What you will learn in this article

Beyond the features of Vietnamese, this article also covers Japanese rephrasing that lands at work, how to use translation apps, and confirmation check-ins.

After welcoming Vietnamese employees, companies often face issues such as limited Japanese proficiency or difficulty conveying job-specific terms. You may also find some of their Japanese phrasing unfamiliar. Understanding the features of Vietnamese, however, often makes smoother communication possible. This article explains those features and practical tips for using them in workplace communication.

Vietnamese feature 1: Based on the alphabet

Vietnamese is written with the alphabet plus tone marks and vowel marks above or below letters. The type of mark changes a word’s pronunciation and meaning.

Many distinctive readings and pronunciations

Although Vietnamese uses the alphabet, it does not use the four letters F, J, W, and Z. Pronunciation can resemble English, but tone marks and vowel marks create distinctive sounds. Vietnamese names are often spelled the same way yet pronounced quite differently.

Vocabulary centered on Chinese-character origins

For a long time Vietnam’s official language used Chinese characters, and Chinese influence remains strong, so most words can be written with Chinese characters. In practice, familiar characters are combined and their pronunciation is written in the alphabet. Because Japanese was also influenced by Chinese, some words sound similar—for example, 注意 = Chú ý (chu-i).

Strong English and French influence as well

Many Vietnamese words also reflect English or French influence, so Japanese speakers can often recognize them. When answering the phone, Vietnamese speakers often say Alo. It is said to come from mimicking a French-accented “Hello” during the French colonial period. Caphe (cà phê) for coffee has a similar background.

Vietnamese feature 2: Grammar mixes English and Chinese

Vietnamese grammar is built as an isolating language, forming meaning through sequences of words, as in Chinese. Word order is basically SVO, as in English.

Expressed mainly in SVO order

Vietnamese word order is subject + verb + object, as in “I drink coffee.” As a result, Vietnamese speakers still getting used to Japanese may say something like “I drink, coffee.” When teaching the Japanese needed for work, focusing on simple verbs and nouns supports smooth communication. The key is not to worry too much about differences in word order.

Little inflection

Although Vietnamese resembles English in some ways, its structure is simpler, with almost no inflection. Because it is an isolating language, adding words that mark past, present, or future is enough to express time relationships. Many Vietnamese speakers, however, do not use tense markers, so they tend to express even past or future matters in a present-like form.

Direct phrasing is also a feature

Because Vietnamese draws on Chinese-style isolating structure and English-style SVO, expressions tend to be quite direct. For example, when someone cannot work overtime they may say “I cannot,” and when they are not hungry they may say “I will not eat,” in a blunt-sounding way. It may feel abrupt, but this also comes from the features of Vietnamese. It helps to give such phrasing some leeway.

Vietnamese feature 3: Approachable even for Japanese speakers

Vietnamese differs from Japanese in many ways, but simple conversation can be picked up relatively quickly.

Pick up only the Vietnamese you need

Expressions needed at work are not covered in standard Japanese textbooks. One option is to weave simple Vietnamese into work-related communication. Vietnamese has many sounds unfamiliar to Japanese speakers, though, and longer phrases become harder to convey. The key is to pick up nouns alone or verbs alone. With a single word, Vietnamese colleagues can often guess what you mean even if the pronunciation is imperfect.

Use a translation app together

Smartphone culture is widespread in Vietnam, so most Vietnamese people are comfortable with translation apps. Communicating in Vietnamese through a translation app is therefore another option. Google Translate is familiar to many Vietnamese users and has relatively few mistranslations, so it can support Vietnamese-language communication. Translating short SVO phrases rather than long sentences helps prevent communication mistakes.

Mixing in gestures is also effective

When you bring Vietnamese into conversation, pairing it with gestures makes communication even smoother. When Japanese colleagues use imperfect Vietnamese with hand gestures, Vietnamese colleagues often feel freer to use imperfect Japanese as well—a useful synergistic effect.

Summary

Vietnamese pronunciation can be complex, but because the language resembles English in some respects, it is not beyond Japanese speakers’ understanding. Some Vietnamese words also resemble English or Japanese, so actively using what you recognize can support smoother communication.

Differences between Vietnamese and Japanese workplace communication

Because Vietnamese word order is relatively clear-cut, indirect Japanese requests or vague cautions can be hard to convey. At work, state “by when,” “what,” and “what counts as done” in short sentences, and have the person repeat them back to confirm.

In post-hire training, combining plain Japanese, photos, real objects, and translation apps is more reproducible than aiming for perfect Vietnamese. Practical on-site approaches are organized in Japanese Communication with Vietnamese Colleagues at Work.
