Below is a song by Moriyama Naotarou, a famous Japanese singer singing "Hana" (flower).
Japan has many cute and stylish iPhone covers! In Boston I see that the iPhone covers are more concentrated on durability. Most of these cute and stylish iPhone covers sold in Japan are less durable.
Yes, Boston sells similar types of covers but I find the quality to be very poor (you can see the glue that they used to stick on the stones) and despite the quality looking poor, they are usually quite pricey compared to Japanese ones I usually find. This cover I bought was only 1,900YEN (20USD)! They offer a great variety of colours and design everywhere in Tokyo/Yokohama for different kinds of phones.
