Recent statistics show the Land Cruiser at the top of the theft list for several years running (about 30% of the total), followed by the Alphard, Prius, Crown, and Lexus RX/LX. Popular models with strong overseas demand and newer high-value cars are especially targeted.

For these cars, layered defense that "makes thieves spend time and give up" is effective. We combine start-prevention types, "won't-let-them-open" types, alarms that alert immediately, and GPS types that show the location if the worst happens—tailored to your budget and car. If you own one of these models, we recommend consulting us early.

If protection against the CAN invader is your priority, we most recommend the IGLA series, which keeps directly monitoring regardless of the vehicle's communication state, and in particular AUTHOR ALARM with its dedicated CAN invader operating mode.

In addition, the latest statistics show that the most common location is "private homes," at 45.2% of the total — the highest share on record. In practice, you cannot assume that parking at home makes you safe. There is also a strong regional concentration: Aichi, Saitama, Kanagawa, Ibaraki and Chiba together account for roughly 55% of all cases. If you live in the Kanto area, it is wise to prepare on the assumption that yours is a high-incidence region.
