Business trip to Osaka in Summer What to wear?

Kimono

Is your company following cool biz? If so, light trousers and short sleeve shirt will do.

It's still ivory.

You're recruiting subjects your majesty?


You dress like what?

Depends on with whom you are meeting and where. Some companies follow a "relaxed" summer dress code to cope with A/C usage. This means no ties, jackets, and possibly short sleeve shirts. Although you will never see a senior manager dressed like that. The "no tie" rule is common on really hot days. Why not consider a linen suit in more conservative colors? Navy, gray, and black are common. I'm sure there's a lot of laughter and comments surrounding your choice of a white 3-piece suit for business apparel. Perhaps it's ok for a night out, but for a business meeting? What are you selling? Viagra for the night clubs?

Don't wear "Cool biz." That's for government employees and for people who only work inside the company office. Wear a suit and a tie in conservative colors. You're right that it is crazy hot in July, so make it a very light suit, such as linen. Most businessmen who go out to drink after work do not change into anything special, so neither should you. But you'll probably be hanging out in smoky bars so you're going to need to give the suit a day or two to air out.

Can you look good in a suit without a tie? If you can, maybe you can do that if you get a feel for the clients first. On your first meeting, dress as conservatively as possible.

TLDR:

2 or 3 light, conservative 2-piece suits. Wear ties unless you don't have to. NO IVORY!!

I should just add... that is the safe answer, and in Japan the safe answer is the Right Answer. But, if you want to take the leeyway (which I think you do, since you usually wear a 3-piece ivory suit), you could just wear a blazer and chinos. I see a lot of foreign businessmen in Osaka dressed that way. But again the best answer is to dress conservatively and in light summer fabrics.

It is ungodly hot in Osaka in summer. Not quite as terrible as Kyoto or Nara, but it frequently goes over 100, and the humidity makes it worse. I recommend a suit in conservative colors but in a fabric such as linen or fresco. It won't help a lot, but it will be better than those poor salarymen wearing wool and polyester (and more stylish than the dopes forced to go with Cool Biz). If necessary, carry your jacket and roll up your sleeves. Just don't forget to wear a T-shirt: your actual shirt will soak through in less than a minute if you don't have that extra layer covering your skin. In a way, I'm lucky that I'm in secondary education -- nobody bats an eye if I show up in shorts, as long as my shirt has a collar. It also helps me save money on my nicer clothes by allowing me to concentrate on winter items. Incidentally, when riding the trains, beware the dreaded 弱冷車 — mildly air-conditioned carriage. It's no fun.

so jealous.
iwent to osaka (and surrounding cities including tokyo) a year ago.
you'll have a wonderful time.

try the local okonomiyaki.

You have an Osakan mindset indeed when you consider Tokyo a "surrounding city" of Osaka. FTFY.
