Welcome to Sewayaki Mariko!

Sewayaki Mariko 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. 

Sewayaki Mariko is a venture inspired by Japanese culture and Japanese educational discipline and manners. 

The business idea of Sewayaki Mariko is endorsed by The London School of Economics and Political Science (LSE) as part of Tier 1 Graduate Entrepreneur Visa scheme.

Mariko recently graduated with a Master’s in Social Anthropology from the LSE and she was selected by the LSE Generate for a Tier 1 Graduate Entrepreneur visa so that she can establish and operate her business in the UK.

“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 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

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 offers.

All of our current services are one-on-one or small group so we can maximize our time focusing on one child or a small group of children. We offer the following services:

  • One-on-one or Small Group Educational & Academic Nanny Services
  • One-on-one or Small Group 7 Plus Exam (Maths, English, Non-Verbal & Interviews) Preparation
  • One-on-one or Small Group English as an Additional Language or/and Bilingual Support
  • One-on-one or Small Group Educational Visits (Museums, Zoo, etc.)
  • One-on-one or Small Group Japanese-style Manners & Disciplines & Life Skills to Become Independent and Global-Minded Citizen

To maximize the educational experience of the child, we focus solely on the child only during our services, which means that Educational Nannies are not allowed to use mobile phones unless it is necessary to communicate with parents.

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