How to Buy Vintage Synthesizers & Drum Machines from Japan
Japan built the synths that shaped modern music — Roland, Korg, Yamaha — and the used market is deep. Here’s how to import vintage gear without getting burned on voltage or condition.
Hobby guide · Last updated June 2026 · ~10 min read
Quick answer: Japan is the home of classic Roland, Korg and Yamaha synths and drum machines, with strong, well-kept used supply — sold on Japanese channels, so use a proxy. The two make-or-break factors are voltage (Japanese gear expects ~100V — plan a step-down transformer) and condition (vintage electronics may need servicing). They’re also heavy, so shipping matters.
Many legendary instruments were made in Japan, and the domestic used market is large and generally well-maintained, often at competitive prices. For specific vintage models, Japan is frequently the best place to find a clean example.
The voltage problem (100V)

Japanese gear is built for ~100V mains. In higher-voltage countries you’ll usually need a step-down transformer (sized to the unit’s wattage), unless the unit has a universal or switchable supply. Confirm the voltage and power requirement before buying — running 100V gear on higher voltage can damage it.
What to check before buying
Function — all keys, sliders, knobs, outputs and the display working.
Noisy pots/jacks — common on vintage gear; ask.
Servicing — has it been serviced or recapped?
Completeness — power supply, manual, and any original accessories.
Shipping heavy gear
Synths are heavy and delicate, so shipping is significant and must be well-packed (and insured for valuable units). Total cost = item price + (domestic shipping) + proxy fee + international shipping + possible customs (which can be notable on instruments).
