As summer draws to a close, are you troubled by accumulated fatigue from the scorching heat and autonomic nervous system imbalances caused by air conditioning—what's commonly known as "summer fatigue" or "lingering summer fatigue"? This season, when not only individuals but the entire team tends to feel somewhat stagnant, is precisely when a special event is needed to completely refresh mind and body and strengthen team unity.

It stands in a quiet alleyway in Asakusa.SAUNALAND ASAKUSAThis is a high-quality private space that shields you from the hustle and bustle of the city. We will escort you in a gentlemanly manner for a sophisticated "sauna team building" experience, perfect for the end of the first half of the year, the start of the fall season, or a special anniversary date with your dear friends or partner.

The lingering summer heat brings on fatigue. Why a team-building session in a wood-fired sauna now?

In 2026, with growing interest in QOL (quality of life) and well-being, business and private gatherings are evolving from "drinking parties to relieve stress" to "healthy experiences that improve physical well-being and deepen dialogue."

A new norm to replace drinking parties: "Naked communication" that dramatically increases psychological safety.

At social gatherings centered around alcohol, conversations tend to be dominated by the loudest voices, and fatigue can linger the next day, reducing work efficiency. However, in the extraordinary setting of a private sauna, suits and titles are shed, and everyone faces each other as equals. Sharing the same heat and quietly sweating together fosters psychological safety within the team.(The confidence that everyone can speak without fear of rejection)This dramatically enhances the ability to communicate and creates the perfect environment for genuine, heartfelt dialogue.

Resetting air conditioning fatigue and autonomic nervous system imbalances: The science of "well-being" to boost work productivity.

Much of the fatigue you feel during the lingering summer heat is due to autonomic nervous system dysfunction caused by the temperature difference between air-conditioned indoors and the harsh outdoors. Alternating between hot and cold baths—raising your core body temperature efficiently in a private sauna and then tightening it in a cool bath—dramatically improves blood flow and relieves mental fatigue. The feeling of well-being you experience after a sauna will maximize your concentration and productivity the next day.

The appeal of SAUNALAND ASAKUSA's high-quality "private sauna for large groups."

While there are many private saunas in Tokyo, facilities that offer a truly authentic sauna experience using a wood fire, especially for groups, are extremely rare.

A truly authentic wood-fired sauna that will surprise you with how easy it is to breathe, and a spacious "bathtub" that female guests will also love.

Our star attraction, the wood-fired sauna, is remarkably breathable, unlike electric heaters which can leave your skin feeling dry and irritated. The natural air circulation and moderate humidity created by the wood fire allow even those who don't usually enjoy saunas to comfortably relax for extended periods. In addition, we have a spacious bathtub (bath) separate from the cold plunge pool, where you can soak up to your shoulders. Female guests who are concerned about getting cold, as well as first-timers, can relax and enjoy a high-quality spa experience with peace of mind.

Men and women are welcome in the sauna while wearing swimsuits. A borderless space that fosters a sense of unity within the team.

SAUNALAND ASAKUSA is a completely private space where men and women can enjoy together as long as they wear swimwear. It's perfect for couples and groups, as well as for team building in the workplace where men and women work together, allowing everyone to share time together regardless of gender or age. Spending time without worrying about being seen, discussing the timing of self-löyly and your preferred temperature, will create memories that are deeper than any banquet at a high-end restaurant.
