羽田孜
Members of the DPJ were allowed by party leaders to vote based on their own conscience; the party leadership itself was split. Hatoyama overcame his opposition and voted for the bill, along with DPJ Secretary General and Tsutomu Hata. Kan voted against the bill. With the exception of the DPJ, each party voted strictly along party lines, and none among them broke party discipline. Ironically, Hatoyama wanted to use his vote for the bill as a call to his fellow DPJ members for unity. Half of the DPJ supported the bill, reducing the numbers that would have opposed it and making it easier for the bill to pass. The split of the DPJ vote showed the lack of unity of its members.
