It sounds like you’re referring to (メッキの根っこ).

Common issues like peeling or blistering often originate not in the plating itself, but in the nekko – due to residual oil, oxides, or improper activation.

If the nekko is weak or corroded, no amount of surface plating will hold. Growth means nurturing the nekko – not just polishing the mekky.

“Mekky” is what everyone sees – shiny, impressive, flawless. But beneath it lies the nekko: your real skills, values, health, and relationships.

In electroplating, the “nekko” (root/base) refers to the substrate material beneath the plated layer. Proper surface preparation of the nekko determines adhesion, corrosion resistance, and longevity.
