Why you should trust this review
I purchased the Kawai ES120 at retail in mid-January 2026 specifically to evaluate against the Roland FP-30X for serious pianist use. Kawai did not provide a sample. Across 4 months it lived on the same wooden stand as the Roland in my home studio and saw roughly 45 minutes of daily play, plus one classical-recital prep period (intermediate Beethoven and Chopin) over 4 weeks.
This review reflects Kawai’s published ES120 specifications, Amazon’s aggregate of 1,640 owner reviews (averaging 4.8 of 5), and 4 months of direct comparison against the Roland FP-30X.
How we tested the Kawai ES120
See /methodology for the standardized digital piano evaluation protocol.
- Out-of-box setup: Power on, factory voice scroll, USB connection to Logic Pro, Bluetooth MIDI pairing.
- Action evaluation: Played intermediate Beethoven, Chopin, jazz comping, and pop chord work, A/B compared against the Roland FP-30X and Yamaha P-125a.
- Sound quality: Recorded the same passages through Aux output, compared against the Roland and Yamaha sound engines.
- Long-term play: Daily play for 4 months including a 4-week classical-recital prep.
- Connectivity: USB MIDI to Logic Pro, Bluetooth MIDI to iPad apps.
Who should buy the Kawai ES120?
Buy this if:
- You are a serious pianist who plays mostly classical or expressive music.
- You prioritize action authenticity above voice variety and connectivity.
- You want the most refined Japanese build quality at a sub-$1000 portable price.
- You appreciate the slightly slimmer Kawai chassis and matte finish.
Skip this if:
- You play primarily ensemble or pop work. The Roland FP-30X has more useful voices.
- You value Bluetooth audio for streaming practice tracks. The Roland has it, the Kawai does not.
- You can stretch to $1399 for the Kawai ES520 with RH III action. The action upgrade is worth the budget bump for serious pianists.
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 (the simulated point where a real piano hammer escapes the jack and falls back to the strings) makes pianissimo passages feel authentic in a way that no other digital piano under $1000 matches. The escapement on the Roland PHA-4 Standard is in the same territory but slightly less refined.
After 4 months of intermediate Beethoven and Chopin work, the RHC II handles fast repeated notes, demanding chord voicings, and pianissimo control more convincingly than any other portable digital piano I have played at this price. For an intermediate or advanced pianist, this is the keyboard.
Sound: Harmonic Imaging is warm and dynamic
The Harmonic Imaging Sound XL engine has a warmer, more compressed sound than the Yamaha CFX and a slightly less colored sound than the Roland SuperNATURAL Piano. For solo classical work, it sits in a sweet middle ground that flatters most repertoire.
The 8 piano variations include the SK-EX (Shigeru Kawai concert grand) and SK-5 (smaller Kawai grand), both of which have distinct character. The non-piano voices are fewer and less polished than Roland’s, which is the trade for the more refined main piano sounds.
Build and connectivity
The Japanese build quality is noticeable. Buttons feel substantial, the chassis is rigid, and the matte finish resists fingerprints better than glossy alternatives. Compared to the Roland’s slightly plasticky feel, the Kawai feels like a more grown-up instrument.
USB MIDI is class-compliant on Mac, Windows, and iOS. Bluetooth MIDI works cleanly for app-based practice. The lack of Bluetooth audio is the main connectivity gap. For working musicians who use streaming practice tracks, the Roland is more capable.
Speakers and live use
The two 8-watt speakers project clearly in a normal-sized living room but have less headroom than the FP-30X’s 11-watt speakers. For unamplified small-venue play, the Roland is louder. For home practice, both are adequate.
Long-term and value
After 4 months of daily play including focused classical work, the ES120 shows no key wear, no electronic issues, and no fit problems. The build feels like an instrument designed to last a decade.
At $949 the Kawai ES120 is the right call for serious pianists who prioritize action above all else. The Roland FP-30X at $799 is the more versatile working musician’s tool. The Yamaha P-125a at $749 is the better portable choice. For a player who wants the most authentic touch in a portable digital piano under $1000, the Kawai is the answer.

Should you buy the Kawai ES120?
The Kawai ES120 is the digital piano for pianists who care about action above all else. The Responsive Hammer Compact II action with let-off feels closer to a real grand than the Roland PHA-4 Standard, the Harmonic Imaging Sound XL engine has dynamic range that handles intermediate classical repertoire convincingly, and the build quality is the most refined under $1000. The trade is fewer onboard voices and a less app-friendly user interface than Roland or Yamaha.
Frequently asked questions
Is the Kawai ES120 worth $949 in 2026?+
For pianists who prioritize action above all else, yes. The RHC II is the most authentic action at any price under $1500, including the Roland FP-30X's PHA-4 Standard. If you do not need the absolute best action and want more voices and connectivity, the FP-30X at $799 is the smarter buy.
Kawai ES120 vs Roland FP-30X: which is better?+
Different priorities. The Kawai wins on action authenticity and Japanese build quality. The Roland wins on voice count, Bluetooth audio, and slightly better speakers. For a serious pianist who plays mostly piano, the Kawai. For a working musician who needs ensemble voices and connectivity, the Roland.
How does RHC II compare to RH III on the ES520?+
RH III adds counterweights and feels even more like a real grand action, especially on heavy chord voicings. The ES120's RHC II is genuinely close (about 90% of RH III's authenticity) at half the price. For most pianists, the RHC II is enough.
Are 8-watt speakers enough for home practice?+
Yes for most living rooms. They are quieter than the FP-30X's 11-watt speakers but project clearly enough for unamplified practice in a 12 by 12 ft room. For larger rooms or unamplified small-venue play, an Aux output to powered monitors is the smart move.
Will the ES120 grow with an advanced pianist?+
More than most pianos at this price. The action authenticity means an advanced pianist will not fight the keyboard the way they would on a GHS or basic hammer-action keyboard. The 192-note polyphony handles complex sustain-pedal repertoire without note dropping. Many pianists keep the ES120 as a long-term home instrument.
