In 1999, Nintendo stopped manufacturing the Japanese version of the "Koga's Ninja Trick" trading card because it depicted a manji, a traditionally Buddhist symbol with no negative connotations. The Jewish civil rights group Anti-Defamation League complained because the symbol is the reverse of a swastika, a Nazi symbol. The cards were intended for sale in Japan only, but the popularity of "Pokémon" led to import into the United States with approval from Nintendo. The Anti-Defamation League understood that the portrayed symbol was not intended to offend and acknowledged the sensitivity that Nintendo showed by removing the product.
