As NTKJ enters its 40th year of business, we would like to thank our clients for their continued patronage.
RHK Japan has served as the sole international agent for NTKJ for more than 30 years, during which time Mr. Okuda has greatly contributed to success in international sales.
In correspondence with Mr. Okuda’s retirement at the end of this year, it has been decided to merge RHK Japan and NTKJ. NTKJ hopes to continue the strong precedent of success that Mr. Okuda has achieved.
Beginning in October 2018, duties that have previously been performed by RHK Japan will gradually be assumed by NTKJ as follows.
・Custom product orders (creating new molds)
Until October 31st, 2018, RHK will continue to be responsible for custom product orders that require new molds (including accepting purchase orders and generating invoices).
From November 1st, 2018,> NTKJ will be responsible for all custom product orders that require new molds (including accepting purchase orders and generating invoices).
・Custom product orders (using pre-existing molds) and off-the-shelf product orders
Until December 31st, 2018, RHK will continue to be responsible for custom product orders that use pre-existing molds (including accepting purchase orders and generating invoices).
From January 1st, 2019, NTKJ will be responsible for all custom product orders that use pre-existing molds (including accepting purchase orders and generating invoices).
