Having bought many boxes from Hiroyuki, I can assure you that the quality has always been at the rendezvous. The boxes slide perfectly and the key cuts are invisible. I like all his boxes but especially the boxes that combine yosegi and walnut .The yosegi marquetry forms a pleasant contrast with the dark wood of the walnut and in addition it is an unusual square format box. I always very much appreciate the attention given in the well-wrapped parcel and with gifts. always a pleasure to offer those you love a box like these, the pleasure of seeing the person trying to open it and when you slip a little message or something, they are amazed! thank you very much Hiroyuki.

I purchased 2 Puzzleboxes, because I always wanted to have one as a kid. They arrived in Germany quickly and they are amazing. They slide free and easy and if you don't know where to look you can't see the sliding parts. These boxes are like art. Beautiful woodwork.

This is a beautiful box, cleverly constructed with nearly invisible lines. Arrived safely from Japan to California.
I had intended to give this as a gift, but ended up keeping it myself. I would definitely recommend this to any one wanting something unique and special.
And trying to open this up without looking at the instructions was fun and challenging.

Excellent work as always; thank you.

We purchased the 27 step Yosegi 5 sun puzzle box for our son. The box is intricate and beautiful, and works smoothly and perfectly....the feel and sound of the sliding tabs are a pleasure and our son was delighted! The packaging was not only secure, but was also lovely to look at. And the service was exceptional: we ordered the box on January 2nd and were astonished to receive it (in the US) on January 5th. Thank you very much Mr. Oka.

I want to compliment you on the workmanship and its presentation. The way it was shipped, the packaging and the attention to detail is most appreciated. From the beginning of the purchase to the delivery and preciseness of the box movement, is truly of the utmost high quality. I hope to make another purchase from you in the near future.

Very nice box, excellent craftsmanship and very fast shipping to Europe, thank you very much!

Thank you very much ! Great quality, fantastic design !
