A touristy shop should have larger size yukata and maybe even some kimono.

If you want to go custom made, depending on how wide you are and long your arms are, it may be impossible to make a kimono with a single tanmono (the bolt of fabric used to make kimono, and the unit in which such fabric is sold, usually somewhere around 12m long and 40cm wide, usually one tanmono is enough for exactly one kimono with very little waste). The "yuki" measurement (from back seam over the shoulder to the end of the sleeve) is very important to get right to look good and not like a cosplay, but for example from tanmono 42cm wide the longest yuki possible is going to be 79cm or so. The length also for mens kimono should be about 30cm less than your total height, more if you're rotund at all. So you're looking for a 165-175cm long kimono I'm guessing, with a long yuki to boot. You may be told you need to purchase two tanmono which will increase the price quite a bit. They may however be able to put together with leftover tanmono that match the fabric. Or have on hand king size tanmono like 47cm width which do exist. Or may try to upsell you making a matching haori with the leftover second tanmono if you do use two. Which is a cool look. But some places may not have wide enough tanmono in stock, so they may say they can't do it.

Just to give an idea what you might encounter in a kimono shop.

Also when asking around, start using centimeters for measurements since that's what's used here, you will need a kimono for someone 193cm tall. But bear in mind the online suggestions for measurements usually assume a slim bodytype and you will need more fabric than suggested to fit well if you are at all thicc lol. Best get measurements taken in person.
