All rooms feature semi-double beds; quiet, clean, and convenient for business.

The hotel, located just a 1-minute walk from JR Sobu Main Line Shin-Koiwa Station, offers a comfortable space to relax and unwind after a long day. All Rooms are equipped with Simmons semi-double beds, ensuring a quiet and clean environment for rest. The first-floor restaurant "jonathans" serves a morning buffet.

  • It’s closer than staying in the city center, and if you Reserve early, the price feels reasonable. This was my second stay, and I booked a Multiple Night Stay with breakfast included. There is a Jonathan’s on-site. The staff are very friendly, with great greetings and service. I recommend the breakfast plan. I will Reserve again next time.

  • The Room key card wasn’t working properly, but when I told the front desk, they came right away. The issue was resolved quickly, and their wonderful support when I was in trouble really warmed my heart. This was my third stay, and I’ll be back again! Thank you very much.

Notice from the Accommodation

  • Notice of Water Outage Due to Plumbing Facility Inspection (10/14, 12:00–14:00)

    Thank you for choosing Smile Hotel Tokyo Shin-Koiwa.

    Due to an inspection of the rooftop elevated water tank, the water supply in the hotel will be unavailable during the following time period.

    Date & Time: Wednesday, October 14, 2026, 12:00–14:00

    During this outage, in-room water facilities such as the shower, washbasin, and toilet will not be available.

    We sincerely apologize for any inconvenience this may cause and appreciate your understanding and cooperation as we work to maintain safe facilities.

    *Please note that the end time may change depending on work conditions.*

  • We have introduced card key access for our guest rooms!

    To enhance guest convenience, we have upgraded our guest room locks to a key card system.

    With key cards, you no longer need to leave your key at the front desk when going out. When you return, you can go straight back to your room without stopping by the front desk.

    For stays of two guests, we can provide a separate key card for each guest, making it convenient even when you go out separately.

    Door access is now smoother than before, helping make your stay more comfortable.

    We will continue striving to improve our services and facilities so that all guests can enjoy an even more comfortable stay.
