KAIZEN / 改善
Kaizen began with a simple question: what if everything carried in a wallet had a better place?
Card storage is distributed to help avoid one thick stack. Full-length notes stay flat. Coins, a travel pen and small travel essentials are kept secure and easy to find.
Beauty. Form. Function.
-
Beauty
Leather chosen for its character, texture and how it develops with use.
-
Form
Compact proportions designed to feel considered in the hand and pocket.
-
Function
Every slot, pocket and detail must earn its place.
KISETSU / 季節 / SEASON
Kisetsu means “season” in Japanese. The name reflects something simple: what we carry changes.
It changes with our routines, journeys and different stages of life. We create wallets for those different ways of carrying, guided by the same principles: Beauty, Form and Function.
Seasons change. The principles remain.

Let customers speak for us
from 149 reviewsDispatch and shipment was very fast. Wallet arrived in good condition too.
Beautiful leather with a great minimalist design.
Fast delivery,great communication
The model of the wallet is perfect - exactly what I was searching for. Quality is good, although it seemed to me the leather was thicker than it is.
It's great to have a video demo allowing me to have an overall outlook of the wallet. Shopping experience is very easy to shop.
Love the vintage leather brown crazy horse leather, they look like saddleback and vintage outlook. The Kaizen is a wallet which has great storage, multiple compartments making it very easy to organise. It's easy to retrieve from the pocket due to the edge cut design. Smart!
Lovely experience, the customer service responds fast via email and the quality of the wallet exceed my expectations. Fast delivery too for Singapore, I got it in 2 days.
Love the orange wallet! It makes a great gift during this season. I bought a few of these for my company gathering and everyone was talking about how lovely the colour is matching with the new iPhone colours. I believe this is a limited run batch. Get yours before it runs out.
Compact and complete.
I took the Shinkai with me on a recent trip, absolutely loved it. The secure pop-up system made airport check-ins quick, and I could keep some folded bills tucked behind. Light, secure, and stylish.
Got mine a month ago, the button is smooth, and the cards never slip out accidentally. I keep 4 cards inside and a few folded notes in the outer sleeve, just the right amount for everyday use.
That click when I press the button to release the cards, absolutely satisfying! The holster feels super solid in hand, and the mechanism works flawlessly. I keep a few folded bills in the cash slot, which is perfect for quick errands.
Natsu a very travel friendly wallet, small compact and just keep everything tight, I will recommend at least putting 4-5 cards in them to ensure cards don't fall off easily
I can carry cards, a bit of cash, and coins without it feeling bulky.
Bought the Natsu and I needed something small to keep my extra cards in my car whenever I need them. This is good, small and the full grain caramel color just stands out in my car.
Built From Feedback. Designed for Real Carry.
Kisetsu Leather started on Kickstarter with the launch of our first wallet, the Haru Wallet. That campaign marked the beginning of our approach to design - creating wallets that balance beauty, form and everyday function.
Inspired by the Japanese word for “seasons”, Kisetsu reflects the idea of change, improvement and thoughtful design. Each wallet is created with a different way of carrying in mind, from slimmer pockets to better organisation and travel-ready details.
Since 2015, we have launched over five Kickstarter wallet campaigns, shaped by customer feedback and everyday carry needs. From card access and coin storage to RFID protection and compact designs, our goal is to make wallets that look good and work well in daily life.
