Animazement announced that four Japanese guests cancelled their plans to attend the event. Actresses Noriko Hidaka (Death Note, Inuyasha) and Keiko Han (Mobile Suit Gundam, Sailor Moon), as well as industry members Koichi Tsunoda (Arcadia of My Youth, Mazinger Z) and Yasuo Yamaguchi (Mahou Shoujo Lalabel, Candy Candy) cited a possible 10-day quarantine they may face upon return to Japan, due to concerns over the H1N1 virus.

On May 1, voice actor Tomokazu Seki (Cardcaptor Sakura, Fruits Basket) cancelled his appearance at Animazement for undisclosed reasons. Currently, the rest of the Japanese guests are expected to attend the convention.

Animazement will be held from May 22-24 at the Raleigh Convention Center.
