Purchased in the US around 2019. Used for 1 year. Batteries not included. Everything in the pictures is included. It should work fine in Japan if you have Wi-Fi, but I don't think it supports Japanese. I believe you'll need a bridge like Alexa or HUE, but please confirm the detailed usage before purchasing. The included box is sturdy, so I will ship it with minimal packaging. Instant purchase is welcome. # SmartHome # AutomaticLock # SmartLock Price reduced to 500 yen on 2026.01.
