FAQ

Can I visit without a reservation?
Do not assume walk-in access. Confirm the date, group size and purpose directly with the operator.
Can visitors see patented technology?
Not necessarily. A visible process is not proof of a patent; specific rights require a separate public-record check.
Is English-language support available?
Permanent English support could not be confirmed. Contact the venue early and arrange interpretation if needed.
