Indonesia has the world’s largest Muslim population, and the majority of Indonesians in Japan practice Islam. When Japanese companies hire Indonesian talent, one of the earliest practical questions they face is how to build prayer (salat) time into the workplace.

Prayer is one of the Five Pillars of Islam and a core of the faith. Alongside dietary rules (halal) and the fasting month (Ramadan), it is central to the accommodations Indonesian talent seek at work. Treating this not as “special treatment,” but as a practical requirement to build into work rules and shift design, is a reliable first step toward higher retention.

This article explains the basics of prayer times for Indonesian talent, workplace response flows, common on-site questions, failure patterns and how to avoid them, and a practical checklist for hiring managers—ready for HR and leadership to use right away.

What Islamic prayer (salat) is: the starting point for understanding Indonesian talent

About 87% of Indonesia’s population is Muslim, and most Indonesian talent working in Japan are Muslim as well. Islamic prayer is called salat in Arabic and shalat in Indonesian. It is an obligatory religious practice performed five times a day in set time windows.

Prayer is not mere custom; it is a religious obligation (fard) stated in the Quran. For devout Muslims, skipping or postponing it is generally not an option. An individual may sometimes decide to skip a prayer when busy, but if a company bans or obstructs prayer for work reasons, that can raise issues of religious accommodation. Understanding this premise greatly improves the quality of workplace dialogue.

Before prayer, a purification ritual called wudu is required. It involves washing the face, hands, arms, and feet with water and can be done at a standard washbasin. The prayer itself usually takes about 5–10 minutes, but including wudu and travel to the prayer place, a practical estimate is 15–20 minutes per prayer.

Prayer is performed facing the direction of Mecca (the qibla). From Japan, the qibla is roughly northwest to west-northwest. There is no need to go to a mosque; with a clean space and a prayer mat (janamaz), prayer can be done in a company meeting room or other room. Friday midday prayer (Jumu’ah), however, has a special status, as discussed later.

Quick reference: the five daily salat and their workplace impact

To manage Indonesian prayer times at work, it is essential to map each prayer window against working hours. The following are approximate windows in Japan (Honshu, typical daylight conditions). Because prayer times follow the sun’s position, they shift by about 30 minutes to an hour with the seasons.

Fajr (dawn prayer) Approximate window: 3:30 a.m.–4:45 a.m.; earlier in summer and later in winter. It usually falls before the start of work, so it rarely affects the workplace directly, except on early-morning or overnight shifts when it may overlap with working hours.

Dhuhr (midday prayer) Approximate window: 11:45 a.m.–1:15 p.m. It often overlaps with the lunch break and is the easiest of the five prayers to accommodate. Workplaces with short lunch breaks or rotating shifts may still need adjustments.

Asr (afternoon prayer) Approximate window: 2:45 p.m.–4:45 p.m. It falls within a standard day shift, so of the five prayers it most often requires workplace coordination. More companies are building it into work rules as a short 15–20 minute break.

Maghrib (sunset prayer) Approximate window: 6:00 p.m.–7:30 p.m., but in winter it can move forward into the 4:00 p.m. hour. It may overlap evening shifts or overtime, and in winter the risk of falling within working hours rises.

Isha’a (night prayer) Approximate window: 7:45 p.m.–9:00 p.m. It does not affect standard day-shift workers, but night and late-night shifts need access to a prayer space.

Of the five prayers, under a typical Japanese day shift (9:00 a.m.–6:00 p.m.) the ones that mainly need practical accommodation are Dhuhr and Asr. Designing an extended (or split) lunch break plus a short afternoon break is the basic realistic workplace response.

Common on-site questions about prayer times

Hiring managers and frontline leaders repeatedly raise questions such as the following.

“If we allow prayer, won’t fairness issues arise with other staff?”

A key point is that granting breaks for religious reasons is acceptable as reasonable accommodation that does not discriminate on the basis of religion or belief. The Ministry of Health, Labour and Welfare guidelines on employing foreign workers also note that consideration for foreign workers’ cultural and religious backgrounds is an expected employer stance. An effective approach is to define prayer breaks in the work rules as a “short-break system for religious reasons” available to anyone who applies. That resolves fairness concerns at the policy level.

“Do prayer times change every day?”

Yes. Prayer times track sunrise and sunset, so they vary by season. Apps widely used in Indonesian communities, such as Muslim Pro, show the day’s prayer times in real time via GPS. When hiring managers know these apps exist, coordination with staff becomes smoother.

“Where should we provide a prayer space?”

You do not need a dedicated new prayer room. A clean, quiet corner of a meeting room, changing room, or part of a storage area can work. Staff almost always bring their own prayer mats. Simply posting a sticker that shows the direction of Mecca in the space greatly increases staff peace of mind.

“Is Friday prayer (Jumu’ah) special?”

Friday midday prayer (Jumu’ah) is in principle a congregational prayer at a mosque and holds high religious importance. From start to finish it takes about 1–1.5 hours, and with round-trip travel to the nearest mosque it can take around two hours. Not every company can allow a two-hour outing every week, but many reported cases reach agreement through flexible arrangements once or twice a month, or by combining one hour of paid leave with the lunch break.

Failure patterns and how to avoid them: common prayer-related trouble

Organizing failure patterns and avoidance measures in concrete terms helps accepting organizations prepare more accurately.

Pattern 1: Prayer is first raised only after hiring

If religious accommodation is not discussed at the interview or post-offer stage, after joining someone may say, “Actually, I need time for prayer…,” leaving both sides unsettled. The remedy is to state clearly early in hiring (at the interview or offer notice): “Please feel free to raise any religious needs.” Much post-hire friction comes from insufficient prior dialogue.

Pattern 2: A prayer space was provided but was unsuitable

Prayer must be performed in a clean place. Cases where space was offered in a scrap corner or near toilets have left staff feeling disregarded and led to resignation. The remedy is to confirm the person’s view once when choosing a prayer space. A five-minute conversation supports long-term tenure.

Pattern 3: Insufficient consideration during Ramadan

During Ramadan, people abstain from food and drink from sunrise to sunset. Managers unaware of the period have misread lower stamina or focus as “lack of motivation” and made careless remarks. The remedy is to note Ramadan dates at the start of the year and agree in advance with the person on shift considerations during the period.

Pattern 4: Prayer arrangements are not explained to others, causing backlash

If prayer breaks are introduced without explanation, Japanese and other staff may feel the arrangement is unfair. The remedy is to explain the content and reasons for religious accommodation to the whole workplace and write them into the work rules. A short internal briefing to help colleagues understand diverse backgrounds can change the workplace atmosphere.

Pattern 5: No water source for wudu on site

In manufacturing, construction, agriculture, and other sites where washbasins are far away, access for wudu becomes an issue. Islamic law provides an alternative dry purification (tayammum) when water cannot be used. When both sides know this, water-access problems can often be overcome.

Points hiring managers often miss: Ramadan, Friday prayer, and individual differences

Three points hiring managers often overlook are especially important.

Workplace impact of Ramadan (the fasting month)

Ramadan is the ninth month of the Islamic calendar and shifts about 10–11 days earlier each Gregorian year. During the fast, food and drink are forbidden from sunrise to sunset, so heatstroke risk rises in years that fall in summer. Referring to Ministry of Health, Labour and Welfare heatstroke prevention guidance, individual shift adjustments and reviews of working conditions are recommended. The meal that breaks the fast (iftar) is permitted at Maghrib prayer time, so enabling people to eat in that window matters.

The special nature of Friday prayer (Jumu’ah) and the importance of prior agreement

Many Muslims prioritize the weekly Friday midday prayer as a religious duty. If “how Fridays midday are handled” is not clarified before hiring, it can cause post-hire trouble. Even where full accommodation is difficult, forming a realistic prior agreement with the person—such as “two days of paid leave per month” or “priority assignment to early shifts”—builds trust.

Dialogue that assumes individual differences in faith

Not every Indonesian worker practices prayer strictly. Devotion varies: some omit prayer while in Japan, others observe all five. Do not assume “Indonesian = strictly observant Muslim” across the board. Confirming actual needs through careful dialogue with the individual is the first step to appropriate support.

For confirming status of residence and preparing employment contracts, we recommend referring to guidelines from the Immigration Services Agency of Japan and work-rules-related laws on e-Gov.

Flow: prayer accommodation from pre-hire through retention

The following organizes prayer accommodation for Indonesian talent by stage, from before hiring through workplace retention.

Step 1: Hiring-plan phase (from about three months before start of work)

Discuss internally whether prayer can be accommodated and decide a policy. Select and clean candidate prayer spaces and post qibla direction markers. Consider adding a “short break for religious reasons” clause to the work rules, and build Dhuhr and Asr windows into shift design.

Step 2: Hiring and offer phase

At the interview or offer notice, explicitly create an opportunity to discuss religious accommodation. Speak openly about how many prayers are needed, preferred times, and Friday prayer, and reflect agreed points in the notice of working conditions.

Step 3: Pre-start orientation

Explain the prayer space location and usage rules. Share where water for wudu is available, and cover shift support and meal arrangements during Ramadan. Providing information in advance on nearby mosques and stores that sell halal food is highly effective for retention support.

Step 4: Retention phase (1–3 months after joining)

Check in regularly on whether prayer arrangements are causing any difficulty. Confirm with frontline leaders that friction with other staff has not arisen, and schedule a confirmation meeting every year just before Ramadan.

Step 5: Continuous improvement phase

Review use of the prayer environment regularly and continue activities that promote understanding of diversity across the workplace. Feeding retention and turnover data back into hiring plans steadily improves the accuracy of the acceptance system year by year.

Practical checklist: prayer space, shifts, and Ramadan

As a practical checklist, the following items help confirm readiness of the acceptance system. Reviewing each item regularly helps prevent oversights.

Prayer space setup

  • At least one clean prayer space (meeting room, changing room, etc.) is secured
  • A marker showing the direction of Mecca (northwest to west-northwest) is posted in the prayer space
  • A washbasin usable for wudu is near the prayer space
  • Staff can bring and store a prayer mat (janamaz)
  • Rules for using the prayer space (times, how to request, etc.) are documented

Shift and work-rules response

  • Work rules include a clause on short breaks for religious reasons
  • Dhuhr (around midday) and Asr (about 2:00–5:00 p.m.) prayer times are built into shift design
  • The policy on Friday midday prayer (Jumu’ah) is stated in the notice of working conditions
  • Shifts allow flexibility for seasonal prayer-time shifts (about 30–60 minutes)

Ramadan response

  • There is a process to confirm Ramadan dates (which change each year) at the start of the year
  • Frontline leaders understand fasting during Ramadan (including no drinking water)
  • Hot environments and heavy-labor shifts can be reviewed individually during Ramadan
  • Shifts are designed so iftar (the meal that ends the fast) time can be secured

Communication readiness

  • Opportunities for dialogue about religious accommodations are provided during hiring interviews and when extending job offers
  • Onboarding orientation includes explanations of prayer, halal, and Ramadan accommodations
  • Other workplace staff have already been briefed on diversity and religious accommodations
  • Regular check-ins (at least once a month) are used to identify requests for improvement

Frequently Asked Questions (FAQ)

Q. Should break time for prayer be deducted from wages?

A. It depends on the work rules and the content of labor-management agreements. Many companies treat prayer time within the framework of ordinary break time under Article 34 of the Labor Standards Act, combining it with lunch breaks or afternoon breaks. If it is treated as an additional unpaid break, it is essential to state this clearly in the work rules and explain it to the employee in advance. The latest text of the Labor Standards Act can be checked on e-Gov.

Q. Is it legally problematic to decline to hire someone because of prayer?

A. Refusing to hire someone on religious grounds is understood as conduct that should be avoided from the standpoint of equal employment opportunity. Guidelines on the employment of foreign nationals from the Ministry of Health, Labour and Welfare also call for not using religious background as an improper basis for hiring decisions. Whether prayer accommodations are feasible should be judged case by case based on whether there is a reasonable impediment to performing the work.

Q. Is it also necessary to accommodate halal food at the same time?

A. Prayer and halal food are separate issues, but from the perspective of supporting retention of Indonesian talent, it is recommended that they be considered in parallel. Even when full halal options in the company cafeteria are difficult, practical accommodations within what is feasible—such as allowing employees to bring their own meals and providing information on nearby halal restaurants—are effective in improving retention rates.

Q. Where can I turn for advice when I am unsure how to respond?

A. When it is difficult for the accepting organization to handle matters alone, consulting a staffing agency, a Registered Support Organization, or a local Hello Work office is effective. Some Hello Work locations have specialized consultation desks for the employment of foreign nationals. In some cases, staff at local mosques also provide companies with information on prayer accommodations.

Q. Is the same response needed for Muslim staff who are not Indonesian talent?

A. Yes. Similar accommodations are expected for Muslims regardless of country of origin. A prayer accommodation framework developed for Indonesian talent can likewise be used when accepting talent from Bangladesh, Pakistan, Malaysia, and the Middle East. Once established, it has the versatility to support talent of multiple nationalities.

Accommodating prayer times for Indonesian talent is not a “special burden,” but rather the development of a workplace environment that meets global standards. As data from the Immigration Services Agency of Japan show, the number of Indonesians in Japan has grown rapidly in recent years, and hiring demand in manufacturing, agriculture, nursing care, and IT is expected to keep expanding. Companies that proactively build prayer accommodations into their work rules and workplace culture tend to earn a stronger reputation among Indonesian talent, and improvements in retention rates have in fact been reported.

Placing understanding of religion and everyday culture at the foundation of your hiring strategy becomes a differentiating factor for securing talent over the medium to long term.
