Good option for souvenirs for your home
There may be people who are going back to their home countries during the spring vacation.
If you are one of those people, you might want to think about getting some Japanese style tiny goods for souvenirs for 100 yen!
There is a Japanese style goods section named “和風空間(Wafu-Kukan (=Japanese style space))” in the 100yen shop called the DAISO on the basement floor in DayzTown. They sell many kinds of tiny goods there, such as ukiyoe postcards, paper fans, rice bowls, tea cups, lucky-cat dolls, store curtains, etc. I believe the prices are reasonable and these items should be a nice conversation starter with your family and friends in your home country.
Have a nice stay at home!
