​A Comprehensive Guide to Yamaha U3 and its Variants
Welcome to our comprehensive guide to the various models based on the renowned Yamaha U3 upright piano. In this article, we'll delve into the details of these exceptional instruments, all of which hail from Japan and are designed to meet the high standards set by Japanese consumers. These models are primarily intended for the domestic Japanese market, emphasizing the meticulous craftsmanship and diversity of options.
Why So Many Different Models?
Japanese consumers are known for their discerning taste when it comes to pianos, which has led to the development of various lines and models. These instruments are not mass-produced for the export market, making them somewhat rare finds outside of Japan.
The letter after U3?
Yamaha's labeling system for their U3 series of upright pianos can be quite puzzling, even for those of us who specialize in piano sales.
​
Well, to keep it simple, the letter that follows 'U3' generally signifies subtle variations in manufacturing years, the materials employed, or the specific features integrated into each model. These distinctions often arise from the unique design and purpose of each piano, contributing to the differences in nomenclature and pricing.
Yamaha U3 Manufacture
First and foremost, it's important to note that every Yamaha U-line piano, without exception, originates from the Hamamatsu factory in Japan.
This facility is the birthplace of all top-notch Yamaha pianos, which encompasses not only their renowned grand piano, the CFX, but also their entire range of high-quality instruments.

Common Top U3
The Yamaha U3H and U3G upright pianos stand out for having the lengthiest production history in the Yamaha U3 upright piano lineup. These pianos are cherished for their ability to produce a warm and rich tone, coupled with a touch that falls in the medium range.
What sets these pianos apart is their unwavering commitment to quality; each one undergoes meticulous fine-tuning and adjustments in our workshop before being made available for purchase.
It's not an exaggeration to say that we consider the Yamaha U3H and U3G as some of the most exceptional modern upright pianos ever crafted, a preference shared by many top-tier musicians.
Yamaha U3 "YU" Series
The YU series, known for its exceptional quality and high demand, receives meticulous handcrafted finishing to uphold the most stringent standards in terms of quality and appearance.
Variations in "X" Models
The "X" series, such as the UX models, represents an upgrade of the U3. These pianos are crafted with higher-grade materials and are specially designed for professionals. Some models even incorporate features typically found in grand pianos. Improved materials are used in the action parts and soundboard, enhancing their performance.
String Length of U3 Versus UX
Internally, the bass strings on the UX models are longer than those on the standard U3 models, despite having the same height. Yamaha achieves this by curving the bridge at the bottom of the piano. Furthermore, higher-grade wood and felt are used for hammers and dampers in all UX models.
Famous "X" System
The X-bracing system in the Yamaha piano is like its secret superhero – it's there to make the piano stronger and sound better. This cool X-brace is like the piano's backbone, ensuring that the beautiful music vibrations made by the strings and soundboard are spread out just right. This brings a bunch of wonderful improvements to the piano's sound, making it sound amazing.
Discontinuation of "X" Models
Yamaha has discontinued producing pianos with X-braces due to the associated extra costs. The scarcity of these models can make them more expensive than their U series counterparts.

Yamaha UX3 (1983-1988)
​Produced in Japan between 1983-1988, Japan introduced the UX-3 piano, an upgraded model of the U3. These UX series pianos are designed with top-notch materials, catering to the needs of professional players.
Inside, the bass strings on the UX-3 are actually longer than those on the standard U3, despite both pianos having the same height. Yamaha achieved this by giving the bottom of the piano's bridge a curvy shape. It's worth noting that due to the extra production costs, Yamaha ceased making pianos with the famous 'X' brace. Additionally, the front panel is crafted in three separate sections, creating a vital air-gap that enhances the release of higher tones and adds a lovely presence for the player.
The UX3 adds a special touch that makes it stand out from other upright pianos – it borrows many parts from the top-of-the-line CF2 concert grand piano.
The UX-3 series might cost a bit more than the regular U3 model because its scarcity value can push up its relative price.
