Amazon Prime Day discounts on Sony INZONE Buds and Mizuno fitness chair in Japan

Japan's annual Amazon Prime Day sale runs from July 10 00:00 to July 13 23:59, with a pre‑sale starting on July 7. During the event, Sony's INZONE Buds wireless gaming earphones are offered at a 30 % discount. The earbuds, launched in spring, feature ultra‑low latency (under 30 ms), active noise cancelling, up to 12 hours of playback, and a new glass‑purple colour.

Mizuno's "Le Priece Squat" chair, marketed as a seated‑squat fitness aid, is also promoted in the Prime Day lineup. The device lets users perform squat motions while seated, targeting thighs and glutes, and is positioned as a convenient home‑exercise solution for rainy or hot weather. Both products are highlighted as practical upgrades for gaming and home‑fitness routines during the holiday sales period.
