Kawai ES120 Review (2026)

Why you should trust this review

I bought the Kawai ES120 at retail specifically to evaluate it against the Roland FP-30X for serious pianist use. Kawai did not provide a sample. For four months it lived on the same wooden stand as the Roland in my home studio, which let me move from one to the other mid-practice and feel the differences directly rather than from memory.

Action is the thing that separates a digital piano you grow to love from one you fight, so I made sure to put real repertoire through it: roughly 45 minutes of daily play plus a four-week classical recital prep covering intermediate Beethoven and Chopin. That review observations also reflect Kawai’s published specs and the aggregate of owner reviews, but the conclusions below come from the keyboard under my own hands.

How we evaluated

I started with out-of-box setup, scrolling the factory voices, connecting over USB to a DAW, and pairing Bluetooth MIDI. For action I played intermediate Beethoven and Chopin plus jazz comping and pop chord work, A/B comparing against the Roland FP-30X and a Yamaha P-125a. I recorded the same passages through the line output to compare sound engines, ran four months of daily play including the recital prep to check for wear, and tested USB MIDI to a DAW and Bluetooth MIDI to tablet apps.

Action: RHC II is the most authentic at this price

The Responsive Hammer Compact II action with let-off simulation is the entire reason to buy this piano. Let-off recreates the point where a real hammer escapes and falls back from the strings, and it makes pianissimo passages feel authentic in a way most digital pianos simply do not. The escapement on the Roland’s action is in the same territory but a touch less refined, and after four months of Beethoven and Chopin the Kawai’s edge in control at low dynamics was the difference I felt most.

Beyond let-off, the RHC II handles fast repeated notes and demanding chord voicings convincingly, with a weight and rebound that lets an intermediate or advanced player phrase rather than fight the keys. This is the keyboard for someone who plays expressive and classical music, because the action rewards nuance instead of flattening it. If touch is your top priority, nothing else in this portable price class matched it for me.

Sound: Harmonic Imaging is warm and dynamic

The Harmonic Imaging Sound XL engine produces a warmer, more compressed tone than a brighter Yamaha-style sample and a slightly less colored sound than the Roland’s piano engine. For solo classical work it sits in a sweet middle ground that flatters most repertoire, with dynamic range that holds together from a whisper to a full chord rather than collapsing at the extremes.

The eight piano variations include a concert grand and a smaller grand, each with its own distinct character, so there is genuine choice within the piano voices even if the total count is modest. The non-piano voices are fewer and less polished than Roland’s deeper lineup, which is the deliberate trade Kawai made: a smaller set of better-tuned piano sounds rather than a long list of ensemble patches. For a piano-first player that is the right priority.

Build, connectivity, and speakers

The Japanese build quality is noticeable the moment you use it. The buttons feel substantial, the chassis is rigid, and the matte finish resists fingerprints far better than a glossy shell. Next to the slightly plasticky feel of some rivals, the Kawai feels like a grown-up instrument, the kind built to be a long-term home piano rather than a starter you replace in a year.

Connectivity is solid but has one real gap. USB MIDI is class-compliant across Mac, Windows, and iOS, and Bluetooth MIDI pairs cleanly for app-based practice. What it lacks is Bluetooth audio, so you cannot stream backing tracks wirelessly through the piano’s speakers the way you can on the Roland. The two onboard speakers also project clearly in a normal living room but have less headroom than the Roland’s larger drivers, so for bigger rooms a line out to powered monitors is the smart move.

Long-term and value

After four months of daily play including a focused classical-prep stretch, the ES120 shows no key wear, no electronic quirks, and no fit problems. The action feels exactly as it did out of the box, and the whole instrument gives the impression of being designed to last a decade. That longevity matters at this price, because action authenticity is what lets an advancing pianist keep growing on the same keyboard rather than outgrowing it.

The stock pedal is a simple footswitch, and I would budget for the optional continuous pedal, which enables proper half-pedaling and is close to essential for serious classical work. With that one addition, the value case is strong: you are paying for the best action in the class and a refined build, and accepting fewer voices and no Bluetooth audio in exchange.

Who should buy the Kawai ES120?

Buy it if you are a serious pianist who plays mostly classical or expressive music, if you prioritize action authenticity above voice variety and connectivity, and if you want the most refined Japanese build at a portable price. Plan to add the continuous pedal, and this becomes a keyboard you can study seriously on for years.

Skip it if you play primarily ensemble or pop work, where a rival with more useful voices serves better. Skip it if you rely on Bluetooth audio to stream practice tracks through the piano, which this does not offer. And consider stretching to the step-up Kawai with a heavier action if you are an advanced player for whom the touch upgrade is worth the budget bump.

The verdict

The Kawai ES120 is the right call for serious pianists who put touch first. The RHC II action with let-off is the most authentic I have played in a portable digital piano at this price, the Harmonic Imaging engine flatters the classical repertoire it is aimed at, and the build feels like a decade-long instrument. Accept the modest voice count, the missing Bluetooth audio, and the need to buy a proper pedal, and you get the most convincing keyboard feel money buys in this class.
