Why don’t you experience calligraphy to make memories of Hiroshima? There are only eight brush production centers in Japan, and two of them are located in Hiroshima. Why don’t you experience calligraphy in Hiroshima?
In the calligraphy experience, you can use a brush to write Kanji characters on a clock made of Japanese paper, or onomatopoeia (Boooom!) of your favorite cartoon, and create a T-shirt or sticker. You can also make your own T-shirts and stickers by writing your favorite cartoon onomatopoeia (Boooom!) with a calligraphy brush.
You can make them on the spot, so you can take them home as souvenirs
