Yolni Inc. (Headquarters: Chiyoda-ku, Tokyo; CEO: Erika Okide; hereinafter 'Yolni'), a member of StartupSide Tokyo (hereinafter 'SST')—an incubation facility operated by Tsucrea Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; CEO: Hideki Suzuki; hereinafter 'Tsucrea')—has launched general sales of its IoT safety accessory 'Yolni' through its official online store.
This product won the Grand Prix in the 2023 'Tokyo Made Movement,' a product development support program hosted by the Tokyo Metropolitan Industrial Technology Research Institute. After gaining significant attention through crowdfunding campaigns, the product is now officially available to the general public.
With the start of general sales, a dedicated customization page titled 'Design your Yolni' (https://yolni.jp/shop/) has been launched on the online store, allowing customers to freely combine the 'device body' and 'premium leather strap' according to their fashion and lifestyle, and intuitively add them to their cart.
Background of Development: Founded on the Desire to Eliminate Nighttime Anxiety
'We want to eliminate the feeling of 'anxiety' when walking at night.' Born from this strong conviction, Yolni is a hardware startup originating from Akihabara. Yolni focuses not only on actual 'dangerous' situations but also on the everyday 'anxiety' many people feel during commutes or returning home at night. By combining technology with high-quality design, Yolni aims to create a society where everyone can walk confidently and safely.
Sales Overview
- Release Date: June 12, 2026 - Sales Location: Yolni Official Online Store (https://yolni.jp/shop/) - Price: Device: ¥18,700 (tax included), Premium Strap: ¥2,700 (tax included)
Yolni: A New Safety Choice Adults Want to Wear Every Day
Traditional safety buzzers and GPS devices are often perceived as 'for children' or 'obvious safety gear,' creating a psychological barrier for adults to carry them daily. Yolni aims to become a safety product 'chosen as an accessory' by emphasizing three key aspects:
- Minimalist, gender-neutral design - Seamless integration into bags and outfits - Reassurance through functionality only when needed
Supporting Daily Peace of Mind with Three Modes
By pairing the accessory-style device, which can be attached to bags or clothing, with a dedicated smartphone app, Yolni supports daily safety through three approaches: 'when anxious,' 'in emergencies,' and 'during normal times.'
- When Anxious: Pressing the button triggers a ringtone from the smartphone, allowing users to signal caution or pretend to receive a call - In Emergencies: Pulling the pin and pressing the button shares the user's current location (GPS) via LINE or SMS with friends or family. Returning the pin immediately stops the sharing - During Normal Times: AI analyzes walking data and issues alerts based on risk levels
Premium Materials and Customizable Color Options
The device body features a precision-machined metal finish for a refined look. The dedicated strap, developed specifically for device attachment, uses high-quality leather and is designed to harmonize with lifestyle goods and apparel. It can be easily attached to various locations such as bag handles, belt loops, or as a phone strap. To suit diverse fashion preferences and age groups, a wide range of color options is available.
Feedback from Early Supporters: High Praise for Design and Practical Functionality
Customers who received the product through crowdfunding have shared positive feedback on social media and blogs:
- Design and Philosophy Resonating with Adults: 'Rare high-quality design for adults,' 'Appreciate the gender-neutral concept that transcends age and gender, not limited to young women'
- Exceptional Practicality: 'Features like sharing location continuously while muting the buzzer to avoid provoking attackers are realistically useful'
- Gifting to Loved Ones: Chosen not only as personal protection but also as gifts for 'new life starting in April' or 'entrance ceremony presents' for loved ones
Notably, nearly half of the crowdfunding supporters are male. The gender-neutral design and the concept of 'eliminating nighttime anxiety' have resonated widely across demographics.
