The Japantoday definition “Omotenashi” involves the subjugation of self in service to a guest, without being “servile”. Anticipating needs is at the heart of the concept." https://www.youtube.com/watch?v=5xlf-gQZa3Y
Whilst this may seem like a Gee-Whiz-Wow! statement to the world; its point of origin is ancient Sanskrit "atiti-devo-bhavah" - your guest is no less than divine so must be treated with respect.
Modern Japanese standards of service are unbeatable and the world has much to learn from Japan.
