South Korea and Japan face identical 10% Section 122 duties with no Section 301 exposure. South Korea dominates DRAM, NAND flash, HBM, and OLED displays (Samsung, SK Hynix). Japan dominates premium passive components, crystal oscillators, and automotive/industrial ICs (Murata, TDK, Renesas, Rohm). Most complex electronics BOMs include components from both countries.
Both South Korea and Japan face the same 10% effective duty rate. On a $100,000 BOM, both incur $10,000 in duty. The sourcing choice here is about product availability, lead times, and supplier relationships.

Japan and South Korea had a significant bilateral trade dispute in 2019 involving export controls on semiconductor materials (fluorinated polyimide, photoresist, HF gas). This has largely been resolved as of 2023. Both countries' exports to the US are unaffected by bilateral Japan-Korea tensions, and both face the same 10% US Section 122 tariff.
