Dress code

Hello, i am a freshman at TAISI, Waseda University. There is the entrace ceremony on the 21st, Sep, and I don't really know how to dress for it. Some people say I need to wear something business casual and others told me to wear just casual clothes. Is there anyone who can help me. There is also the welcome event for FSS new students. I do not know how to dress for that either? Can you help me? 🙂
