A PlayStation Portable (PSP) version of the game was released in Japan on February 15, 2007 by Prototype. The first release of the PSP version came with a special DVD featuring a message from five of the voice actors and a recompiled opening video from the video game version. The five voice actors on the DVD included: Mariko Kōda as Nayuki Minase, Akemi Satō as Shiori Misaka, Mayumi Iizuka as Makoto Sawatari, Yūko Minaguchi as Akiko Minase, and Tomokazu Sugita as Yuichi Aizawa. Yui Horie as Ayu Tsukimiya voiced the short introduction of the DVD, but was not featured in the contents of the DVD itself. A downloadable version of the PSP release via the PlayStation Store was released by Prototype on November 9, 2009. A version playable on FOMA and SoftBank 3G mobile phones was released by Prototype through VisualArt's Motto in May 2007. A version playable on Android devices was released on November 30, 2011. Visual Arts released "Kanon" playable on a Blu-ray player through their Asoberu BD Game brand on December 16, 2011. A version playable on iOS devices was released on April 4, 2013. In the original release, there was no voice acting for the characters, but in the later versions produced for the Dreamcast and PS2, full voice acting was included. The only exception was Yuichi, who was not voiced in either version. However, the PSP release features voice acting for Yuichi, provided by Tomokazu Sugita.
