Three TX towers at Chikura; one RX tower at Gotenyama. Each transmitter has its own overseas destination: Johor Bahru, London or Chicago. NLN supplies actual receive-site locations in its ITU filings, so all three links can be followed to a physical facility at the far end.

Three towers together on the ridge, each carrying a thirteen-element log-periodic. The Johor-facing lattice tower is the oldest; the London and Chicago arrays occupy the two newer monopoles.

The fourth HF tower is the separate receive site, about 13 km north of Chikura. It carries one thirteen-element log-periodic.
Gotenyama also carries microwave links to Chikura, Maruyama CLS and Tsumoriyama. Through Tsumoriyama it reaches Toyosu CC1, putting the receiver on the same Tokyo access network as the transmitters.

Chikura had grown from one tower to three. The Johor-facing lattice tower is the one visible in the older satellite image; the London- and Chicago-facing monopoles are the additions. Ryota does not date that older image. The 2023 licence comparison lists Johor alone; his 2024 comparison adds London and Chicago.
Sawajiri gained north- and south-facing microwave dishes on the Ajigaura–Kitaura path. Ryota’s Street View comparison brackets their addition. Elsewhere on the northern routes, Omitama’s dishes are already visible in March 2026 imagery and Kitaura’s in April.
The HF sites share NLN’s microwave network with Maruyama CLS and Toyosu CC1. There are two approaches to Toyosu: through Gotenyama and Tsumoriyama, or from Maruyama along the coastal chain through Mihara, Kamogawa-no-Inu and Mother Farm North.
Arteria fibre feeds NLN’s tower just outside the Ajigaura CLS compound. Two microwave paths run from there to SCSK SI1 in Inzai, one via Ushiku and one via Nagara.
Nagara’s third dish pair connects through SoftBank Kamogawa to Maruyama CLS, joining the northern cable landing and Inzai routes to the network serving the HF sites. Ryota’s August 16 overview names and photographs the Kamogawa station, completing this section of the route.
Nagara and the new Kamogawa station have licences dated 9 June 2026 and complementary 6585/6745 and 6645/6805 MHz channels. Kamogawa’s 7640 MHz channel pairs with a 7480 MHz channel at Maruyama, both at 126.2 mW. The Maruyama record retains the older 6615/6585 MHz combination identified in Ryota’s station table.
