"Leaving Wolfsburg is very difficult for me," the 29-year-old Hasebe said. "It's very important for me to play regularly with a view to the World Cup in Brazil (next year). That's why I've decided to take this step."
Nuremberg sporting director Martin Bader said the transfer took so long to go through "due to the high standing he achieved in six years at Wolfsburg."
Hasebe scored five goals in 135 league games after joining the club from Urawa Red Diamonds in January 2008. He helped the team win the Bundesliga in 2009.
Hamburger SV signed German under-21 striker Pierre-Michel Lasogga from Hertha Berlin on a one-year loan deal, with Norway midfielder Per Ciljan Skjelbred going in the opposite direction on another loan.
"Lasogga is the type of striker that we were looking for," said Hamburg sporting director Oliver Kreuzer. "He is an under-21 international, unflinching and he goes where it hurts."
Lasogga missed much of last season through injury.
"I'm on the road to recovery. I've finished my rehabilitation and will try to take part in team training this week," Lasogga told Hamburg's website.
As well as Skjelbred, Hertha also signed 21-year-old midfielder Tolga Cigerci on loan from Wolfsburg.
Bayer Leverkusen secured an option to buy Finnish striker Joel Pohjanpalo from HJK Helsinki with effect from July 1, 2014. The 18-year-old will play on loan at second-division Aalen in the meantime.

Eintracht Frankfurt signed Swiss midfielder Tranquillo Barnetta on loan for one season from Schalke.
"I'm delighted that it has worked out and that I get to know the city and the team," said the 28-year-old Barnetta, who previously played for Leverkusen and Hannover.
Also going on loan is Australian midfielder Nikita Rukavytsya at second-division FSV Frankfurt from Mainz.
Austria striker Marko Arnautovic left Werder Bremen for Premier League side Stoke City in a transfer Bremen managing director Thomas Eichin said "suits all sides."
