@zeng can you offer any suggestions?

Your university helped you, right?

You can add me as a contact. But I it is also good to keep posting here since we can share knowledge with everyone, including those who might want to be exchange students in the future 👍

Unfortunately cherry blossoms are in the spring so that won’t be a possibility likely. However, I have a vague recollection that at Shinjuku Gyoen they have a variety of cherry blossoms from various areas so there is something blooming somewhere year round.

As for the other tours, will you need a car or use public transportation?
