Shiratama

Shiratama (しらたま) is a Japanese adult game (eroge) brand operating under the publisher WillPlus. It is one of several labels in the WillPlus group, a long-standing player in Japan's PC visual novel market. The brand's official website, shiratama-game.com, is an age-restricted portal typical of the adult PC game industry, requiring visitors to confirm they are 18 or older before entering. The site's technical notes reference legacy browser support, indicating the brand has been active since at least the mid-2000s era of Japanese eroge distribution. Shiratama's output consists of bishoujo visual novels — narrative-driven games with anime-style artwork, voice acting, and branching storylines — aimed at an adult male audience in Japan. According to Japanese Wikipedia's disambiguation entry for "しらたま," the brand is described as "ウィルプラスのアダルトゲームブランド" (WillPlus's adult game brand), and it notes that the production company Silver Bullet is involved in the making of most of its works. This production partnership is a notable characteristic of the label, distinguishing it within the crowded WillPlus portfolio. The brand should not be confused with several unrelated Japanese uses of the same name, including a Money Forward automatic savings app, the manga "しらたま!" by Azuma Yuki, the illustrator Shiratama, or the Anpanman character Shiratama-san. Within the commercial brand knowledge base, Shiratama refers specifically to the WillPlus adult game label. As a niche eroge brand, Shiratama operates primarily in the Japanese domestic market, distributing PC titles through the official site and affiliated adult game retailers. Detailed public information about its founding year, executive leadership, and sales figures is limited, as is common for labels in this segment. The brand remains active as of the available evidence, with its official homepage online.

Shiratama is a Japanese adult game brand belonging to the WillPlus group. WillPlus is a Tokyo-based publisher that has maintained multiple eroge labels over the years, and Shiratama is one of them. The brand's official website, shiratama-game.com, presents the standard age-verification gate used across the Japanese adult PC game industry, requiring users to confirm they are at least 18 years old. The site's compatibility notes — referencing Internet Explorer 6.0, Firefox 1.5.4, and Opera 8.5, with a recommended resolution of 800×600 — point to a web presence originally built in the mid-2000s, a period when Japanese eroge publishers commonly maintained such legacy-compatible sites. According to the Japanese Wikipedia disambiguation page for "しらたま," the brand is explicitly identified as "ウィルプラスのアダルトゲームブランド" (WillPlus's adult game brand). The same entry states that the production company Silver Bullet is involved in the creation of most of its works ("一部を除く作品の制作にシルバーバレットが関与している"). This indicates a close production relationship in which Silver Bullet handles development or co-development for the Shiratama label, a common arrangement in the eroge industry where a publisher's brand may rely on an external studio. Shiratama's catalog consists of bishoujo visual novels aimed at the adult male market in Japan. These games typically feature anime-style character art, full voice acting, and branching narrative routes, and are sold on PC. Distribution occurs through the brand's official website and specialized adult game retailers in Japan. As with many niche eroge labels, detailed corporate history — exact founding date, founding personnel, and title-by-title release chronology — is not widely documented in general reference sources. The brand remains active, with its official homepage online. It should not be confused with other Japanese entities sharing the name "しらたま," such as the Money Forward savings app, the manga by Azuma Yuki, the illustrator Shiratama, or the Anpanman character. Within this knowledge base, Shiratama denotes the WillPlus adult game label.
