日本消費税率會超過10%

Recently the Yomiuri News reported the following:
五十嵐文彦財務副大臣は１１日、ＣＳ放送の日経ＣＮＢＣの番組で、消費税率について自身の試算を紹介し、中長期的には「１７％くらい必要になるのではないか」と述べた。
　政府・与党は２０１０年代半ばまでに１０％に引き上げる案をまとめたが、五十嵐氏は「経済成長も同時に考え、色々な手段を取らないといけない」として一段の引き上げが必要だとの認識を示した。
　政府・与党は、１０％への引き上げで社会保障費の増大に備える構えだが、五十嵐氏は、国と地方の基礎的財政収支（プライマリーバランス）の黒字化には１０％では不可能だと強調した。

In a program about Japanese economy on CNBC of CS broadcasting, Fumihiko Igarashi the financial deputy minister introduced his own trial calculation about the consumption tax rate, and said on the 11th that on a mid- and long-term basis, "Isn't it that about 17% would be needed?"
Although the government and the ruling parties had gotten into consensus to pull up to 10% by the middle of the 2010, Mr. Igarashi showed his recognition on the needs to further raise it "as one of the various necessary means to be taken, having considered the economic growth simultaneously."
Although the government and the ruling parties showed an intention to prepare for the increase of social security fee by raising it to 10%, Mr. Igarashi emphasized that 10% was impossible to achieve surplus in balancing the basic finance in the country and the rural areas.

Obviously the consumption tax rate in Japan would be increased gradually beyond 10%.
