Indonesian Communication Characteristics Explained: A Practical HR Guide Covering Culture, Religion, and Workplace Considerations

Strong hierarchical awareness

Languages such as Javanese have detailed honorific systems, and expressions that show respect to superiors are built into everyday communication. In Indonesian as well, polite forms using “Bapak” (honorific for men) and “Ibu” (honorific for women) are well established, and communication premised on hierarchical relationships is common.

If you unilaterally demand that people “speak up more actively” without understanding this background, you risk making them withdraw further.

Indonesian Communication Characteristics Common in the Workplace: Seven Patterns

Below are behavioral patterns actually observed often at companies that have accepted Indonesian talent.

Pattern 1: “Yes” does not necessarily mean understanding or agreement

This is the most frequently reported pattern. There are cases where someone answers “yes” with a smile to an instruction, yet the work does not proceed as instructed. This is not a false reply; it comes from consideration—not wanting to disrupt the atmosphere or trouble a supervisor.

Pattern 2: Indirect expressions that avoid direct refusal

They avoid saying “I can’t” or “I don’t understand” directly and use softer phrases such as “It might be a little difficult” or “I will check.” Even among Indonesian talent who have acquired Japanese, this indirectness can remain as a cultural habit.

Pattern 3: Keeping a smile without showing emotion

Even when feeling confusion, dissatisfaction, or anxiety, they keep a smile and do not show it on their face. It is a sign of politeness, but managers risk misreading it as “no problem.”

Pattern 4: The “Basa Basi” culture that values relationships

There is a habit of inserting a short social greeting or small talk before starting work. Briefly touching on personal topics such as health or recent news deepens trust and makes subsequent instructions easier to accept. One-sided work orders that skip this process can backfire.

Pattern 5: A tendency to hold back when speaking in group settings

Even when asked for opinions in meetings or morning assemblies, many people find it hard to speak in front of a group. One-on-one or small-group check-ins tend to draw out more honest views.

Pattern 6: Differences in time sense (Jam Karet)

Indonesia has the concept of “Jam Karet” (rubber time), a cultural background of somewhat flexible attitudes toward time. Many people feel this gap right after arriving in Japan, so carefully sharing “why keeping time matters” helps them settle in.

Pattern 7: Nonverbal communication that shows courtesy

Nonverbal courtesies appear, such as walking with the head slightly lowered in front of a superior or handing objects with both hands. These are ways of showing respect in Indonesian culture, so sharing mutual understanding helps prevent workplace misinterpretation.

Practical Responses to Religious Observances and Dietary Rules That Affect Indonesian Communication Characteristics

Given that about 87% of Indonesian talent is Muslim, understanding how religious practice affects the workplace is essential for hiring managers. Key practical response points are summarized below.

Responding to prayer (salat)

• The five daily prayers may overlap with working hours
• The two most likely to fall within work hours are Zuhr around midday and Asr around 3 p.m.
• Each prayer usually takes about 5–10 minutes
• Flexible arrangements combined with existing break times are realistic
• In most cases, laying out a mat in an available space is enough even without a dedicated room

Health management during Ramadan (the fasting month)

• Ramadan shifts each year based on the Islamic calendar (for 2026, late February through late March is a rough guide)
• Because food and drink are withheld from sunrise to sunset, physical strain increases in long standing work or outdoor jobs
• Advance notice to on-site supervisors and an atmosphere where people can easily report feeling unwell are important

Responding to halal food

• Food containing pork or pork-derived ingredients, and dishes containing alcohol, do not meet halal standards
• Confirm and arrange before hiring whether the employee cafeteria can be used and what food options will be available at workplace social events

Home-visit needs around Lebaran (Idul Fitri)

• Lebaran is Indonesia’s largest holiday, and spending time with family is strongly valued
• Making paid leave easier to take and showing consideration for return-home wishes directly affect retention

Common On-Site Concerns and How to Avoid Failure Patterns

Common on-site concerns

Hiring managers and on-site supervisors often raise voices like these.

• “Even after a mistake, they do not report it themselves. Why do they stay silent?”
• “I keep repeating work instructions, but nothing improves.”
• “They do not seem to be communicating with Japanese colleagues, but they say there is no problem.”
• “They do not ask for a break for prayer—how should we respond?”
• “They did not discuss resignation in advance, and a resignation notice suddenly appeared.”

What these share is a psychological barrier to putting problems into words and telling a supervisor. A cultural tendency to avoid direct negation or raising issues is in the background, and Japanese sides often realize only later that “we could have responded if they had told us,” repeating the same pattern.

Failure patterns and how to avoid them

Failure pattern 1: Letting them start work after only a verbal check of “Do you understand?”

• Avoidance: Have them try it—“Please show me”—acknowledge what they can do, then move to actual work
• Build not only repeat-back confirmation but also task reproduction confirmation (demonstration) in as a standard step

Failure pattern 2: No report when a problem occurred, so discovery was delayed

• Avoidance: Show day to day that “I’m glad you reported it”
• Building psychological safety that welcomes reporting of mistakes is the fundamental solution

Failure pattern 3: Missing physical changes during Ramadan, leading to a serious mistake

• Avoidance: Share the start date of Ramadan on the workplace calendar
• Set a rule in advance that site leads check in on people’s condition

Failure pattern 4: Serving pork at a welcome party and damaging the relationship

• Avoidance: Confirm halal needs at hiring and share the information with social-event organizers
• Most such trouble can be prevented with one advance word

Points Hiring Managers Often Overlook and Criteria for Judgment

Here are four points that are easy to miss when hiring and accepting Indonesian talent.

Point 1: Assertiveness in interviews does not necessarily match workplace performance

Even Indonesian talent who appear fluent in Japanese and strong in communication at the hiring interview may face cultural brakes on speaking in groups or raising issues on their own at work. It is important to design post-acceptance follow-up on the premise of a gap between interview evaluation and actual workplace behavior.

Point 2: Confirming work allowed by status of residence type

Permitted duties and management obligations differ by status of residence, such as Specified Skilled Worker (i) and (ii) and Employment for Skill Development.Check the latest information on the Immigration Services Agency of Japan Specified Skilled Worker program page and keep the content of the support plan aligned with actual job duties. When hiring as highly skilled foreign professionals, also see ourexplanation of status of residence for highly skilled foreign professionals.

Point 3: Insufficient daily-life support worsens workplace communication

When foundational needs such as housing, a bank account, and a mobile phone are not in place, employees start work while carrying mental anxiety. In that state, proactive communication becomes difficult and isolation is more likely. Refer also to the Ministry of Health, Labour and Welfare page on foreign worker employment measures, and build a support framework alongside confirmation of legal requirements.

Point 4: Cases where dependence on interpreters or support staff deprives the individual of growth opportunities

Leaving interpretation and support entirely to senior employees from the same country reduces opportunities to learn Japanese and communicate directly with Japanese staff. Establishing a phased independence support plan and securing regular opportunities for direct dialogue leads to longer-term retention.

Decision criteria checklist at each hiring and onboarding stage

• Have you cross-checked the type of status of residence, renewal deadline, and permitted work against the latest guidance from the Immigration Services Agency of Japan?
• Have you prepared a daily-life support plan (housing, medical care, and religious considerations)?
• Have you confirmed the status of internal halal arrangements (cafeteria, social gatherings, and food-serving rules)?
• Have you obtained on-site agreement on prayer space and break operations?
• Have you confirmed and completed the obligation to notify Hello Work of the employment status of foreign workers?

Frequently asked questions (FAQ)

Q1: When hiring Indonesian talent, is religious consideration a legal obligation?

Japanese labor law does not contain an explicit provision requiring consideration for a specific religion. However, from the perspectives of reasonable accommodation and of retaining international talent and improving the workplace environment, a certain level of consideration is expected in practice. Refer also to the Ministry of Health, Labour and Welfare guidelines on foreign worker employment measures, and build a framework that avoids labor risks.

Q2: How much does securing prayer time affect shift management?

Each prayer usually takes about 5–10 minutes. The two times most likely to overlap with working hours are midday and afternoon. Designing them together with lunch breaks or official break times can minimize the impact on operations. A dedicated room is not required for prayer space; in most cases, placing a mat in an unused area is sufficient.

Q3: What measures are effective for communicating with Indonesian talent who have limited Japanese proficiency?

The following measures are effective.

• Use plain expressions (easy Japanese)
• Prepare visual work procedure manuals with photos and diagrams
• Incorporate translation tools such as DeepL into work communications
• Combine important work instructions with written and visual information, not only oral delivery

Q4: What can be done about cases where Indonesian talent leave suddenly without raising resignation first?

This relates to a communication trait of avoiding direct refusal, and a pattern is seen in which people reach their limit before putting dissatisfaction into words. Combining regular one-on-one meetings with mechanisms that allow anonymous feedback (such as surveys) makes it easier to detect signs of early departure.

Q5: When hiring Indonesians under a Specified Skilled Worker visa, what points require particular attention in the procedures?

It is necessary to follow the bilateral agreement (MOC) on Specified Skilled Worker with Indonesia and confirm the eligibility requirements for sending organizations and prohibitions on fee collection. The Immigration Services Agency of Japan Specified Skilled Worker system page lets you check country-specific MOC status and application forms. If anything about the procedures is unclear, we recommend consulting a Registered Support Organization or a specialized administrative scrivener.
