Chiikawa the Movie: The Secret of the Mermaid Island returned to the number one spot in its third weekend after its placement in second last weekend , according to Kogyo Tsushinsha . Over the weekend of August 7-9, the first anime feature film inspired by Nagano's Chiikawa web manga series earned 1.699 billion yen (10.67 million USD) from 1,147,000 admissions. This was a massive 158.5% increase from its second-weekend gross of 1.072 billion yen (6.77 million USD) on 766,600 admissions. One of the major reasons for this increase in box office revenue is likely the Bon Bon Drop Stickers, which were distributed at theaters since August 7 as the second round of theatergoer bonuses. Bon Bon Drop Stickers are a type of decorative sticker that has become a huge trend in Japan, known for their unique three-dimensional look and clarity. The film's 17-day total gross has reached 6.77 billion yen (42.5 million USD) from 4.69 million admissions, according to Mantan Web . Eiga Crayon Shin-chan: Kikikaikai! Ora no Yokai Vacation ( Crayon Shin-chan the Movie: Very Bizarre! My Yokai Vacation ), the 33rd installment in the Crayon Shin-chan anime feature film series, fell three spots to sixth in its second weekend.
