YBS Preschool Care

1years old – 3years old

Safe and heartwarming bilingual environment

1 to 3 years old will experience the new world in our heartwarming environment.

Our nurturing teachers are aware that they are in a unique position to help young children learn to trust others and develop secure attachments with the important people in their lives. Our curriculum for this age group helps build relationships with children by showing how to create meaningful daily routines and experiences that respond to individual children’ s strengths and interests. Also by being in a bilingual environment, children build up their senses and listening skills to become bilingual. This age group thrives on new experiences, and we fulfill this need by providing care, directions, and projects that allow them to explore the world without stress or pressure. We aim to work with each child as an individual and ensure that each day is a fun-filled adventure.

We believe that children grow up best when they are actively involved with materials and their peers. That is why we place so much emphasis on setting up the proper learning environment and building positive, meaningful relationships with children and their families.By encouraging curiosity, compassion, and a love of learning, our dedicated staff inspires imagination. Through richly textured learning experiences and a carefully designed environment, we encourage children to seek out information and look for facts. We encourage learning in Japanese and English, with speaking, singing. Children also experience a rich variety of educational subjects including finger play songs, art, exploring nature, and more . We also value imagination and playing with possibilities. Teachers encourage creative exploration through art, music, and movement.

YBS education for preschool children

We focused on early childhood education. These are structured learning environments for children before they begin kindergarten. To provide best care with Japanese standards, we use 2 best approaches of Montessori program and play-based learning as our educational framework.

Montessori Approach

Our Preschool developmental program is synonymous with the Montessori program, where all aspects of the environment were created specifically for preschool age children to facilitate the education of young, curious minds. The Montessori Curriculum is an innovative learning framework that incorporates specific learning outcomes and knowledge skills that align with children’s developmental needs and interests.

The idea is for children to learn individually and at their own pace by moving freely around the room and choosing from a wide range of hands-on, age-appropriate activities that are designed to teach specific skills. The primary goal is to help children learn concentration, motivation, self-discipline and a love of learning,

We emphasis on personal responsibility. Children are encouraged to take care of their own belongings and personal needs, such as cleaning up after themselves and preparing their own snacks. Schools aim to foster a healthy self-esteem and sense of independence, allowing children to make their own choices and teaching them basic skills.

The classroom is very structured in its design and in how a lesson is taught.

Play Based Approach

The importance of play on a young child's development cannot be understated. Play gives children opportunities to understand the world, interact with others, express and control emotions, develop symbolic capabilities, attempt novel or challenging tasks, solve problems, and practice skills. Play may contribute to the development of posture, movement, and self-sufficiency. There also appears to be a positive relationships between the frequency and complexity of young children's play and IQ, problem-solving, creativity, language and literacy, and social competence.

Active, play-based learning provides an excellent environment for fostering young children’s cognitive development, especially for those thinking skills essential for cognitive depth.

Bilingual programs and activities

  1. Exposed to Japanese: Students will be exposed to Japanese by spending time with Japanese classmates and teachers. During a school day, children will absorb a new language by listening, singing, dancing, playing in Japanese with peers. It’s perhaps the happiest and best way to learn Japanese through experience.
  2. Life skills: Learning life skills is very important for our students. We teach about being independent, responsible, respect your peers, and much more. We feel that if we instill proper etiquette at an early age, our students will have a better social aptitude.
  3. Potty training and manners: We work on potty training, following rules, sharing together, positive friendships, etc.
  4. Arts: Arts is the best way to develop fine motor skill. Also creativity leads children to open their way of thinking, be creative and become more proactive!
  5. Story time: Listening and imaging the world through a book. it enhances their use of language and its vocabulary it contains.
  6. Music and dance: Exposing students to music and dance helps them to develop gross motor skills, recognize words, and allow them to practice self-expression.
  7. Nature and Community: Children gets to explore outside environment and local town when its nice day. Seeing and feeling the change of seasons, finding nature lives is one of the important learning for children.
