Received job offer from Japanese company – They want to present it in a meeting. Need advice!

Hey everyone,

I'm a European IT professional and I just completed a recruitment process with a Japanese company. They've informed me they want to make me an offer (yay!) but instead of sending a written offer first, they're asking to schedule a meeting to present it.

Few questions since I'm not familiar with Japanese work culture:

1. Is this common practice in Japan? In Europe, we usually receive written offers first to have time to review them properly.
2. What should I expect during this "offer presentation" meeting?
3. Could I ask to receive the offer prior to the meeting?
4. About negotiations – while it's very common to negotiate offers in Europe/US if they don't meet our expectations, I'm wondering if this is culturally acceptable in Japan?

Additional context: The company will be sponsoring my work visa as I'm not a Japanese resident. This is for an IT position.

For those with experience:

• Are there specific aspects of Japanese job offers I should pay special attention to?
• Are some elements typically more negotiable than others?
• Any specific considerations regarding visa sponsorship that I should keep in mind?

Would really appreciate insights from people who went through similar situations. Thanks!
