- Video conferencing solutions from NTT Communications offer global, single-vendor support for networks, devices, and services

- Improved stability of the video conferencing system enhanced communications throughout the company- NTT Communications video conferencing solution is introduced to meet system requirements of each location

Chori Co., Ltd. has a 150-year history in the textile business with diversification into chemicals and

machinery operations. The company has facilities worldwide, with a focus on markets in China.

As a global company, effective business communication is vital, and Chori was an early adopter of

video conferencing technology. However, their multi-vendor system was plagued by instability.

Troubleshooting video conferencing problems with multiple vendors was difficult and restoring

system processes after a failure was time-consuming.

“Our president at that time placed an emphasis on the importance of communications in our

business. He was determined to introduce new reliable video conferencing despite the substantial

costs.” said Satoko Nakayama, Executive Officer, System Department at Chori. In addition to cost,

Chori faced management challenges operating video conferencing in a variety of countries and

regions with different telecommunications environments.

- System instability and difficulty isolating problems across multiple vendors were affecting business communications globally

Chori turned to their ICT partner, NTT Communications, for a video

conferencing solution. NTT Communications offers a variety of video

conferencing services, including Arcstar TV Conferencing, for video

conferencing over dedicated networks, and Arcstar Video Conferencing, for

cloud-based video conferencing over the internet.

The solution NTT Communications provided for Chori included three

services:

• Arcstar Universal One VPN connecting Chori offices in China.

• Cloud-based Arcstar Video Conferencing for cost-effective, multi-device

video conferencing over the internet, for Chori overseas locations.

• In Japan, Arcstar TV conferencing for video conferencing between

branches, using gateway servers.

“Devices and networks need to be managed together to ensure video

quality,” said Katsuhito Aoki, Department Manager, System Department at

Chori. “We also need coverage for locations worldwide. NTT

Communications offers a complete solution including networks, devices,

installation, and maintenance, with support for our offices around the

globe.” Ms. Nakayama added, “Post-installation service is also important.

NTT Communications offered a very professional follow-up service that

alleviated the burden of follow-up for our overseas offices.”

Usability has been a key factor in the enthusiastic adoption of NTT

Communications solutions at Chori. The video conferencing applications

start quickly after installation and offer easy to understand documentation,

popular screen layouts, and small details, like remote control button

positions, that have helped improve employee satisfaction.

“I appreciate the effort to which NTT Communications has gone to verify

each one of our requests during the implementation process,” said Mr.

Aoki. “Arcstar Video Conferencing works with a wide variety of

internet-connected devices. This makes it a cost-effective solution at many

of our locations. Some small offices overseas are strategically important

and we rely on video conferencing to communicate with our staff.“

The new video conferencing solution was rapidly adopted throughout

the Chori global offices, with many employees making full use of the

system within months of the launch.

“The NTT Communications video conferencing solution appeals to all

users and has proven itself useful in our everyday business,” said Ms.

Nakayama. “With this solution, we hold the start-of-the-year meeting

and half-yearly kick-off meeting, connecting Japanese sites and

overseas sites, such as Shanghai and Dalian. We share our president’s

message, management policy, and award ceremony for

high-performers. These real-time interactions give us a feeling of

unity.”

“Frequent business travelers in our sales division asked if they could

connect to business partners using video conferencing,” added Mr.

Aoki. “NTT Communications helped coordinate the project and Chori

now enjoys active communications with our partners. This has

increased business efficiency and reduced travel costs.”

Video conferencing has also enabled staff at Chori overseas offices to

receive training and participate in interviews without the need to

return to Japan. This and other benefits have contributed to

working-style changes that are increasing productivity. Future plans

for video conferencing include interconnection with Microsoft Skype

for Business as well as expansion on dedicated overseas networks to

further collaboration.

“Communication tools are an important element of our business

infrastructure and we depend on fast support for troubleshooting, ”

noted Ms. Nakayama. “We chose NTT Communications for its proven

expertise and reliability. I look forward to having them continue to

meet our expectations.”
