As of 2026, Ikuta Erina is no longer part of Up Front and has transferred agencies to Yoshimoto Kogyo.
Since rules and ways of working might differ from Up Front, here below will follow an overview with general information about the agency.
Fanmail
Both letters and presents are accepted by the agency. Depending on the event, you will be able to hand these over at the entrance to staff. This will usually be announced beforehand on the information section on Ikuta Erina's fan club site.
Letters and gifts can also be sent to the artist through mail. There are two addresses that can be used to send fanmail to:
Yoshimoto Kogyo Holdings Co., LTD.
Tokyo Headquarters
TO: Ikuta Erina
160-0022
5-18-21 Shinjuku, Shinjuku-ku, Tokyo
JAPAN
Yoshimoto Kogyo Holdings Co., LTD.
Osaka Head Office
TO: Ikuta Erina
542-0075
11-6 Namba Sennichimae, Chuo-ku, Osaka City
JAPAN
Either address should be fine, but as an international fan (and knowing Eripon's location) Tokyo might be the easiest choice.
When writing down the address, make sure to include Eripon's name as written above. Otherwise the staff might not be able to tell who it is addressed to. Note staff will check the contents before giving the mail to the artist. Here below follows a list with prohibited gifts:
- Food and beverages with an expiration date less than 2 weeks away
- Opened, used or handmade items (likely not applying to handmade letters but rather gifts)
- Items requiring refrigeration or freezing
- Animals (pets, insects) and plants (fresh flowers however are accepted)
- Cash/vouchers (gift cards, coupons etc.) / Transportation tickets such as airline/shinkansen / Any other type of ticket
