What is Bilingual Education? An Easy-to-Understand Guide to Benefits, Points to Note, and Age-Specific Approaches

Bilingual education is gaining attention as an educational method to help children acquire two languages from early childhood. While many parents want their children to become proficient in both Japanese and English, there are often many unanswered questions, such as “At what age should we start?”, “What should we do at home?”, and “How can we avoid failure?”

This article explains the basic concepts of bilingual education, its benefits, points to note, and age-specific approaches, along with practical tips for implementation.

What is Bilingual Education?

Bilingual education refers to an educational method where students learn while using two languages on a daily basis. However, it is not simply about learning a language. Here, the definition, background, and typical methods of bilingual education are explained in detail.

Definition of “Bilingual”

The word “bilingual” combines “bi” (two) and “lingual” (language), referring to a person who can speak two languages. Generally, people tend to think that a high level of fluency is required. In reality, however, there are no strict criteria; being able to handle daily communication in a second language is often considered being “bilingual.”

Therefore, many people consider someone bilingual if they can engage in daily conversations and simple communication, even if they are not at a native level.

History of Bilingual Education

According to research by Ritsumeikan University, bilingual education spread in the United States during the 19th century along with an increase in immigrants. As people with different languages began living in the same society, bilingual education gained momentum.

Initially, classes were even conducted in the immigrants’ native languages; however, after World War I, the movement toward English unification grew stronger, and multilingual education was temporarily scaled back. Later, the importance of multicultural coexistence was recognized again, leading to the diverse language education seen today.

In this way, bilingual education has a history of experiencing temporary declines before shifting back toward multilingual coexistence.

Typical Methods of Bilingual Education

One of the most attention-gathering and typical methods of bilingual education in the world today is the “immersion method.” This educational approach spread against the backdrop of Canada’s English-French coexistence policy. It is a style where subjects like science and social studies are learned in English or French, rather than studying the language merely as a subject.

Its feature lies in creating an environment where students “learn while using” the language, rather than learning the language itself. Many international schools use this immersion approach as their core framework.

Benefits of Receiving a Bilingual Education

Bilingual education offers benefits that go far beyond simple language acquisition. It is said to have a significant impact on brain development, the improvement of thinking skills, future career building, and the cultivation of a global perspective.

Here are three typical benefits of receiving a bilingual education.

1. Improvement of Cognitive Brain Functions

It is known that bilingual individuals switch between two languages, which stimulates brain activation and strengthens neural circuits. Furthermore, language switching and selection require advanced cognitive processing. As a result, multiple studies have shown that bilinguals have higher memory, concentration, and problem-solving skills compared to monolinguals (speakers of only one language).

2. Deepening Cross-Cultural Understanding and Broadening Perspectives

Learning another language simultaneously means understanding the culture, history, and values of another country. By acquiring English, opportunities to experience the ways of thinking and lifestyles of people in other countries increase, naturally cultivating an understanding of different cultures.

This fosters flexible thinking that accepts diverse values and a broad perspective, equipping children with the ability to thrive in a global society.

As globalization accelerates, English proficiency has become a crucial skill, providing a major advantage in job hunting and promotions. Not only does acquiring English potentially make it advantageous to find employment at global companies, but it also expands the range of professions that utilize English, such as interpreting, translating, and international sales.

Additionally, acquiring the ability to research and disseminate information in English significantly expands business possibilities, which is a crucial point.

Points to Note About Bilingual Education

While bilingual education has many benefits, there is a possibility of negative consequences if the wrong approach is taken. In particular, maintaining a balance with the native language and sustaining the language environment are critical points.

Prioritizing the Development of the Native Language (Japanese)

The most important aspect of bilingual education is the acquisition of the native language, Japanese. Since thinking skills are formed based on the native language, if a child learns English while their understanding of Japanese is insufficient, there is a risk that the development of both languages will stunt.

A major pitfall in bilingual education is that parents often focus so much on English acquisition that the development of the native Japanese language is neglected. Firmly developing vocabulary and expressive skills in the native Japanese language first is the key to improving English proficiency and succeeding in bilingualism.

The Risk of “Semilingualism” Where Both Languages Are Underdeveloped

In bilingual education, there is also a risk of falling into “semilingualism.” Semilingualism is a state where, despite learning two languages, neither is sufficiently mastered.

When a child becomes semilingual, complex thinking and various expressions become difficult, affecting the growth of their thinking and communication skills. Falling into semilingualism poses risks of lowering self-esteem and negatively impacting academic performance.

The “One Person, One Language” Principle and the Risk of Language Mixing

If the same person continues to mix Japanese and English while speaking, there is a risk that the child will not be able to distinguish between the languages, making language confusion more likely.

In bilingual education, the concept of “One Person, One Language” (OPOL) is considered important. This is the basic principle that when speaking to a child, “one adult consistently uses one language.” For example, by strictly ensuring that parents speak in different languages—such as the father speaking English and the mother speaking Japanese—the child will naturally learn to distinguish the languages.

Continuous Effort is Necessary to Maintain Language After Returning Home or Changing Environments

Even an acquired language can be rapidly forgotten if the environment in which it is used changes. This is because, when removed from an English environment, a child’s brain rapidly discards English as “unnecessary information.”

To maintain English proficiency, it is necessary to secure opportunities to be exposed to English daily, even after returning to Japan or changing environments. For example, consistently engaging in “meaningful English” every day through English conversation, reading, or interacting with native speakers is highly effective.

Conversely, even when a Japanese child attends an international school, it is highly recommended from the perspective of native language retention to ensure daily interaction with Japanese at home.

Bilingual Education by Age and Situation

In bilingual education, the appropriate approach differs depending on the child’s age and the environment they are in. Understanding the approach that suits each developmental stage is the key to success.

Ages 0-5 (Early Childhood)

The preschool period of ages 0 to 5 is a time when the capacity to absorb language is extremely high. It is a period when children can naturally acquire a language just by being immersed in an English environment, featuring an ease of language acquisition without undue strain.

Therefore, attending a preschool or international school with resident native teachers is one of the most rational choices.

On the other hand, since language loss also occurs very rapidly during this period, it is necessary to pay attention to retaining Japanese alongside English. Do not forget to firmly develop the foundation of Japanese as well.

Lower Elementary School (Ages 6-8)

Children in this period begin to develop logical thinking. Therefore, it is important to firmly solidify the foundation of their language.

Providing consistency in the language environment—whether Japanese or English—builds the foundation for language acquisition and greatly impacts subsequent thinking and learning abilities. Studying in a consistent environment while anchoring on one language leads to the formation of stable linguistic abilities.

Regardless of Age or Roots, Environment and Continuity Determine Success or Failure

Whether bilingual education can succeed in Japan depends heavily on the “approach method” and “continuity,” regardless of age or home environment. For instance, even in families where parents speak different native languages, it is actually quite common for a child not to become bilingual without active parental involvement.

Also, even for returnee children from overseas assignments, if the language environment cannot be maintained after returning to Japan, their English proficiency will rapidly decline.

It can be said that the success of bilingual education is determined by three elements: “Environment” (what language is spoken and with whom), “Continuity” (how long the effort is sustained), and “Motivation” (whether the child finds it enjoyable).

Points for Succeeding in Bilingual Education in Japan

To succeed in bilingual education in Japan, it is important to prepare the environment from both the home and the school.

Ensure the Child Enjoys Learning English

One of the keys to success is ensuring that the child enjoys learning, rather than forcing English studies upon them. For young children, “learning” is an extension of “play.”

By utilizing English songs, picture books, games, and animations, naturally incorporate English into daily life and nurture the feeling that “English is fun.” This eliminates resistance to learning English, fosters a proactive attitude toward learning, and leads to long-term continuation.

The “Living English Environment” Realized by International Schools

At international schools, daily life itself becomes an English environment, increasing the necessity to use English, which helps students acquire practical language skills. A major feature is that knowledge and language skills can be acquired simultaneously through daily communication with native teachers and all-English classes.

Furthermore, by interacting with children of multiple nationalities, cross-cultural understanding naturally deepens, and a global perspective is cultivated. Such an environment is difficult to achieve solely at home, and gaining the experience of “using” rather than just “learning” English is a significant advantage.

International schools naturally possess an environment where students can immerse themselves in English—an “immersion environment.” An international school that provides a “living English environment” can be considered one of the best options for children to comfortably acquire practical English skills.

Conclusion

Bilingual education has the power to greatly expand not only language skills but also thinking abilities, global perspectives, and future possibilities. On the other hand, a balance with the native language and the continuous creation of a conducive environment are essential, making it vital to proceed with the appropriate methods.

It is difficult to prepare an environment at home where children can focus on English while having fun—a living English environment. To expand future options, enrolling your child in an international school from an early stage might become one of your candidates.
