Masao Okada began researching phono cartridge design in 1964 and opened the Excel factory in Tokyo in 1970; the company he founded, Excel Sound Corporation, works today from Yokohama. Its first products under its own name were the ES-70 line, initially six models. The business that followed was mostly anonymous. From 1975 through the 1980s Excel built moving-magnet cartridges for Pioneer, Trio (Kenwood), Sansui and Sanyo, and at the peak of the first vinyl boom it was shipping more than 50,000 units a month, which Hi-Fi News later summarized as once the go-to supplier of high-quality moving magnets. Moving-coil designs followed, and the company became the builder of cartridges for Sumiko, with different magnets, yokes and coil formers from anything it would later sell as its own.
Demand for records fell after the compact disc arrived in 1982. Excel kept a small cartridge business for brands that preferred not to name their supplier and diversified into low-priced audio and video accessories, which is how it survived the years when vinyl was declared dead. In 2015 Hiroshi Ishihara of Youtek Corporation reconnected with Okada, and the two developed a line for export under the name Hana, the Japanese word 華, which the company translates as brilliant and gorgeous. The first four models were the EL and EH, with elliptical styli, and the SL and SH, with Shibata diamonds, each in a low-output version for moving-coil inputs and a high-output version for moving-magnet inputs. Herb Reichert reviewed the EL in Stereophile in August 2016, and The Absolute Sound covered all four in March 2017 at $475 and $750. Musical Surroundings of Oakland, California, became the US distributor.
The SL Mono of 2018 added a mono cartridge at $750. In October 2018 the M Series introduced the ideas that define the current range: a nude Microline stylus, a Delrin body with a brass cap, cryogenic treatment of the magnetic circuit, and an 8-ohm generator wound with thicker copper. hi-fi+ named the ML its Phono Cartridge of the Year for 2019. The Umami Red followed, announced on August 3, 2020 and on sale from September 22 at $3,950, with a boron cantilever, a samarium-cobalt magnet, a Duralumin body, an ebony inlay and red Urushi; its name, the fifth taste, was suggested by Garth Leerer of Musical Surroundings. It was hi-fi+'s Cartridge of the Year for 2020 and Stereophile Class A. The Umami Blue of March 2023, at $2,500, put the Red's body and cantilever over the ML's Alnico generator and won a Golden Ear from The Absolute Sound.
In September 2024 the S Series became the SL MK II, SH MK II and SL Mono MK II at $850, with a tapered aluminum cantilever, the 8-ohm generator, cryogenic treatment and the M-Series body; the original SL was cut to $600 and built for about six more months. The Umami Black, announced September 3, 2025 at $11,500, brought a diamond cantilever, a neodymium magnet and the OKD generator named for Okada, and that October an Umami Fest in Healdsburg, California gathered the brand's partners from six countries, with Okada present. The SH MK II won hi-fi+'s 2026 cartridge award, and on September 1, 2026 the E Series MK II, at $550, replaced the original entry models. Okada remains owner and president and designs every Hana; two of his craftsmen have been at Excel Sound for thirty to forty years. Pearl Audio carries the range in Portland.
