Don't underestimate the fact that we specialize in popular theater! An underground empire hidden in the Kawagoe residential area!Hotel Sanko stands just past Kawagoe's crowded shopping street.Many of the facilities where popular theater performances are held have a somewhat somber appearance,Surprisingly new look.Once you enter the entrance, go up the escalator to the front desk.Even though it is a short course of 3 hours, I am happy that it comes with a towel ☺️[Dry sauna]Width 5.5m, depth 4.5m, height 2.8cmIt has a complicated two-stage structure,There is a dimly lit cage seat in the back!The heat source is a stone convection type and the temperature is about 95 degrees.Because the radiant heat is not strong,The temperature feels extremely high! !Because the style does not have a sauna mat on the seat, your feet may get extremely hot.Because the seat doesn't seem to have a structure that can be opened and closed,Maybe it's a little oily?The walls and floor are badly damaged and burnt in some places, giving the room a historic feel.It seems like there was a TV a long time ago📺[Water bath]Fan-shaped piece of 2.5m, depth 60cmThe thermometer seems to be broken, butThe temperature feels like 15 degrees, which is pretty chilly✨[Organized place]There are 3 chairs in the bathroom 🪑You can also rest in a bedrock bath-like area where water leaking from the super jet flows onto the floor 🤤You can rest on the chair 🪑 in the changing room!It's also nice that the changing room has a paper cup type water server!【bath】It seems like a health land-like facility,We have a wide variety of variations,Since the bathroom is relatively compact, the conductor is also good!⚫︎Radon hot waterThere is a vibra with a boiling water setting of about 42 degrees!It feels good to see the cold water leaking through the caulking from the boundary with the cold bath🤤⚫︎Change hot springIt seems to change every three days.Today is the forest hot spring🌳What is important is its concentration,Just one scoop and it's really strong like matcha! ! 🍵Transparency about 5 cmIs it about 20 times more concentrated than home-use bath cream?((((;゚Д゚))))))))It seems to be highly effective, butBest of all, the scent is strong! !Bath salts were also sold in bottles at the front desk lol.⚫︎Komyosen carbonated springThe bathtub is 3.5m long and 1.7m wide.The raw stone produced in Okayama Prefecture in the box enhances its efficacy! !Because the bathtub is made of cypress, the carbon dioxide concentration is quite high! !⚫︎TsuboyuThere is one pot bath with a diameter of about 1m.It has become an insensible hot spring,It's also nice that the overflow hot water is used as a footbath.⚫︎Super JetA bathtub that closely resembles the New Wing's circular jets.⚫︎Full body showerThe power and temperature are high,Unless you are very stiff, you are bound to give up halfway through![Rest area]As with any facility that hosts popular theater,Kawagoe Sanko also has a vast rest area with multiple floors! !Most people usually take a break in the snack area on the second floor, which has a TV and is closest to the bathroom entrance.The third floor is where the popular theater is held.The songs and shouts of the program echoed,It has a great atmosphere! !There may be some desks and chairs, soYou can take a break here.A Japanese food space with an atmosphere,There seems to be a private dining room, soThe Japanese atmosphere is irresistible! !Also, although it is difficult to understand at first glance,You can go back and forth between 4F and B1F using the elevator!(It's easy to misunderstand that the 3rd floor stairs are closed to traffic lol)To be honest, it is no exaggeration to say that the B1 floor accounts for one-third of the charm of this facility.In that vast underground space,A rich collection of manga over 10,000 volumes!(I'm happy to have the latest issues from rare manga to maniacs such as Kengan Omega ☺️)And there is an unnecessary amount of reclining space! !In addition to being divided into sections for men and women,Physics unique to Showa hot spring facilities? There is also a multi-view theater room equipped with a Dolby system! !There are several giant Yogibo cushions with a diameter of 1.2m and a weight of 30kg, and plenty of sofas, so there is no shortage of space to relax! !The best part is the semi-private nap room where you can charge your batteries.There are also exercise bikes and a game center! !Moreover, one quarter of the rooms are vacant, which means there is a lot of room for growth! !It's really a shame that this fulfilling space is sparsely populated! !The location is not very conspicuous,Although there may be some aspects that lack appeal,Being able to use this for 3 hours for 850 yen is quite impressive! !Also, maybe it's because there are too many other facilities on the 4th floor.Although it is quite overshadowed,There are probably around 1000 comics.(It might be interesting to take advantage of the fact that the shadow is thin and put away some weak books by doujinshi. I think I'll donate about 10 books.)There are a few recliners,There is also a spacious balcony with a cradle! !There is also a nap space for paid reserved seats.
