Call Japan from Democratic People's Republic of Korea

Japan boasts a highly advanced telecommunications infrastructure, featuring some of the world's most comprehensive mobile networks. Major mobile network operators include NTT Docomo, SoftBank, and KDDI, which provide extensive coverage across the country, including urban and rural areas. As of 2023, Japan has made significant strides in 5G technology, with coverage rapidly expanding in metropolitan areas such as Tokyo, Osaka, and Nagoya. Approximately 98% of the population has access to 4G networks, making mobile internet usage widespread and integral to daily life.

Landline services are also prevalent, although mobile phones are more commonly used for personal and business communications. In fact, mobile phone penetration in Japan is remarkably high, with around 90% of the population owning a smartphone. This level of connectivity facilitates various applications for messaging, video calls, and social media, making Japan one of the most digitally connected nations in the world.

Communication in Japan is rooted in politeness and respect. When answering the phone, people often greet the caller with "moshi moshi," particularly for personal calls. Business calls may begin with the caller stating their name and company, followed by a polite greeting. The use of formal language is crucial, especially in professional settings.

Cold calling is not customary in Japan, and establishing a relationship before making business inquiries is advisable. In personal contexts, text messaging or email may be preferred for initial contact to avoid interrupting someone’s day. Business communications typically adhere to a structured protocol, with an emphasis on clarity and respect. It is common to express gratitude at the end of a call, as this reflects good manners and appreciation for the conversation.

Japan operates on Japan Standard Time (JST), which is UTC+9. Understanding the local time is essential for effective communication. Typical business hours are from 9:00 AM to 6:00 PM, Monday through Friday. It is best to avoid calling during lunch hours, typically between 12:00 PM and 1:00 PM, as well as after 6:00 PM when most people have finished work.

Personal calls are generally better received in the early evening, between 7:00 PM and 9:00 PM, when people are usually home. Be mindful of national holidays, such as Golden Week (late April to early May) and New Year’s celebrations, when many businesses close and people spend time with family. Weekends can also be unpredictable, as people may engage in leisure activities. Planning calls during weekdays, particularly mid-morning or early afternoon, increases the likelihood of successful communication.

When engaging in business calls to Japan, understanding communication norms is crucial. Meetings are often scheduled well in advance, and punctuality is highly valued. Language can be a barrier, so if you are not fluent in Japanese, consider having a translator or using email for initial contact. Written communication is often preferred for formal inquiries, as it allows for clearer understanding.

Professional etiquette is paramount. Begin with your name and company, followed by a polite introduction. Use formal language and titles when addressing the recipient, such as “san” after their name, which denotes respect. Additionally, avoid making direct demands; instead, frame requests politely. Listening attentively and allowing pauses during conversation, as silence is seen as a sign of consideration, can enhance the effectiveness of your business communication.

Japanese mobile numbers follow a clear pattern: they start with 070, 080, or 090 domestically, which means from abroad you dial +81 then drop the leading zero — so a 090 number becomes +81-90-xxxx-xxxx. Landlines carry area codes that reflect geography with unusual precision; Tokyo's is 3, Osaka's 6, Kyoto's 75, and smaller cities get three or four digit codes. The local number length adjusts so the total always comes out to ten digits in domestic format. One type to approach carefully: numbers beginning with 0570 are Navi Dial lines — shared-cost service numbers used by airlines, banks, and utilities — that typically do not accept international calls. Companies will often list a direct geographic number specifically for callers from overseas, and it's worth hunting for that on their contact page rather than dialing the 0570.

Japan runs on JST, UTC+9, with no daylight saving. That fixed offset makes scheduling across time zones predictable: if it's 9 PM in Tokyo it's 8 AM in London, noon in New York. Business calls land best mid-morning, after the first hour of the workday has passed. One genuine call-cost factor in Japan is that landlines and mobiles are priced differently by most VoIP providers, with geographic numbers often cheaper — so a contact's office line rather than their mobile saves money on longer calls. Japan's major national holidays cluster in specific periods: Golden Week (late April through early May) and the Obon period in mid-August bring extended closures. A call to a business during Golden Week will almost certainly reach voicemail, so the surrounding weeks are better. Personal calls to Japanese contacts are almost always better pre-arranged by message; an unannounced call can feel abrupt in a culture that values prepared communication.

In the Democratic People's Republic of Korea (DPRK), the international calling community is relatively small but significant, primarily consisting of expatriates, foreign diplomats, and the families of North Koreans who have defected to other countries. The most common countries called include South Korea, China, and the United States, reflecting the demographics of the expatriate population and the diaspora. According to estimates from various human rights organizations, there are around 30,000 North Korean defectors in South Korea alone, many of whom maintain connections with relatives and friends back in North Korea.

International calling is crucial for residents of the DPRK, as it serves as a vital lifeline to the outside world, offering both emotional support and crucial information. For expatriates, these calls can facilitate business communications and maintain cultural ties. Families separated by borders often rely on these calls to stay connected, share news, and provide emotional reassurance. The restrictive nature of the DPRK's telecommunications environment means that traditional calling methods can be costly and heavily monitored, making the ability to reach out to relatives abroad even more important for personal and emotional reasons.

International calling rates from the DPRK can be prohibitively expensive when using traditional carriers, costing upwards of $3.00 per minute depending on the destination. This high cost often limits the frequency and duration of calls that residents can afford. VoIP (Voice over Internet Protocol) solutions present a more economical alternative, allowing users to make calls over the internet at a fraction of the price.

Despite the DPRK's limited internet access and infrastructure, there are areas in Pyongyang and select regions where internet services are available, albeit restricted. The government has been working on improving the telecommunications sector, and mobile data is accessible to a limited extent, particularly for citizens who own the state-controlled Koryolink mobile service. This availability allows some residents to utilize browser-based calling services, which can significantly reduce costs and enhance the ability to maintain international connections.

For families separated by the borders of the DPRK, the emotional significance of international calls cannot be overstated. These conversations help bridge the gap created by political and geographical divides, providing comfort and connection to loved ones. Technology plays a critical role in maintaining these relationships, allowing families to share milestones and offer support despite the distance.

To ensure regular communication across time zones, it is advisable to establish a consistent calling schedule that considers the time differences. Using online tools to keep track of time zones can be helpful, as can setting reminders for both parties. Regularly scheduled calls can help maintain emotional bonds and alleviate the sense of isolation experienced by families separated by political circumstances.
