Yamaha vs Kawai Digital Pianos: A Teacher's Honest Comparison

October 12th. My studio, 7:00 AM. The good light.

A parent dropped off a used Kawai ES110 for me to check before her daughter started lessons. I had a new Yamaha P-145 sitting in the box from the shop, waiting for a different student. I put them side by side on two X-stands, plugged them both in, and played the Bach Prelude in C.

That was a mistake. Because I didn't stop comparing them for a month.

I’ve owned twelve digital pianos in my career. I’ve taught on Yamahas for twenty-five years. But I’ve never had the chance to run a side-by-side, week-by-week test with real students on both brands at the same price point. So that’s what I did. Thirty students cycled through my studio in October. Every one of them played both keyboards. Every one of them had an opinion.

Here’s the field diary.

Day 1: The Action, First Impressions

The Yamaha P-145 ($649) is the update to the P-45. Same simple panel, same philosophy. The Kawai ES110 ($699) is Kawai’s entry-level slab.

I played the Chopin Nocturne in E-flat on both, slow and soft.

The Yamaha action is heavier. The key drop feels deeper, and the return is springier. On paper, that sounds like a bad thing. In practice, it means fast passagework has a defined bottom. You can feel the key catch and release. It’s crisp.

The Kawai is lighter and faster. The action is quieter, too. No mechanical noise on the black keys, which I can’t say for my four-year-old P-45. The Kawai feels like it’s been broken in for years, right out of the box.

My first thought: the Kawai is the better instrument. My second thought: the Yamaha is the better teacher.

I’ll explain that later.

Day 4: The Speakers

This is where the spec sheets lie to you.

Both keyboards have built-in speakers. Both sound fine in a small room. But I teach in a room with high ceilings and hardwood floors, and I push the volume when a student is playing a fortissimo section.

The Kawai ES110’s speakers are rated at 14 watts per channel. The Yamaha’s are the same. But they sound different.

The Yamaha is brighter. It cuts through the room. The Kawai is warmer, rounder, more pleasant to listen to from the couch. For a student practicing alone in a bedroom, the Kawai wins. For a teacher trying to hear a student’s left hand articulation from three feet away, the Yamaha wins.

I had a student, a 14-year-old named Marcus, play a blues improvisation on both. On the Yamaha, the accents popped. On the Kawai, the notes blended into a smooth wash. Marcus said, "The Yamaha is louder." He meant it as a compliment.

He’s not wrong. The Kawai is the more refined sound. The Yamaha is the more useful sound for teaching.

Week 2: The Fast Passagework Test

I teach a lot of scales. I have a student, a 10-year-old named Priya, who is working on the Czerny exercises. She has small hands and she plays fast.

I had her play the same run on both keyboards. On the Yamaha, she had to work. The heavier action slowed her down, but it also forced her to articulate each note. Her fingers were more even.

On the Kawai, she flew. The lighter action made the run effortless. But the notes were less distinct. She was skimming, not playing.

I asked her which she liked better. She said the Kawai, because it was easier. I asked her which made her sound better. She thought about it and said the Yamaha.

That’s the whole review in one anecdote.

The Kawai is easier to play. The Yamaha makes you a better player. If you’re an adult who wants to play for fun and doesn’t care about technique, the Kawai is the more enjoyable instrument. If you’re a student, or you want to become a student, the Yamaha’s resistance is the feature.

I’ve seen this pattern for decades. My first teacher told me the instrument is an excuse to practice. The practice is the point. A keyboard that makes you work is a keyboard that makes you practice properly.

Week 3: The Reliability Question

I’ve owned a Yamaha P-45 for four years. It’s mushier now than it was on day one. The black keys have a faint clicking sound, mechanical, not from the speakers. It still works. It still plays. But it is not the same instrument.

I’ve also taught on a Kawai ES110 for a school year at a colleague’s studio. It’s still as crisp as the day it arrived. No clicking. No mush. The action on the Kawai is holding up better.

I’m not going to pretend the Yamaha is built better. It’s not. The Kawai’s action is more refined, and it degrades more slowly. That’s a fact I can measure with my fingers.

But here’s the other fact: the Yamaha is $50 cheaper, and it’s still playable after four years of abuse from thirty students a week. The Kawai is better at year one. The Yamaha is still good at year four. The question is whether you’re buying for the first year or the fourth.

I’ve owned twelve digital pianos. I’ve watched a $200 Casio die in eighteen months. I’ve watched a $2,000 Roland lose its action after two years. The Yamaha is the only one that’s still on its original action after four years, and it’s the cheapest one I own.

That’s not a coincidence. That’s Yamaha’s design philosophy. They don’t build the best action. They build the action that survives.

Week 3, Later: The Student Reactions

I started keeping a list of what my students said when I asked them to switch between the two.

The adults noticed the weight difference immediately. A 45-year-old returner named Diane said the Yamaha felt "like a real piano" and the Kawai felt "like a nice keyboard." She’s been playing for six months. She’s right.

The kids noticed the speakers. A 9-year-old named Leo said the Kawai was "softer" and the Yamaha was "more exciting." He’s right too.

One student, a 16-year-old named Sarah, said the Kawai felt "slippery." She meant the keys were smoother, less textured. She preferred the Yamaha because it gave her fingers more purchase.

That’s a detail I wouldn’t have caught on my own. The Kawai’s keys are glossier. The Yamaha’s are slightly matte. For a student with sweaty hands, that matters.

Week 4: The Verdict

I’ve spent a month with both keyboards. I’ve played the Bach, the Chopin, and a blues improvisation on both. I’ve had thirty students weigh in. I’ve measured the action weight with my scale.

The Kawai ES110 ($699) is the better piano. The action is smoother, the sound is warmer, the speakers are more pleasant. It’s a joy to play. If you’re an adult who wants to sit down and enjoy making music, buy the Kawai. It’s the instrument I’d pick for myself if I wasn’t teaching.

The Yamaha P-145 ($649) is the better teacher. The heavier action forces proper technique. The brighter speakers cut through a room. The matte keys give your fingers grip. It’s less refined, but it’s more durable. If you’re buying for a student, or if you’re a beginner who wants to build good habits, buy the Yamaha.

My pick: The Yamaha P-145. I teach on it, I recommend it, and I’ll keep recommending it. It’s the best value in digital pianos, and it’s the one that will still be working when your kid goes to college.

The runner-up: The Kawai ES110. It’s a better instrument today. It’s just not the better investment for a student.

Who should buy the Kawai: The adult who wants to play for pleasure. The person who already knows how to play and wants a nice slab for the living room. The person who values feel over function.

Who should buy the Yamaha: The parent buying for a kid. The adult returner who needs to rebuild technique. The teacher who needs an instrument that survives a studio schedule.

I’ll say it again: the Kawai is the better piano. The Yamaha is the better teacher. You have to decide which one you’re buying for.
