The number of Korean-Japanese couples is actually on the rise.
This is not a vague claim. According to the 2024 marriage and divorce statistics released by Statistics Korea, the number of marriages between Korean men and Japanese women was 1,176, the highest since 2015. Related reports cite the increased number of avenues for meeting each other through matching applications and online communities as one of the reasons behind this increase.According to data from the Ministry of Foreign Affairs, the number of Koreans residing in Japan will reach approximately 409,000 as of June 2025. If Koreans staying in Japan for study, expatriate work, or working holidays are included, the actual scale is much larger. In other words, this means that the demand from Koreans looking for a serious romantic partner in Japan is by no means small.
Why is it particularly difficult to find a serious romantic partner in Japan?
Although the Japanese dating app market is already very large, most are designed with Japanese UI and focused on domestic Japanese users. Pairs is the overwhelming number one app in Japan, and while it is frequently used by those seeking serious relationships due to its strict identity verification process, it is a service designed primarily for Japanese-speaking users.While there are some specialized apps for Korean-Japanese couples, most focus on casual meetups or language exchange, and there are not many that explicitly advertise "meetings based on a serious relationship."Also, while global apps like Tinder and Bumble have the advantage of being available in English, they are often perceived in Japan as being primarily for casual meetings, so they may not be a good fit for those seeking a serious relationship.In other words, the realistic problem is that from a Korean perspective, there are surprisingly few options available that allow for comfortable communication in English while simultaneously aiming for a serious relationship.
Can I date seriously without a language barrier?
The difficulties most commonly faced by people in international relationships in Japan can be broadly divided into three categories.First, it is difficult to accurately understand the nuances of profiles and messages. Japanese-specific euphemisms often fail to convey their true meaning even when translated by a machine translator.Second, it is difficult to determine whether the other person wants a serious relationship or a casual encounter. In Japanese dating culture, rather than directly asking about the direction of the relationship, people often try to figure it out gradually over time, which can be confusing for foreigners with different cultural backgrounds.Third, on platforms lacking identity verification or safety mechanisms, it takes a long time to trust someone you meet for the first time.For this reason, simply looking for an "app that supports English" is not enough. Along with language support, it is much more important whether the platform is clearly designed with a specific direction for the relationship.
Practical ways to find a serious romantic partner in Japan
Before choosing a platform, it is a good idea to check the following three things first.
- Can I specify relationship goals (serious dating, marriage in mind, etc.) in my profile?
- Is it possible to check compatibility of values or lifestyles before meeting the other person?
- Can you control whether to reveal your face or the level of personal information exposure yourself?
If a platform is equipped with these three features, the likelihood of the relationship going astray is significantly reduced, even if there is a language barrier.
