Question 1

No confirmation mail from the golf course.

Accepted Answer

Tee time bookings for golf courses will call most bookings directly to the golf course to make your bookings. When making a booking by phone, I will ask them for getting various information about the golf course.
In the case of bookings by phone, the golf course will not send me any confirmation email. On the contrary, I will call the golf course to confirm your tee times 2-3 weeks before you play.

In some cases, bookings are made via the Internet.
If I make a booking online, I, as the reservation agent, will receive a confirmation e-mail (in Japanese) by e-mail.
In both cases, there is no confirmation email from the golf course for you, the player.
I will send you a confirmation email that I have booked your tee times.
Please save my confirmation email for future reference.

Question 2

Please give me the full names of the players.

Accepted Answer

Please let me know the full name of everyone who will be playing so that I can register the names of the players who will be playing on your tee time with the golf course. I will inform the golf course of those names and have them registered. On the day of your golf outing, please register at the reception desk with your name.
When you do so, please tell the staff of the course who you are and what time your tee time is, so that he at the reception desk will know who you are. The applicant's name is Yano Yoshihisa, and the player is your name.

Question 3

Is it possible to play golf alone?

Accepted Answer

Although I receive many inquiries from single golfers, I do not accept applications to play alone. This is because the golf course does not accept single golfers.

Japan is currently experiencing a golf boom, and golf courses are finding it very difficult to get tee times.  Usually they accept at least 3 or 4 golfers in a group, and many golf courses allow 2 golfers to play in combination with other guest players.
If you still really want to play alone, you can play with two people, counting me in the count, "For golfers applying alone!"(https://www.teetimes.tokyo/for-golfers-applying-alone)
