Tam and her friend Ayaka have come to the observation deck of the Tokyo Metropolitan Government Building. They're meeting up with Mi Ya, who lives in "Haru-san House."
To introduce family members and friends to others, say "[your relationship with the person] no [name (san)] desu." The particle "no" connects one noun to another, with the first noun modifying the next. "San" is an honorific title that's added to a name, but it's not used for yourself or family members.
The Tokyo Metropolitan Government Building, where the skit took place, is in Shinjuku. Its observatory is open to the public. You can enjoy a panoramic view of Tokyo 202 meters above ground. If the weather is good, you can even see Mount Fuji.
Tokyo Tower is famous for its bright orange and white coloring. Tokyo Skytree near Asakusa was built in 2012, becoming the world's tallest tower. Both are beautiful when they're lit up at night.
