The word hāfu (ハーフ, "half") is used in Japanese to refer to somebody who is biracial, i.e., ethnically half Japanese.
 The label emerged in the 1970s in Japan and is now the most commonly used and preferred term of self-definition.
 The word comes from the English word "half" indicating half foreign-ness.
50 Skidillion Watts, also known as "50,000,000,000,000,000,000,000,000,000,000 Watts Records", was the label used by brothers David and Jad Fair of the punk rock band Half Japanese to release their first albums recorded in the late 1970s.
The Kooks are an English pop rock band formed in 2004 in Brighton.
 The band currently consists of Luke Pritchard (vocals/rhythm guitar), Hugh Harris (lead guitar/synth), Alexis Nunez (drums), and Peter Denton (bass guitar).
 The original bassist was Max Rafferty, and the founding drummer was Paul Garred.
 The lineup of the band remained constant until the departure of Rafferty in 2008.
 Dan Logan served as a temporary replacement, until Peter Denton joined the band permanently in October 2008.
 Early in 2010, Pritchard announced the departure of drummer Paul Garred, due to a nerve problem in his arm.
 Late in the year, Garred rejoined for studio sessions, however Chris Prendergast played drums when the band played live.
 Garred finally left in November 2011 after the release of their third album, "Junk of the Heart".
Greatest Hits is the first compilation album released by the punk rock band Half Japanese, in 1995.
 It includes the line ups from all albums released by the band.
Half Japanese is an art punk band formed by brothers Jad and David Fair around 1975, sometime after the family's relocation to Uniontown, Maryland.
 Their original instrumentation included a small drum set, which they took turns playing; vocals; and an out-of-tune, distorted guitar.
 Both Fair brothers sang, although over time Jad moved into the frontman role.
 The band members are John Sluggett - guitar, Gilles-Vincent Rieder - drums, Jason Willett - bass, Mick Hobbs - guitar, and Jad Fair - vocals and guitar.

The Musashigawa stable (武蔵川部屋 Musashigawa-beya?)
 is a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables.
 It is an off-shoot of the better known stable of the same name set up by former "yokozuna" Mienoumi in 1981, that changed its name to Fujishima stable when former "ōzeki" Musōyama took over as head coach in September 2010.
 Former "yokozuna" Musashimaru branched off from this stable in April 2013 after taking on the elder name of his former head coach, starting a new stable using the Musashigawa name, and starting a new generation of Musashigawa stable.
 This is the second stable in sumo history to be headed (and founded) by a foreign-born former sumo wrestler after Takamiyama's Azumazeki stable.
 The head coach's nephew is a wrestler at the stable under the shikona of Musashikuni and is ranked in the makushita division as of 2017.
 The stable is also home to the half Japanese, half African-American wrestler Wakaichiro.
