For example, the average price of Mobile Suit Gundam figurines was 6,354 JPY from January to May, up 130% from the annual average price of 2,812 JPY in 2014. Dragon Ball figurines posted a 190% upswing during the same period, while prices of One Piece products jumped by 110%. [...] One reason for the higher prices for secondhand items is the rise in prices for new ones. Advances in manufacturing technology have revolutionized the creation of anime and manga figurines, resulting in meticulously crafted statues that exquisitely capture the unique nuances of each character -- the intricate details of their costumes, the subtle expressions on their faces and their iconic poses. [...] The price of a certain secondhand figurine of Majin Buu, a major antagonist in the Dragon Ball series, has increased from 8,800 JPY 10 years ago to 150,000 JPY. Mandarake, which sells toys and books, also reports a shortage of stock for the character's figurines, including limited editions. The prevalence of streaming sites like Amazon Prime and Netflix has enabled fans abroad to watch anime simultaneously as those in Japan. "Popular works in Japan often gain worldwide popularity quickly," said a Mandarake executive.
