For the Bapak reading this: Your Menantu is not your employee. She is the mother of your future grandchildren. Treat her with the warmth of Indonesia, not the rigidity of a bygone era.

Indonesian culture traditionally loves guyub (harmonious togetherness). But the "Japan Bapak" brings Enryo (reserve/restraint). Family dinners happen in silence. The Menantu is criticized for "talking too much" or "being too loud." This psychological pressure leads to hikikomori -lite conditions in Indonesian suburbs, where the Menantu locks herself in her room to avoid the father-in-law. The Collision with Modern Indonesia Here is where the social issue becomes critical. Modern Indonesia—especially Gen Z and Millennials in cities like Surabaya, Bandung, and Medan—is rejecting this model.

In the Japanese-inspired model, the Bapak controls 100% of the finances. The Menantu often finds herself asking for permission to buy basic groceries. This creates a modern social crisis: financial domestic violence . The Menantu may have a university degree, but if she is not allowed to work or manage money, she becomes infantilized.

The "Japan Bapak" treats the Menantu not as a new family member, but as a replacement for his wife’s labor. If the Menantu works a corporate job (a modern reality), she is still expected to cook, clean, and manage the household archives—mirroring the Japanese ryosai kenbo (good wife, wise mother) ideal, but without the support system.

Young Indonesian couples are now demanding rumah tangga mandiri (independent households). They refuse to live in the Bapak’s house. They cite the "Japan Bapak vs. Menantu" dynamic as the primary reason for divorce or estrangement.

Indonesia’s recent laws on the eradication of domestic violence (UU PKDRT) now recognize psychological violence. When a "Japan Bapak" gives the Menantu the silent treatment for three weeks because dinner was salty, that is now legally actionable. Is There a Middle Way? Not all hierarchy is bad. The "Japan Bapak" brings stability and work ethic. The traditional Menantu brings bakti (devotion) which is beautiful.
