Legal status as political party (seitō) is tied to having five members in the Diet or at least two percent nationally of either proportional or local vote in the last Representatives or one of the last two Councillors elections. Political parties receive public party funding (¥ 250 per citizen, about ¥ 32 bill. in total per fiscal year, distributed according to recent national elections results – last HR general and last two HC regular elections – and Diet strength on January 1), are allowed to concurrently nominate candidates for the House of Representatives in an electoral district and on a proportional list, may take political donations from legal persons, i.e. corporations, and other benefits such as air time on public broadcaster NHK.[2]
