As an athlete, I always struggled with muscle soreness and fatigue after long training sessions. But ever since I started using this, I've noticed a significant improvement in my recovery time. The minerals in the bath soak penetrate deep into my muscles, soothing soreness and promoting relaxation. I especially love the antibacterial action of the minerals, which keeps me feeling fresh and clean even after a long day on the field. And the best part is that I can enjoy a luxurious hot spring experience right in my own home!

I've always been a fan of hot springs and the healing properties they offer. But since I can't always make it to a natural hot spring, I was thrilled to discover Japanese Hot Spring Mineral Bath. This product is a game-changer for anyone who loves hot springs but can't make the trip. The minerals in the bath soak are just as effective as those found in natural hot springs, providing relaxation, detoxification, and rejuvenation!

How does the Onsen Hot Spring Bath actually work?

The warm water activates the rare hot spring minerals, creating a near-100% replication of a Japanese medicinal hot spring effect. Thermal heat transfers to your core, engaging a detox mode and expanding blood vessels for a stress-free flow of energy, oxygen, and vitamins. This clears blockages, so your body can self-heal, leading to mind clarity, physical relief, and deep rest.

How to use
  1. Prepare Your Bath: Fill your bathtub with warm water, ensuring it’s at a comfortable temperature for soaking.
  2. Add the Bath Soak: Pour a generous amount of the Japanese Hot Spring Mineral Bath into the water, allowing the minerals to dissolve.
  3. Soak & Relax: Step into the bath and soak for at least 20-30 minutes, letting the natural minerals and soothing ingredients work their magic.
  4. Enjoy the Experience: Relax and unwind as the bath helps ease muscle tension, rejuvenate your skin, and calm your mind.
Pro Tip: Use 2-3 times a week for the ultimate relaxation experience, or as needed after a long day.
How it works

The Japanese Hot Spring Bath combines healing minerals and soothing botanicals to provide a revitalizing and therapeutic experience:

Onsen Hot Springs Minerals:
Sourced from Hokkaido's natural hot springs, these minerals, rich in magnesium, calcium, potassium, and iron, promote relaxation, soothe sore muscles, and support overall wellness.
Calcium: Essential for strong bones and radiant skin, it regulates muscle function and promotes skin health when absorbed.
Tourmaline: A semi-precious mineral that emits negative ions, neutralizes free radicals, enhances circulation, and supports healthy, glowing skin while calming the mind.
Thujopsis Dolabrata Branch Extract: From Japan's Hiba tree, it offers antibacterial and antifungal protection, cleanses skin, and provides soothing, calming effects.

As an athlete, I always struggled with muscle soreness and fatigue after long training sessions. But ever since I started using this, I've noticed a significant improvement in my recovery time. The minerals in the bath soak penetrate deep into my muscles, soothing soreness and promoting relaxation. I especially love the antibacterial action of the minerals, which keeps me feeling fresh and clean even after a long day on the field.

Let Me Pretend I’m in Japan for a Minute 🛁

Just pretend I’m in an onsen right now, okay? Like actually steaming my stress away in a traditional Japanese hot spring… except it’s just my tiny bathtub. But let me have this moment.

I tossed in one of these mineral sachets from Onsen Secret, and honestly? I’m soaking my stress away. The scent, the warmth, the whole vibe—it’s giving spa, it’s giving peace, it’s giving me-time. And it doesn’t get more budget-friendly than that.

Highly recommend if you need to escape without leaving your house. ✌️

Felt Like a Spa Day at Home

I wasn’t sure what to expect, but this Japanese Hot Spring Mineral Bath totally surprised me—in the best way. The scent is relaxing, and the minerals made my skin feel soft and soothed. After soaking for 20 minutes, I felt like I had just left a spa. My muscles were less tense, and I actually slept better that night. Definitely adding this to my weekly self-care routine!

Closest Thing to a Real Japanese Onsen at Home

I’ve always wanted to try a real Japanese hot spring bath, and this is the next best thing. The Onsen Secret bath soak truly gives that spa-like, calming experience right at home.

It’s honestly amazing that something like this exists. If you’ve been stressed or just need a little reset, this is a must-try. Don’t wait—grab it before it sells out!

Japanese Hot Spring Bath at Home? Let’s See What the Hype Is About!

Okay, so I’m not reviewing these just yet because I haven’t tried them—but I had to hop on and let you know about these Japanese hot spring bath sachets I got. They're inspired by traditional onsen baths, which are known for their mineral-rich, therapeutic benefits.

I looked them up on the brand’s website, and they’re $26 for just one packet—yep, one! And I got three of them complimentary through Flip. So sometimes, Flip really does come through. 🙌

I’m filming this from beside my bathtub (which is hilarious because I literally just posted the other day about how content creators never have time for baths). But I’m making time this week to try one of these.

It’s super easy—just fill your tub with warm water, drop the sachet in, give it a squeeze to release the minerals, and soak for 10–15 minutes… or longer if you’ve got the time. The effects are supposed to last up to three hours! No idea what those effects feel like yet, but I’ll definitely report back once I experience it.

Fun fact: I’ve lived here for a month and haven’t even used this bathtub yet. That’s about to change.

I’ll keep you posted! In the meantime, have a fantastic day—and I’ll see you on the flip side. 🛁💫

Onsen Mineral Baths – A Spa Experience That Eases Chronic Pain

In Japan, they have these traditional “onsen” baths—natural hot spring baths infused with minerals. They're a big part of Japanese culture and wellness, often visited by tourists and locals alike for their therapeutic effects. Some high-end spas in Dallas even offer onsen-style treatments, though they can be pricey—about $150 per session!

As someone who lives with RA (rheumatoid arthritis), I’ve found these baths incredibly helpful. The hot mineral soak offers relief that lasts for hours, and it genuinely makes a difference in managing chronic pain.

I just received a set of three Onsen mineral bath sachets to try at home, and I’m so excited. At-home onsen treatments like these are such a gift—especially when you can get them as part of a deal or promotion. I haven't tried them yet, but I plan to use one tonight after a long day with my little monsters (a.k.a. the kids!). I’m hoping it gives me the same relaxation and relief I experienced at the spa.

If you're dealing with chronic pain, fatigue, or just need a deep relaxation reset, I’d definitely recommend giving these a try.

Lovely Bath Experience, but Pricey for What It Is

Hello! I’ve been soaking in the bath for a little over half an hour—even though the directions recommend 10–15 minutes—and I have to say, it’s been really lovely. The Onsen bath sachet doesn’t have a strong scent, which can be a pro or con depending on what you prefer. I personally enjoy a more spa-like aroma, so I found it a bit lacking in that department.

The sachet itself is nicely made and seems to contain dried flowers or herbs, which is a nice touch and keeps things tidy—no mess floating around in the water.

While the experience is relaxing and pleasant, I’m struggling to see what justifies the high price tag. At over $50 for a pack of three, it feels steep. There are other mineral bath options on the market that offer similar benefits—muscle relief, detox, relaxation—at a more accessible price point.

If these were priced closer to $5–10 per sachet, or if there were a significant discount (like 50% off), I’d consider repurchasing. Until then, I’ll enjoy what I have but likely won’t replenish at full price.

Still, it does feel good—and that’s worth something. Just not $52 for three in my book. Hope this helps!

Longest Lasting Relaxation I've Had from a Bath

I’ve tried a lot of bath products, but this Onsen at-home hot spring soak delivered the longest-lasting relaxation I’ve ever felt. You just squeeze the sachet under warm water, and it releases mineral-rich goodness that turns your bath into a calming, spa-like experience. I stayed in for 15 minutes and came out feeling completely reset—my body and mind both felt lighter.

Pro: The deep, lasting relaxation
Con: There’s some cleanup afterward, but it's worth it.

Highly recommend if you need a real moment of peace at home.

A Little Slice of Japan in My Bathtub

One of my friends just came back from Japan raving about the onsens—those natural hot springs with mineral-rich water and a whole wellness culture behind them. I’ve always been into mineral baths (Iceland’s are still on my bucket list!), so when I saw this Onsen hot spring bath pack on Flip, I had to try it.

I got a 3-pack, and it even came with a little bag, which makes it perfect for gifting—one is going to my friend as a fun reminder of their trip. The minerals are sourced from Hokkaido, Japan, and they claim to help with everything from muscle tension and circulation to stress, jet lag, and even insomnia.

I will say the price feels a little steep for three one-ounce pouches, but if you’re going to use them intentionally and soak for a while (I do at least 30 minutes), it can really feel worth it. It’s a relaxing way to bring the onsen experience home, especially if you love spa vibes and don’t have a trip to Japan booked anytime soon.

If the price comes down a bit, I’d give it five stars. But if you love mineral baths, this is definitely worth trying!

A Surprisingly Relaxing At-Home Onsen Experience

Would I try this again? Honestly—yes. I was a little skeptical at first, but the Onsen at-home hot spring mineral bath really surprised me. I’ve tested a bunch of bath treatments from Flip, but this one felt unique. You squeeze the sachet under warm water, and it releases what looks like super fine sand or mineral-rich mud. It gave the water that true onsen look, like something you’d find in a natural hot spring.

I soaked for about 15 minutes and genuinely felt more relaxed afterward. The only downside? A little cleanup after the bath—but honestly, it’s worth it for the experience. If you’re into baths that actually do something for your body and mind, this one’s a must-try.
