The name Welcome in Chinese / Japanese...

いらっしゃいませ is the Japanese greeting that you'll hear just about every time you enter a sushi bar, restaurant, or shop in Japan.

This calligraphy would be appropriate to hang by the entry door of your business or shop.

Note: Because this title is entirely Japanese Hiragana, it should be written by a Japanese calligrapher.

道場へようこそ or “Dōjō e yōkoso” means “Welcome to the dojo” or “welcome to [our] dojo” in Japanese.

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

歡迎光臨 would be the ultimate Chinese “welcome mat.” Except it will be on your wall, and people will not step on it.

In a somewhat literal translation, you could say it means “I feel happy as I welcome you, as you have brought a shining light to this place with your arrival,” or more simply, “I am happy you've come as your presents brightens up the place.”

It has become common for this greeting to be announced by the staff upon the arrival of any customer into a fancy store in China. You will also see these characters on the “welcome mats” in front of 4 and 5-star hotels in China.

Having this on a wall scroll is an extra nice touch. I have seen a few horizontal scrolls with this phrase on the wall behind the reception desk of better hotels or near the front door of fine shops. At the fanciest department stores and restaurants in China, several greeters (almost always young women) will stand by the front door, all wearing sashes with this phrase embroidered. As you walk in, they will bow and say “huan ying guang lin” to welcome you to the establishment.

Note: The first two and last two characters do make words in Korean Hanja but are seldom used as a sentence like this in Korean.

お帰りなさい is a common Japanese way to say, “welcome home.”

This is said by a person greeting another as they return home. It's a typical phrase that is almost said by reflex as part of Japanese courtesy or etiquette.

Sometimes written as 御帰りなさい (just the first character is Kanji instead of Hiragana).

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

This is the Japanese surname Settai.

This also is a word that means to receive (a visitor), to admit (allow somebody to enter), reception, welcome, to receive and treat, to entertain, or wait upon.

This Chinese phrase suggests that a good host will make guests feel like they are returning home or are as comfortable as they would be at their own homes.

賓至如歸 is also the Chinese equivalent of “a home away from home,” and is used by Chinese hotels, guest houses, and inns to suggest the level of their hospitality that will make you feel at home during your stay.
