Survey Results Summary: Top 8 Latest Trends for June 2026 Chosen by High School Girls

[Trend 1] setlog An app that democratizes 'aesthetic vlogs' with automatic 2-second recordings every hour. It received the highest number of responses (10). By automatically shooting for 2 seconds every hour, a complete record of the day is generated seamlessly as a vlog. It is highly praised for being easy to use even for those who struggle with video editing, and it is rapidly expanding as a documentary tool for youth scenes such as trips and after-school activities. It offers companies excellent opportunities for product placement that naturally blends into authentic daily life.

[Trend 2] Instagram 'Instants' A 'real' sharing feature with no preview and one-time viewing. This new feature allowing users to post directly from Instagram DMs is a hot topic. Photos are posted exactly as taken without confirmation, and friends' posts can only be viewed once, creating a significantly more 'real connection.' It has high potential for corporate campaign measures aimed at delivering authentic and fleeting brand experiences.

[Trend 3] Iron Beads Re-ignited by 'Oshikatsu' (supporting one's favorites) craft in a modern style matching the trendy 'One Horn' interior aesthetic. The ability to handmade practical items like trading card cases using inexpensive materials from 100-yen shops is particularly popular. It has high affinity with collaboration measures by stationery and craft manufacturers.

[Trend 4] Mocchurin (Mister Donut) Mister Donut's 'Mocchurin' series, which previously went incredibly viral on social media in 2025, makes a full return featuring a brand new 'strawberry flavor' on June 3, 2026. Highly anticipated as a top food trend for the summer of 2026, it serves as a strong reference for viral marketing targeting Gen Z.

[Trend 5] Nail Seal Deco The Korean 'aeae style' smartphone decoration using 100-yen shop materials has officially landed in Japan. Sticking nail seals around the iPhone camera is spreading rapidly due to its extreme ease. It shows substantial promise for promotions by cosmetics and smartphone accessory brands.

[Trend 6] Red Cheese Stick A Korean gourmet hit originating from Shin-Okubo. The combination of sweet and spicy yangnyeom sauce and mozzarella cheese is gathering immense attention from high school girls as a prominent street food spot. It can be utilized effectively for food-tech and inbound PR appeals.

[Trend 7] Yamanote Line One-Round Walk A challenging activity to walk all 30 stations of the Yamanote Line over 14-16 hours has become a secret boom. Eating local food around the stations makes it an enjoyable, content-rich event for friend groups. It can be used for strategic tie-ups with restaurants along the railway line or sports brands.

[Trend 8] Reframe: Multi angle recorder A short video creation app that shoots vertically and horizontally simultaneously, perfectly solving the 'lack of material' issue. Its efficiency in gathering comprehensive editing materials all at once is highly praised. It has high affinity with influencer marketing for creative apps.

The editorial department highlights the 'SNS/Video App' area, where empathy for the core experience of 'easily recording and sharing real moments' is exploding among users.
