have I practiced my own educational nanny methods with expat families (Japanese, American, European nationals etc.) and local British families, but also I have networked with them in London for the past one and a half years. Throughout this process, I have identified that there is a strong demand for high-quality Educational Nannies among the pre-preparatory school families and expat families in London. Sewayaki Mariko Ltd is the start-up created to serve this niche and the market research pilot study has proven that this venture can support these families’ unique educational interests. From the onset, I came to the UK with a goal of doing a PhD degree in Anthropology at Oxford, but lack of funding opportunities motivated me to pursue my other interest- practicing Japanese educational methods to meet current demands of my clients in London. For example, many of my clients will invest in preparing their children for the 7 Plus exam, practicing their English as an Additional Language or receiving my help to become global-minded citizens. Once I made this discovery and identified their needs, I applied for a business competition at LSE where the top business ideas are selected to be sponsored for the scheme of Tier 1 Graduate Entrepreneur visa application. Subsequently, my business idea of educational nanny services for pre-preparatory school families and expat families in London was selected by LSE Generate and here I am now- able to run the business and serve the communities who have been waiting for my creative educational nanny methods. As I begin my entrepreneurial journey, I am very grateful to the many families I have worked with in London who have been supporting me. I try my best to support these families and their children in an understanding and compassionate way. By enjoying and listening to their unique educational needs and their journeys as a family, I have focused on filling a gap in the household services sector of the United Kingdom. The most rewarding part of this start-up is the experience and moments I spend interacting with children. I am very grateful for the feedback from my clients and their children, and especially pleased to hear that they are happy with my services. While it is natural for me to believe that Sewayaki Mariko Ltd was born thanks to the great support and encouragement from these special families in London, I must also acknowledge the support I was given from local ethnic communities, particularly the Japanese community and other expat communities in London. My business started to spread mostly thanks to word of mouth. On this occasion, with the establishment of Sewayaki Mariko Ltd, I would like to say that I am very grateful that other families who did not know me in the past have read the website about Sewayaki Mariko Ltd. I am delighted to get to know these families and many more families in London who are looking for Sewayaki Mariko Ltd’s unique educational supports. Please contact us if you would like Mariko or our staff’s support for your children’s unique educational needs. Thank you very much.

What is Educational Nanny? How is Educational Nanny different from regular Nanny and Tutor?

“Educational Nanny” is the term Mariko has created to answer the demands of both local British families and expat families in London, particularly families who send 2-6 years old children to pre-preparatory school to prepare for 7 Plus exam or/and expat families who are new to London and need English as an Additional Language or bilingual supports. Mariko has often been consulted by clients who have unique educational needs. These families have been looking for high-quality “Educational Nannies” who are qualified to work both as nannies and tutors to engage children by answering their questions both on paper and in real life. To answer the demands for this specifically-targeted market, the business idea of Sewayaki Mariko Ltd was born and currently provides a matching service for these families with high-quality university students (“Educational Nannies”) in London or/and the elderly in the local community who would be interested in supporting the families with younger children. Since Mariko relocated to London in fall 2017, she has been practicing her own methods of educational nanny services for pre-preparatory school families and expat families in London. She has been well received and encouraged by the communities that have inspired her to focus on catering to their educational needs on a full-time basis. According to market research coordinated with her clients in London, there are no existing services in the market that match exactly with what Sewayaki Mariko Ltd offers.
