Testing Japanese Products in Vietnam: Prepare to Learn About Price, Use and Improvements

Before expanding Japanese product sales in Vietnam, run a focused test with a defined audience and sales method. Look beyond revenue: record who chose the item, for what purpose, and why others decided not to buy. Use those findings in the next purchasing decision and product explanation.

For retailers in Ho Chi Minh City and local sellers of Japanese goods, this article outlines preparation using a limited product range and budget.

Decide what to learn before expanding the range

On October 23, 2026, ACCESS ONLiNE introduced research and development initiatives at Vietnamese consumer goods company Masan Consumer. Small businesses do not need the same facilities or development organization, but they can consider feeding customer responses before and after sales back into product decisions.

Japan's Organization for Small & Medium Enterprises and Regional Innovation (SMRJ) also positions test marketing as a way to gain clues about approaching a market. Instead of assuming an item will sell, treat the test as an opportunity to gather information for the next decision. The following are WIREDREAM VIETNAM's proposals for businesses developing products in Vietnam.

First narrow down whose use situation to test

People buying the same item for everyday home use and as a gift choose it for different reasons. For Japanese tableware, for example, decide whether you are communicating everyday practicality or gift presentation.

Briefly record the product type, target customer, selling location and hypothesis. Rather than asking broadly whether something is popular with Vietnamese people, ask whether this store's visitors would consider it as everyday tableware. Specific questions help determine what to ask and record.

If testing only with existing customers, note that their product knowledge and relationship with the store differ from those of new customers.

Establish the conditions for actual sales first

Check import, labeling and storage readiness with responsible staff and appropriate specialists. Then clarify price, stock, handover and the contact for returns or defects.

Record test prices or incentives separately from normal conditions. The next decision differs depending on whether customers buy only with a discount or also consider the regular offer.

Set the test period, quantity, spending limit and treatment of remaining stock in advance. This prevents the test from continuing indefinitely in response to every new reaction.

Avoid changing too many conditions at once

If price, photographs, wording and location all change, it becomes difficult to understand differences in response. Limit the conditions compared to fit the question you want to answer.

For example, to test whether customers understand a use case, keep the product and price consistent while changing the explanation and recording responses. If the timing or audience cannot be matched, note those differences. Do not infer causation or market-wide trends from one small trial.

Check that Japanese and Vietnamese explanations match in quantity, price and conditions. Do not add unverified performance or benefit claims to make the product more attractive.

Briefly record reasons for not buying too

Alongside sales volume, record questions when customers handle the product and reasons they give for not buying. Begin with fields staff can maintain without excessive workload.

• Intended use: home use or gifting?
• Questions asked: operation, size, price, care or something else?
• Reasons for not buying that the customer actually expressed.
• Difficulties or further questions after purchase.
• Situations where stockouts or insufficient explanations prevented a sale.

Separate staff assumptions from customers' actual words. No questions does not mean no dissatisfaction; leave unknown items as unknown. Design records that explain purchase considerations without requiring personal names or contact details.

Separate social media responses from buying and usage feedback

More saves or inquiries on social media do not necessarily lead to purchases or continued use. Review communication responses, purchases and post-purchase usability separately.

If people do not discover the product, examine photos and presentation. If questions do not lead to purchases, review explanations and conditions. If problems arise after purchase, consider improving the product or instructions. For repeat-purchase items, allow for the time needed to use them up. Do not judge durable tableware solely by short-term repeat orders.

Finish by deciding what to continue, change or stop

For each product, separate findings from what remains unknown. Choose the next action, such as changing the audience, revising explanations or narrowing the range.

Do not make a large additional purchase merely because an item sold once; consider stock risk and support workload. Conversely, if customers did not notice the item on the shelf, low sales may be insufficient to conclude that demand for the product itself is absent.

Frequently asked questions

How many units and how long should a test run?

That depends on price, buying frequency, channels and budget. First define the question, then set a period and quantity that can provide opportunities to answer it.

Can feedback on free samples be enough?

It can reveal first impressions and usage issues, but differs from choosing to pay. Treat opinions and actual purchases separately.

What if a wholesale customer's store helps with the test?

Alongside sales conditions, agree on the explanations and records requested from staff and how findings will be shared. Keep the work within a range that does not disrupt the store's usual operations.

Develop Japanese product sales locally through testing

WIREDREAM VIETNAM supports Japanese product import, wholesale and local sales-channel development. Organize the product, intended customers and potential buyers to clarify what should be tested locally.
