  • This was my first ti...

    This was my first time at Hawaiians, and I chose this Hotel because it is the closest to the pool. You can go in and out of the Hotel in your swimsuit, and it was convenient for getting anywhere within Hawaiians. They also replaced our towels a few times. The Room was very clean, and both breakfast and dinner were delicious. Because there are only a small number of rooms, the front desk is also small, so there was a bit of a line for check-in and check-out procedures.

  • We had a comfortable stay.

    Access to the pool was extremely convenient. We went straight from our Room to the pool in swimsuits and barefoot, without carrying any belongings. After playing, we returned directly to our Room and took a shower. Being able to use it this way is a distinctive feature of this Hotel. Also, it was very comfortable because access to everywhere was excellent. The dinner and breakfast buffets were not too crowded, and we enjoyed delicious meals. We would like to stay at this Hotel again next time.

Remarks
Edo Romance “Yoichi” Soaring ceilings, white walls, black-lacquered pillars, and well-worn antique wooden floors. This Onsen Facility recreates the atmosphere of Edo by drawing inspiration from Edo-period streetscapes and bathhouses. With a total bathing area of 1,000 m² for men and women combined, it is the world’s largest open-air bath. The name “Yoichi” comes from Ise no Yoichi, who opened the first public bathhouse in 1591 in the early Edo period. In addition to excellent water quality and abundant hot-spring flow, you can enjoy an Onsen experience unlike any other through a variety of productions that let you fully immerse yourself in Edo ambiance. While soaking in the open-air bath, you can watch scenes of stylish Edo-period parlor entertainment through shadow puppetry. Accessible via a connecting passageway from Monorista Tower.
