Boutique Sauna ARCH - Tokyo's Mini Bar/Spa HotelBoutique Sauna  

This exclusive find in Tokyo boasts only two private rooms, perched above a mysterious bar that hides on the first floor of a contemporary concrete building. Boutique Sauna Arch overlooks the cobblestone streets of Kagurazaka in the heart of Japan's megalopolis.

Just as a pub is to the Irish, a salon to the Americans, and a tapas bar to the Spanish, an izakaya holds a special place in Japanese culture. It's a "sake shop" often adorned with vibrant red lanterns, where weary workers gather in the evening to unwind and socialize in a laid-back ambiance.

Kunio Maekawa, Tadao Ando, Toyo Ito, and Kenzo Tange are some of the most influential Japanese architects. Their impact on Tokyo's concrete structures can be seen throughout the city.
