Emi Koyama

In a 2014 interview with Source Weekly, Koyama describes herself as being a "runaway teen" and having engaged in sex work as an adult.

In 2013, Koyama also spoke out against the Forging Justice conference, sponsored by the National Organization for Men against Sexism (NOMAS) and the Michigan domestic violence organization HAVEN. Conference presenters allegedly refused to live stream her panel on intersectional feminism, and had threatened to interrupt it entirely. Koyama's writings on sex trafficking were also reportedly criticized by NOMAS co-founder Robert Brannon; she described Brannon as "violating her boundaries" during later interactions at the conference. Koyama, along with other female presenters at the conference, created a list of demands to NOMAS advocating for reform of the organization’s internal policies to prevent the silencing and mistreatment of female activists.

In 2001, Koyama served as a student intern and program assistant for the Intersex Society of North America, before leaving to found her own advocacy group, Intersex Initiative Portland (ipdx). The organization features classes, workshops, and speakers to discuss social, cultural, and medical issues faced by intersex people. Koyama and fellow intersex activist Betsy Driver also helped found Intersex Awareness Day in 2003, commemorating the first official demonstration by intersex activists in North America.

In 2001, Koyama helped form the Third Wave Feminisms Interest Group at the National Women’s Studies Association (NWSA); the group aimed to "push forward the discussion about third wave feminisms by moving the focus away from generational politics or identity group and onto epistemological and ontological shifts made possible through adopting the label, 'third wave.'" While Koyama has been a regular participant and speaker in NWSA conferences, she has also been notably critical of the organization. In 2008, she published a blog post titled "This is Not a Tribute to Audre Lorde", criticizing the conference's treatment of her and other women of color.

Koyama is an advocate for third-wave feminism and transfeminism, with her 2000 publication "The Transfeminist Manifesto" being one of the earliest usages of the term. As defined by her, transfeminism is "a movement by and for trans women who view their liberation to be intrinsically linked to the liberation of all women and beyond." Alongside fellow Survivor Project member Diana Courvant, Koyama founded the website Transfeminism.org. The now defunct website was created originally to promote the Transfeminism Anthology Project, which aimed to create the first anthology centered around intersex and trans feminist perspectives; the website also served as a general resource surrounding discussion of transfeminism in academia and activism.

Since 2000, Koyama has spoken out against the infamous "womyn-born womyn" policy at the Michigan Womyn’s Music Festival. Her article "Whose Feminism is It Anyways? The Unspoken Racism of the Trans Inclusion Debate" criticized the festival's organizers for a policy that "essentializes, polarizes, and dichotomizes genders." Koyama also participated in a 2002 roundtable published in Bitch magazine focused on the festival, writing "women-only spaces are not as safe or free… but are rife with the same old racism, classism, ableism, and even internalized sexism acted on by women against other women." Koyama advocated instead for an ambiguous "women-only" policy that does not institute or enforce a specific definition of women. Koyama's blog Eminism features an archive that summarizes the debate and compiles historical documents related to the festival.
