Television series which originated in Japan in the decade 2000s. i.e. in the years 2000 to 2009. Television shows that originated in other countries and only later aired in Japan should be removed from this category and its sub-categories

Pages in this category should be moved to subcategories where applicable. This category may require frequent maintenance to avoid becoming too large. It should directly contain very few, if any, pages and should mainly contain subcategories.
