10 Best Japanese Smart Toilet 2025 in the United States

The HOROW Artistic Bidet Toilet is designed to offer a comfortable and convenient bathroom experience, especially suited for users who appreciate smart features and accessibility. Its ADA chair height makes it easier to sit and stand, which is great for those with mobility challenges. The elongated heated seat comes with four adjustable warmth levels, helping you stay cozy. This model boasts a powerful flush system with dual flush options that balance strong performance and water efficiency.

The built-in bidet includes multiple cleaning modes and a self-cleaning nozzle, providing thorough hygiene after each use. The auto open/close lid adds a hands-free touch, opening when you approach and closing gently when you leave. The package includes a remote control and all installation accessories, but the toilet is quite heavy at over 115 pounds, which might require professional help to install.

If you want a reliable smart toilet with essential luxury and accessibility features but don’t necessarily need every possible function, this model could be a solid choice.

The Kohler K-5401-PA-0 Veil Comfort Height Skirted One-Piece Elongated Dual-Flush Intelligent Toilet offers a variety of features that make it stand out in the Japanese smart toilet category. It includes essential functions such as bidet functionality, a heated seat with adjustable settings, and self-cleaning nozzles. The bidet system offers both front and rear wash modes with warm water, and the heated seat ensures comfort during use, which is excellent for colder climates or those who value warmth and hygiene. Additionally, the self-cleaning function uses UV light and electrolyzed water to maintain cleanliness, reducing the need for manual maintenance.

The air dryer and built-in deodorizer enhance the user experience by providing post-wash drying and reducing odors, respectively. An LED-lit night light helps with visibility during nighttime visits without the need for bright bathroom lights. The toilet also features a dual-flush technology for water conservation, allowing users to choose between a full or partial flush, and it connects directly to the water supply with a tankless design for a sleek, minimalistic appearance. The remote control and touch-screen LCD make it easy to operate, and the motion-activated, hands-free opening/closing of the cover adds to its convenience.

Despite its many features, at 86 pounds, it is relatively heavy, which might make installation challenging without professional help. Additionally, some users may find the touch-screen remote control complicated at first. With its high functionality, the price point could be a consideration for budget-conscious buyers. This smart toilet is best suited for those who appreciate advanced features, high hygiene standards, and are willing to invest in a premium product for their bathroom.

The Casta Diva Smart Toilet (model CD-K030PRO) is a solid choice if you're looking for a high-tech toilet with Japanese-style features. It offers a powerful flush with a 1000g MaP rating, which means it cleans effectively without relying on strong water pressure. The built-in tank also makes installation more flexible. The bidet seat is user-friendly, activating automatically when you sit down and offering several warm water cleaning options including massage modes, all starting instantly for comfort. It also has self-cleaning nozzles to keep things hygienic before each use. The heated seat adjusts to the room temperature across five settings, which is great for year-round comfort, though this feature is off by default and requires manual activation. A foam shield helps prevent splashes and odors, making the bathroom fresher. Other useful features include a warm air dryer, an auto deodorizer, and a soft night light, which adds convenience and comfort.

The toilet lid opens and closes automatically, and the foot sensor allows for touch-free flushing, helpful for maintaining hygiene. The remote control makes adjusting water pressure, temperature, and other functions easy without bending or reaching. On the downside, while the foam shield is innovative, it requires users to prepare a liquid solution, which might be a bit of extra effort. Also, some advanced features like intelligent temperature adjustment need setup before use. The toilet is floor-mounted and ceramic, with a sleek black design that fits most modern bathrooms. It might be a bit heavy to install due to its weight (about 96 pounds).

This toilet is well suited for those wanting a fully featured, easy-to-use smart toilet with strong flushing power and good hygiene features, especially if you appreciate touch-free and automated functions. Be prepared for some initial setup steps and minor maintenance like foam preparation.
