They have very good customer service and fast worldwide delivery!

Just got my SARB017 and I love it...order Wednesday and got it Saturday, super fast shipping considering is coming from Japan. Thank you Kobayashi-san 

Utterly amazing! I managed to order a SARB017 Alpinist on Friday (10:22am) and it arrived, at my house, on a Sunday at 2:15pm!!!

I'm utterly floored! And I can't stop looking at this beautiful timepiece on my wrist.

The service provided by Kobayashi-san is second-to-none. I no doubt will be buying from him again :)

I cannot give enough praise!

I really can't say enough about SeiyaJapan! Great service, great price and outsranding service. The shipping and packing are top standard .
Made three different purchase and all three have been outstanding. All three seikos lineup with the bezel, package included a polish cloth and catalog. Top quality service.
SeiyaJapan has become the first place I check online when buying a watch.

That was fast!! I ordered a Seiko Alpinist on Tuesday and it showed up Thursday. In the box still in the manufacturer wrapping, it had never been touched. I also got a Seiko catalog and a cloth with the SeiyaJapan logo on it. I guess 
for wiping it down or cleaning it. From Japan to California in two days, I'm impressed. Not to mention even with shipping it was cheaper than anyone on Amazon.

Excellent range and personalised service by Seiya. Highly recommend supporting Seiya and his range of Japan made watches.

I really can't say enough about Seiya-san! Great friendly service, was in contact throughout the process. Only took 3 business days to reach Australia which was amazing. The pictures of the SBDC051 don't do it nearly enough justice. I haven't been able to keep my eyes off of it.

Super!!!

Perfect service! Very fast shipping, stunning watches.

Great service from Seiya. Super fast shipping via EMS and the communication along the way was superb too. Highly recommended

Seiko Alpinist Amazing watch for this money! Great customer service and communication from Mr Kobayashi! Delievery was super fast! Definitely will order again!

Excellent service, fast shipping and brilliant watch. Nice person, thank you Seiya-san

Having bougth 3 watches already I have nothing but positive feedback for Seiya San. JDM-watches are by far more interesting and visually better looking than what is normally available in Europe, and Seiya's stock is superb. Quick handling, no trouble whatsoever, watches are genuine. Seiya is my preferred option for JDM-watches.

Outstanding shipping and excellent website. It may take a day or so for emails to be returned, but Japan is a long way from the US and I believe he is very good on getting back to me on email.

I am so happy with my new retro style Seiko watches. The price-performance ratio is amazing.
The only improvement could be logo in kana or kanji. Latin seems so vague :-D

And of course very good service and delivery from Seiya. Thanks)
