What would you tell a student from our department who wants to study at the same host university as you next year?
Tokyo Institute of Technology is a great university in a central location. The International Student Support Division is very well organized and actively supports students before and during their stay. It is still worthwhile to learn a little Japanese before your stay. The semester is divided into three-month "quarters", which is why lectures with 6 ECTS points will be difficult to credit. It is advisable to write a student paper remotely and to combine this with a Japanese SQ, which can be credited well.
How did you like the city?
Tokyo offers many restaurants and cafes that combine incredible service with top quality. Often the price-performance ratio is much better than in Germany. So even as a student you can afford a "Wagyu dinner" or coffee and cake with a view of the skyline. With a little research, you can find a wide selection of affordable top restaurants for every taste and budget. However, be sure to make reservations well in advance, as many places can be booked up weeks in advance.
If you had the opportunity to describe your stay in a few keywords, what would they be?
Change of perspective, big city, culture, adventure, friends.
