Some electrolytic capacitors, especially older ones have markings of "CE" on them. This is short for "Condensateur Électrolytique", the French acronym for Electrolytic Capacitor.
My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.
