Budapest-Beijing flight 3 days after Japan fligat

Dear Sir, or Madam,

I'm hungarian citizen. I have an flight from Budapest to Beijing with 2 stops and tree days after from Beijing to Fukuoka in Japan with seat reservation.
I start from Budapest-Paris to Wuhan. In Wuhan I have more than 2 hours and I fly from Wuhan to Beijing with China Shoutern.
I won't leave the terminals in Wuhan. In Beijing I'd like to stay 3 days and fly away to Fukuoka.
I need a Visa?
Thank you very much
