What does “JIYUU” mean?
JIYUU is the Japanese word for freedom. To us it means we’re free to do the things we love and show our committment everywhere we go. Working out (or just working), surfing, diving, paragliding, abseiling, there are no limits to what you can do with JIYUU.

What are JIYUU rings made from?
JIYUU Athletic Wedding Rings are made from 100% medical grade hypoallergenic silicone rubber (non-toxic and BPA free). If you have any question about allergies or irritation please talk to your GP.

Where is JIYUU located?
We’re founded and currently situated in sunny Esperance, WA. 

How do we contact you?
You can send an email to and a member of our team will get back to you. We aim to respond to all emails within 24 hours, however we are only small so please be patient and we will respond to your query as soon as we possibly can! Our postal address is PO Box 311, Port Hedland WA 6721.

How soon will I receive my ring?
All parcels are sent the next business day after the order has been received. Standard shipping is estimated to take 3-4 business days within Australia and 7 business days to metro NZ. Express post usually takes 2-3 days within Australia or 5-6 days to NZ. Unfortunately we cannot guarantee next-day delivery with express post as our rings depart from our headquarters in Esperance.

My ring doesn’t fit! How do I exchange it?
Head on over to our returns page for details. If you have any further questions, please send an email to and we’ll respond asap.

Do JIYUU rings stretch?
They do stretch, this is to ensure that they can slide up and over your knuckle. Under normal wearing conditions they should retain their shape after being stretched.

Can I wear my JIYUU ring all the time?
Sure can! We do recommend that you dry it well after being in water, as moisture can get trapped under the ring and cause minor irritation. If your ring does fit very snugly, you might also need to take it off at night to allow your skin time to breathe if you notice the skin underneath becoming dry or irritated.

What sizes do you offer? What are the dimensions?
Men’s rings have a width of 8.7mm, women’s rings have a width of 5.5mm. For full sizing details, check out our size guide here. In the men’s range we offer sizes 8 to 14, in the women’s range we offer sizes 4 to 9. We recommend buying a size up if you’re in doubt.

I’m a ½ size. What size should I buy?
We recommend buying a size up (eg. if you are a 6 ½, try a 7) to ensure the ring doesn’t fit too snugly.

Can I resell JIYUU rings at my gym/club?
Please send an email to and we’ll be in touch!
