Pearl was founded by Katsumi Yanagisawa -who began manufacturing music stands in Sumida, Tokyo- on April 2, 1946. In 1950, Yanagisawa shifted his focus to the manufacturing of drums and named his company "Pearl Industry, Ltd."
By 1953, the company's name had been changed to "Pearl Musical Instrument Company," and manufacturing had expanded to include drum kits, marching drums, timpani, Latin percussion instruments, cymbals, stands, and accessories.
Yanagisawa's eldest son, Mitsuo, joined Pearl in 1957 and formed a division to export Pearl products worldwide. To meet increasing worldwide demand for drum kits following the advent of rock and roll music, in 1961 Pearl built a 15,000 sq ft (1,400 m2) factory in Chiba, Japan to produce inexpensive drum kits, also known as "STENCIL KITS" that bore the brand names of more than thirty distributors such as Apollo, Coronet, Maxwin, CB-700, Stewart, Werco, Ideal, Crest, Revelle, Revere, Roxy, Lyra, Majestic, Silvertone, Toreador, WESTBURY and Whitehall.
In 1966, Pearl introduced its first professional drum kit, the "President Series".
In the early 1970s, Pearl was distributed in the U.S. by Norlin, the parent company of Gibson guitars at the time.
Today, Pearl's Taiwanese operation encompasses five factories whose output supplies nearly the entire worldwide market for Pearl products. The original Chiba factory now caters to the domestic Japanese market, producing drum kits, marching drums, timpani, and symphonic chimes.
Pearl created several drum products, such as shells in the 1970s that were made of wood with a fiber-glass lining. There was also a shell made of a composite called "Phenolic." Additionally, Pearl combined roto-toms and these Phenolic shells to create the Vari-Pitch line of drums. Other early innovations included shells that were slightly undersized, so that the drum head would extend over the edges, much like a gong drum. Pearl manufactured seamless, extruded acrylic shells that were different from the tabbed-and-seamed Vistalite shells used by Ludwig. Pearl also developed the hinged tube tom-arm, a design widely copied by many other drum manufacturers.
Pearl has made shells for more than 30 companies. In the 1960s, they ceased making shells for other companies, and began manufacturing drums under their own name and used the Pearl logo for the first time.
Their construction technique is known as SST or "Superior Shell Technology." All Pearl drums feature this construction. Each ply is placed into a cylinder, and pressure is applied from both sides. While in the press, the shell is heated to bring the glue to a boil, thus forcing it through the wood grain and fusing the shells very tightly. The individual plies are scarf jointed, and all the seams are offset, resulting in a "seamless" drum (Pearl demonstrates the strength by parking a Humvee with its tire on a tom shell). This creates a drum shell of incredible strength.

The first generation of Export drums were made of 9-ply Philippine mahogany, and the newer were made with 6 plies (7.5mm) of Poplar, with the ECX series being made from maple, and come standard with Pearl's ISS tom mounting system. They were discontinued and replaced by the Vision series (VMX - 6ply maple, VBX - birch, VSX, VX) and later reintroduced in 2013 (as the EXX) to replace the Forum line.

The shells were 7-ply, 7.5mm: One inner ply of birch, one outer ply of birch, and five middle plies of mahogany. Toms had Superhoops. Rack toms had I.S.S. Mounts. Prestige Session and Performance Session still retained the WLX designation and came with traditional double lugs, while SLX had high tension lugs and came with better hardware. In 1994, the SLX became the SPX Prestige Session (lacquered) and SX Session (wrapped) Series. The SX shells were 8 ply Mahogany and Laminate while the SPX shells were 7 ply birch and mahogany. In 1997 SRX Prestige Session Select replaced SPX and SX line. The shells were 7 ply maple and mahogany. In 2001 SRX Prestige Session Select became the SRX Session Custom, 6-ply all-maple shells with the OptiMount suspension system and 2.3mm SuperHoops II. In 2004 SRX became the SMX Session Custom 6 ply 100% maple series, and SBX Session Custom all birch. Sessions were discontinued in 2006 to make way for Vision series and MCX Masters Custom in 2007. These drums were extremely popular, but expensive. The Session line was later reintroduced in 2012 as the Session Studio Classic.

In 2007, Masters series was simplified into two lines: Masters MCX and Masters Premium. The first Masters kits from 1993 had 1.6mm steel hoops, the same as Export. In 1994, they were switched to 2mm steel (gold plated) and 2mm stainless steel. In 1996, they were switched to 2mm steel. In 1997, they were switched to 2.3mm SuperHoop II's. In 1999, they were switched to die cast. Most of their finishes are now available on their Masters Premium and Reference series drums.

World Series (WLX/WX) - The World Series was introduced in 1986. They were placed between the Export and DX/DLX kits, and the only differences were tom arms (Worlds came with the TH-80 Tom Holders, whereas the higher series had TH-90 tom holders), and the DX/DLX had super hoops (V1). In 1987, World series replaced DX/DLX series. Shells were 8 ply shells - 2 inner plies were linden, 5 plies mahogany, and 1 outer ply birch. Later shells (from 1989) were 7-ply birch/mahogany. They came in both wrapped (Performance World WX 6500) and lacquered (Prestige World WLX 6500) models. Eventually in 1990 after running side by side with the SLX (Pretige Session Elite) the World Series was renamed the Prestige (WLX) and Performance (WX) Session Series. These 2 models shared the exact same shells the differences being the snare drum, 1 colour option and the SLX had the high tension lugs. Jazz series, the Prestige Session Jazz retained the WLX designation.
Custom Z - Drums made from maple (CZX) or birch (SZX), 8ply (10mm) snares and rack toms, 10ply (12.5mm) floor toms and kick drums. The CZX was introduced in 1989, and discontinued in 1994.

In 1991, the CZX Studio Series, also known as the SZX, was introduced. The SZX featured 100% birch shells in the same thickness as the CZX. Tom sizes, however, were limited to power sizes and bass drums were only available in 16" depth. The SZX was available in #131 Midnight Quartz, #133 Crimson Quartz #110 Sequoia Red, #113 Sheer Blue, #103 Piano Black, and #109 Arctic White. 1993 was the last year of production for the SZX.

The line was discontinued in the U.S. in favor of the less expensive MCX series, but continues to be sold in Japan and Europe. However, it can still be ordered as a "special order" in the North American market.
Masters Premium Legend (MPL) – Introduced at the 2011 Musikmesse music fair, the Legend Series incorporates most of the features found in the Reference Pure series such as Fat Tone hoops, thinner shells, and lightweight swivel tube lugs (snares only), all of which are designed to reduce the kit's weight. Unlike the Masters Premium line, these drums are only made from maple, with the choice of 5,4 mm. These drums are available only in Europe.
Session Studio Classic (SSC) – Introduced at Winter NAMM 2012, the Session Studio Classic line reintroduces the Session Series for the first time in five years. These drums are made 6 plies of birch and kapur (referred to Pearl as their "Session Formula" shells), and feature Remo drum heads (Pinstripe on the toms, Powerstroke 3 heads on the bass drums), OptiMount tom mounts, and SuperHoop II hoops. These drums are made in Taiwan.
Masters Custom (MCX/BCX) - Drums made from 6 plies of maple and birch. These drums replace the entire Session and Masters Premium lines until the introduction of the Session Studio Classic, with the only difference being that they feature die-cast hoops, Masters Series lugs, Masters Series OptiMount tom mounts, and Remo drum heads. They are the same configuration as the Masters Premium MRP kits, but they only come in 5 finishes with bright chrome being the only hardware option. As a result, the drums are not made up as a "custom" stock. Since they are warehoused in large quantities, time between order and delivery are much shorter. These are made in Taiwan.

Hardware and PedalsEdit
In addition to producing drums, Pearl has also produced hardware for its drum and percussion instruments as well as pedals. One of Pearl's major improvements was the introduction of the Uni-Lock tilter on their tom mounts and cymbal stands. Introduced in 1982, the Uni-Lock tilter uses a frictionless, gearless tilter, allowing the player to make more precise angle adjustments to their toms and cymbals. This was further improved with the introduction of the Gyro-Lock tilters which rotate a full 360 degrees. Most of Pearl's pedals come equipped with PowerShifter heel plates, which allow the player to adjust the pedal's feel by sliding the plate either forwards or backwards.
