The Twitter Japan blog releases a list of top hashtags for each week. Tweet Beat investigates the buzz behind the hashtag.

Politics could not beat enthusiasm for #猫の恩返し (in English, "The Cat Returns") airing on Friday night, although Nippon Television and TBS radio's coverage of the Upper House elections under #zero選挙 and #senkyo954 respectively both made it into the top 20 hashtags of last week.

The Liberal Democratic Party of Japan's official #日本を取り戻す ("Take back Japan") was a bit more popular than the demonstration hashtag profiled here a couple weeks ago, #愛国競争 ("patriotism competition"). Meanwhile, boys' love otaku campaigned under their own hashtag #bl選挙 ("boys love election").
