This time, my child wanted to play in the gym, so I made a reservation here.This is a valuable campsite as there are very few campsites where you can enter the hot springs for free.The hot spring was an 11 minute drive away.It was cloudy on the day of the reservation and rained the next day.There is a cancellation fee for this, so I decided to just enjoy the day itself.It was raining the next day, so I gave up on staying in a tent.It's easy to spot when you're driving by because there's a Chirumitsu flag hanging out at the entrance.There is another flag posted at the campsite, but the site with the gymnasium is at the entrance with the green building.During check-in hours, there will be a staff member at the parking lot, so just tell them the name you reserved and they will drive you directly to the school grounds.This is a free site with no divisions.Since it was high season, the car was moved to the parking lot after unloading.A tent will be pitched all around the schoolyard, leaving a space in the middle. I thought that if I didn't have a car, I could play ball in the schoolyard, but I decided against it because it would be dangerous.The shade of the trees doesn't seem to drain water very well after rain, so the pegs tend to fall out in some places.It was a little muddy in some places.Depending on the direction of the wind, I could smell the fertilizer coming from the neighboring field.The washing area was clean and felt good.The toilet and shower are opposite the door.It was difficult to use the toilet because the passageway was narrow and there were people waiting to take a shower in the evening, but it was helpful because the toilet had a Western-style faucet.It was a unisex toilet, not a women's one.There was one for men.I looked at the free shower room and it was new and clean.I didn't use it this time, but it seems like it would be nice to use, and I'm glad it's free.I didn't take pictures of each place, but there was a water area next to the dark brown building, and the place looked new and clean overall.The gym is hot on a hot day.This is a gymnasium with the size of one basketball court.You can come and go as you like without making a reservation.Both children and adults play with various toys, so it can be dangerous if you are not careful in the gym.The lights in the gymnasium are not on.We recommend playing before it gets dark.This time, to escape the rain, I cleaned up before dark and went straight to the hot springs without checking out.It was my first time at Tamana Onsen.The parking lot seems to be separated for guests and day visitors, and the hotel staff came out to the parking lot.I entered the room after telling the front desk that I was staying camping.The indoor bath was a good temperature.The hot water temperature in the sleeping bath and the long open-air bath is low.I think there were about 5 showers.Shampoo and body soap were provided.There were 3 hair dryers, 2 fans, and 2 toilets in the changing room.Coffee milk and R-1 were sold in bottles at the vending machine.We just pitched a tarp, lit a bonfire, played a lot, ate camp food, and felt refreshed and satisfied in the hot springs.All trash was taken home.I brought firewood with me, but I didn't know where it was sold.The ash dump was located in the gymnasium.Many campgrounds allow cancellations in the event of rain up to the day before, so I overlooked this when making the reservation, but I'm glad I was able to enjoy it on the day itself.
